Days of the Week in Portuguese

You are standing at a bus stop in Lisbon, phone in hand, trying to figure out when the number 28 tram actually runs. The little printed schedule taped to the pole says "seg. a sex." on one line and "sáb., dom. e feriados" on the other, and for a second your brain just stalls. You know your Portuguese numbers. You know your colors. But "seg." and "sáb." might as well be hieroglyphics. Then a woman waiting next to you says something to her friend about "a reunião é na segunda-feira," and you catch the word "segunda" and think: wait, isn't that the number two? Why is a day of the week also a number?

You are not imagining things, and you are not alone. Portuguese really does name most of its weekdays with numbers instead of names, and once you see the pattern, you cannot unsee it. Here is the full list so you are not left guessing at bus stops:

That is the quick answer. But there is a much better story underneath it, one involving a 6th century bishop, a Church calendar reform, and a word that used to mean "holy day" and now means "flea market." Stick around, because once you know why Portuguese counts its days instead of naming them, you will never forget the list again.

The Full List, With Pronunciation and Literal Meaning

Before anything else, let's slow down and look at all seven days properly, side by side with what they literally mean and how to say them out loud. This is the table worth bookmarking.

Notice something right away: five of these seven words share a piece, "-feira," and the other two, sábado and domingo, stand completely apart. That is not random. It is the fingerprint of a very old decision, and we are about to dig into it. According to Practice Portuguese, this is also the moment to note something English speakers trip over constantly: Portuguese never capitalizes the days of the week in the middle of a sentence. You write "eu trabalho na segunda-feira," not "eu trabalho na Segunda-feira." Your instinct from English will fight you on this for weeks. Let it lose.

Now, if you actually want to be able to say these seven words out loud in a real sentence, not just read them off a table like this one, that is a different skill than recognizing them on a page. Comigo is built around exactly that gap: you get a short spoken quiz that checks how you actually sound, not just whether you can tap the right multiple choice box.

Why Portuguese Counts Its Days Instead of Naming Them

Here is the single most interesting fact in this entire post, so let's give it room to breathe.

In most European languages, the days of the week are named after gods and planets. English kept a Germanic version of this system: Monday is moon day, Saturday is Saturn's day. Spanish, French, and Italian kept a Latin version almost intact: lunes, lundi, and lunedì all mean "moon day" too, and martes, mardi, and martedì all point back to Mars. Portuguese used to follow the exact same Roman calendar as its neighbors. Somewhere along the way, it stopped. Why?

The answer has a name attached to it: Martinho de Braga, also known as São Martinho de Dume, a bishop working in the northwest of what is now Portugal in the 6th century AD. Martinho was on a mission to stamp out lingering pagan practices among the recently Christianized population of the region, and one of the things he objected to was the fact that ordinary people were still naming their days after Roman gods, moon and sun, Mars, Mercury, Jupiter, and Venus, every single week, without thinking twice about it. To a bishop trying to build a Christian identity from the ground up, that was a problem worth solving.

So Martinho borrowed a numbering system the Church already used internally for its liturgical calendar, the days of Holy Week. In that system, days were not named for gods, they were counted, using the Latin word "feria," which meant a holy day or a day set aside from ordinary work. Sunday, the day of the Resurrection, was "feria prima" or simply "Dominica," the Lord's Day. Monday became "feria secunda," the second day. Tuesday became "feria tertia," the third. This pattern continued straight through to Friday, "feria sexta," the sixth day. According to a detailed history from Tomorrow Algarve, Martinho pushed this numbering out from the liturgical calendar into everyday civil speech across the region that would eventually become Portugal, and it stuck in a way it never quite did anywhere else in the Latin-speaking world.

Over the centuries, "feria" softened into "feira" as the Portuguese language evolved away from Latin, and "feria secunda" became "segunda-feira." The same happened right down the line: "feria tertia" to "terça-feira," "feria quarta" to "quarta-feira," "feria quinta" to "quinta-feira," "feria sexta" to "sexta-feira." A related, more technical breakdown of this exact shift can be found at iLanguages, which lays out how the Latin ordinal numbers, secunda, tertia, quarta, quinta, sexta, survived almost unchanged inside these compound words for well over a thousand years.

Here is the detail that makes people grin every time they hear it: that same word, "feira," the one that used to mean a holy day set apart from work, is the everyday Portuguese word for an open-air market today. Walk through Lisbon or Porto on a weekend and you might stumble into a "feira da ladra," a flea market, or a farmers' market advertised as a "feira." The word took a long, strange road from "sacred day of rest" to "stalls selling vegetables and secondhand furniture," and both meanings sit peacefully in the language at once, as noted in that same Tomorrow Algarve piece. A similar retelling of Martinho's calendar reform, with more on how it interacted with the wider Iberian Church, appears at Kylian's blog on the history of Portuguese weekdays.

It is worth sitting with how unusual this actually is. Spanish, spoken right next door, went through the same Christianization process and kept martes, miércoles, jueves, and viernes anyway, all named for Roman gods. French did the same. Italian did the same. Only Portuguese, shaped by one bishop's calendar reform in one corner of the Iberian Peninsula, ended up with a fully numbered week. If you have ever wondered whether Portuguese is hard to learn compared to Spanish, this is a case where it is actually easier once you understand the logic, because a numbered system is more predictable than a list of seven unrelated names.

Why Saturday and Sunday Refused to Fall in Line

If Portuguese numbered every day starting from Sunday, you would expect Saturday to be "feira sétima," the seventh day. It is not. It is sábado. And Sunday, which you might expect to be "feria prima," the first day, is domingo instead. Why did these two hold out?

Because the Church never renamed them in the first place. Saturday, sábado, comes directly from the Hebrew word "Shabbat," the day of rest commanded in Jewish law, filtered through Latin as "sabbatum," a root you can trace in Etymonline's entry on the word "Sabbath", long before Martinho de Braga ever touched the calendar. It was already a religiously loaded word, the day of rest itself, and there was no need to replace it with a number, since the whole point of the numbering system was to get rid of pagan names, not sacred ones. Sunday, domingo, comes from "Dominica," meaning "the Lord's day" in Latin, referring to the day of Christ's resurrection, the most important day on the entire Christian calendar. Renaming that to a number would have defeated the purpose of the reform. You do not demote the Lord's Day to "day one" when the whole reform exists to honor the Church's calendar in the first place.

So the numbering system only ever applied to the five ordinary working days sandwiched in between two days that already had names too sacred to touch. That is also, quietly, the answer to a question a lot of learners ask: why isn't Saturday "sábado-feira"? Because sábado was never part of the feira system to begin with. It kept its own name the entire time, the same way domingo did.

Learning to Say Them Out Loud

Reading "segunda-feira" and saying it with confidence are two very different skills, and this is where a lot of learners quietly get stuck. Let's break the pronunciation down piece by piece.

The suffix "-eira" appears in all five feira days, and it has a fairly consistent sound: something close to "FAY-rah" in English approximation, with the stress landing hard on that first syllable, FAY. The "ei" in Portuguese behaves like the vowel sound in the English word "day," and the final "a" is soft, almost swallowed, especially in fast Brazilian speech. Lingopie's pronunciation guide breaks this same pattern down syllable by syllable if you want to hear more examples of "ei" behaving this way elsewhere in the language.

Here is the stress pattern for each day, laid out so you can practice them one at a time.

If you would rather see the whole list laid out fresh with a slightly different set of example sentences, Berlitz's guide to the days of the week in Portuguese and Semantica Portuguese's vocabulary page both cover the same seven words with their own audio and practice exercises, which is a handy second angle once this list has had a chance to sink in.

A note on that "s" sound in terça, quinta, and sexta: in Brazilian Portuguese it often softens toward a "sh" sound before certain consonants, so "sexta" can come out closer to "SEHSH-tah" depending on the speaker's region. FluentU's guide to the days of the week has audio examples that make this regional variation easier to hear than any written description can manage. If you have already worked through greetings like how to say good morning in Portuguese, you have probably noticed this same soft "s" creeping into "bom dia" in casual speech. It is the same sound family showing up again here.

One more small thing: the "u" in "segunda" and "quinta" tends to get compressed in fast speech, so native speakers often glide right past it. Do not worry about nailing every vowel with textbook precision on day one. Getting the stress in the right place matters far more for being understood than perfecting every vowel sound.

The Grammar: Gender, and How to Say "On Monday"

Here is a fact that trips up almost every English speaker at some point: the five feira days are grammatically feminine, while sábado and domingo are masculine. This matters because it changes which articles and adjectives you pair with each word.

Segunda-feira, terça-feira, quarta-feira, quinta-feira, and sexta-feira all take feminine articles: "a segunda-feira," "essa terça-feira," "toda quarta-feira." Sábado and domingo take masculine ones: "o sábado," "esse domingo," "todo sábado." If you learned that all days of the week are simply "the days" and never thought about gender, this is the moment to start paying attention, because getting it wrong will not stop someone from understanding you, but it will mark you instantly as a learner.

Now for the part that actually matters most for everyday conversation: how do you say "on Monday"? In English you just say "on," full stop, for every day. Portuguese uses the preposition "em," which contracts with the article that follows it. Since segunda-feira is feminine and takes the article "a," "em" plus "a" becomes "na." So "on Monday" is "na segunda-feira," and "on Wednesday" is "na quarta-feira." Since sábado and domingo are masculine and take the article "o," "em" plus "o" becomes "no." So "on Saturday" is "no sábado," and "on Sunday" is "no domingo." Both The Portuguese Guide and a detailed breakdown at Portuguese Learn walk through this exact contraction rule with more example sentences if you want extra reps.

Here is a table that covers the most common time expressions you will actually need, from "on Monday" all the way to "next Monday."

A quick clarification on the plural forms: "às segundas-feiras" and "aos sábados" describe something that happens on that day as a general habit, closer to "on Mondays" in the English sense of "every Monday, as a rule," rather than one specific Monday. "Você trabalha aos sábados?" means "Do you work on Saturdays?" as a general pattern of your life, not just this particular Saturday. A grammar-focused rundown at Kylian's guide to Portuguese weekdays covers this same singular-versus-plural habit distinction with a few extra example sentences if the concept still feels slippery.

It is worth pausing on why the gender split matters beyond just sounding polished. Portuguese adjectives and articles have to agree with the noun they modify, so if you describe "a próxima segunda-feira" as feminine correctly but then, out of habit, call "o próximo sábado" feminine too, saying "a próxima sábado," a native listener notices instantly, the same way an English speaker notices "an banana" instead of "a banana." It is a small rule, but it is exactly the kind of small rule that separates someone reading Portuguese from someone speaking it correctly without stopping to think.

If you have already read about how to talk about dates and years in Portuguese, you will recognize this contraction pattern, since "em" contracts with articles the same way whether you are talking about a day, a month, or a year. The logic is consistent across the whole calendar vocabulary, which makes it worth learning properly once rather than memorizing each case separately.

Reading a grammar table is one thing. Actually producing "na segunda-feira" correctly at conversational speed, without stopping to think about which contraction to use, is a completely different challenge, and it only gets solved by saying it out loud, over and over, until it stops feeling like math. That is the exact kind of practice Comigo's spoken quiz is built around: you say the sentence, and you get told immediately whether it landed right, word by word, instead of just picking an answer from a list and moving on.

How People Actually Talk: Dropping the "-Feira"

Textbooks will have you saying "segunda-feira" every single time, and that is correct, and it is also not quite how Brazilians talk to each other on an ordinary Tuesday. In casual, spoken Brazilian Portuguese, the "-feira" ending gets dropped constantly. "Vou te ver na segunda" ("I'll see you on Monday") is far more natural in everyday speech than the full "vou te ver na segunda-feira," which can sound a little stiff, almost like you are reading off an official notice. Preply's guide to the days of the week confirms this pattern and notes that the shortened forms dominate spoken Brazilian Portuguese, while the full forms hang on in formal writing, invitations, contracts, and official schedules, where dropping the suffix would look sloppy.

So when do you keep the full form? Written invitations ("A festa será na sexta-feira, dia 12"), official business hours posted in a store window, formal emails scheduling a meeting, and anything printed on a government form. When do you drop it? Texting a friend, chatting at a bar, casual small talk about weekend plans. Sábado and domingo never had a "-feira" to drop in the first place, so they stay the same length in both registers.

You will also run into abbreviated forms constantly once you start looking at Brazilian calendars, printed bus schedules, store hours, or appointment reminder cards. These come in two flavors: a three-letter abbreviation, and a numeric form using the ordinal number plus a small raised "a."

According to Migaku's breakdown of Portuguese days of the week, the "seg., ter., qua., qui., sex." family of abbreviations shows up everywhere from printed pharmacy hours to bus timetables, and the numeric versions like "2ª" and "3ª" are especially common on appointment cards and simplified Brazilian calendars, where space is tight. If you see "2ª a 6ª" printed on a shop door in Brazil, that means "Monday through Friday," using the numeric shorthand for segunda through sexta.

Asking and Answering "What Day Is It?"

The single most useful question in this entire vocabulary set is short: "Que dia é hoje?" It means "What day is today?" and you will use it constantly, whether you are confirming plans, double checking whether the pharmacy is open, or just making conversation while waiting for coffee. According to Practice Portuguese's breakdown of this exact phrase, the answer follows a simple pattern: "Hoje é segunda-feira" in its full form, or the far more common casual version, "Hoje é segunda."

A close variant, "Que dia da semana é hoje?", literally "What day of the week is today?", is used when you want to be extra specific that you are asking about the weekday and not the calendar date. If you actually want the date itself, the number and month, you switch questions entirely and ask "Qual é a data de hoje?", which is a different question with a different kind of answer, something like "Hoje é dia 15 de março." Mixing these two up is an easy trap: asking "que dia é hoje" when you actually want the date will just get you told what weekday it is.

Here is a short natural exchange showing how this plays out in real conversation:

If you can already ask how someone is doing in Portuguese, stringing "que dia é hoje" onto the front of that same small-talk exchange is a natural next step. A full mini conversation might run: you greet someone, ask about their day, confirm the date, and wrap up with a plan for later in the week, something like "Nos vemos na sexta, então! Até lá," see you Friday then, see you later. If you close that kind of exchange the way most Brazilians actually do, casually rather than formally, it is worth knowing how to say goodbye in Portuguese too, since "até lá" and its cousins show up constantly right after you have just pinned down a day to meet.

That same short exchange is also a good excuse to round out the rest of your basic phrasebook. Knowing how to say hello in Portuguese gets you into the conversation, please and thank you carry you through the middle of it, and good afternoon in Portuguese covers you if the chat happens later in the day instead of first thing in the morning. None of these phrases are complicated on their own, but strung together with a day of the week, they turn a flashcard list into something closer to an actual conversation.

Why English, Spanish, French, and Italian All Made a Different Choice

It helps to step back and see Portuguese next to its linguistic cousins, because the contrast is what makes this whole system click.

English kept a mix of Norse and Germanic gods layered onto a Roman planetary framework. Monday is moon day. Tuesday comes from Tiw, a Germanic war god roughly equivalent to Mars, a substitution Etymonline's entry on "Tuesday" traces in detail. Wednesday comes from Woden, or Odin. Thursday comes from Thor, the thunder god. Friday comes from Frigg, Odin's wife. Saturday, oddly, kept its Roman root directly, Saturn's day, without a Germanic substitute, as Etymonline's entry on "Saturday" points out. Sunday is sun day. The English-speaking world just never had a Martinho de Braga figure showing up to scrub the pagan names out of everyday speech, so they survived, more or less intact, straight through to your phone's calendar app today. Wikipedia's overview of day name etymology lays out the full god-by-god correspondence across multiple language families if you want to go deeper.

Spanish, French, and Italian, meanwhile, kept the original Roman version almost word for word. Lunes, lundi, and lunedì all mean moon day. Martes, mardi, and martedì all point to Mars. Miércoles, mercredi, and mercoledì point to Mercury. Jueves, jeudi, and giovedì point to Jupiter. Viernes, vendredi, and venerdì point to Venus. These three languages went through the same broad process of Christianization as Portuguese, under the same Church, and yet none of them adopted a numbered week the way Portuguese did. That detail alone tells you how local and specific Martinho de Braga's influence really was, confined mostly to the region that became Portugal rather than spreading across the wider Latin-speaking Church. iLanguages makes this same side-by-side comparison directly, setting the Portuguese numbered system against its planet-named Romance siblings.

It also helps to remember just how far this particular numbering system travels. Portuguese is spoken by roughly 260 million people across Brazil, Portugal, and several African nations including Angola, Mozambique, and Cape Verde, according to Wikipedia's overview of the language. Every single one of those speakers, from São Paulo to Lisbon to Luanda, uses the same numbered feira system for the working week. A decision made by one bishop in one small region in the 6th century ended up shaping how a quarter of a billion people talk about Tuesday, which is a strange kind of staying power for a calendar reform nobody outside a history class ever hears about.

Put next to all of that, Portuguese suddenly looks less arbitrary and more like the odd one out with the better excuse. English speakers often assume every other language just does things "randomly," but once you know that segunda literally means "second," terça means "third," and so on straight through sexta meaning "sixth," you are not memorizing seven unrelated sounds anymore. You are counting. That is a genuinely easier system to hold in your head than English's grab bag of half-remembered Norse gods, even if it feels backwards on day one.

Putting the Days to Work in Real Sentences

Knowing the words is only half the job. You need to be able to drop them into an actual sentence when someone asks you to grab coffee, confirms a work meeting, or tells you the gym is closed. Here are a dozen sentences you are likely to actually use or hear.

Notice the pattern repeating across almost every one of these: "na" for the feminine feira days, "aos" or "às" for the habitual plural, and the date reference sliding in wherever it is needed, past, present, or future. Once that contraction becomes automatic, sentences like these stop requiring translation in your head, and they just come out.

This is also exactly where a lot of scheduling conversations pair naturally with telling time, since you rarely say just "on Thursday" without also saying "at three o'clock" or "in the morning." If you have not already worked through how to tell time in Portuguese, that pairs directly with everything in this section, since "a reunião é na quinta-feira às três da tarde" is a completely normal, complete sentence you will actually need.

Reading twelve sentences off a table gets you halfway there. The other half is saying them, out loud, at a normal pace, without stalling on the contraction. That gap between recognizing a sentence on a page and producing it under pressure, in a real conversation, with someone waiting on your answer, is where most self-taught learners quietly stall out. Nobody notices the gap until a coworker actually asks "você trabalha aos sábados?" and the answer takes four seconds too long to arrive.

The Rest of the Calendar Vocabulary You Will Need Nearby

Days of the week rarely travel alone. The moment you start scheduling things in Portuguese, a small cluster of related words comes along for the ride, and it is worth picking them up here rather than hunting for them separately later.

"Fim de semana," literally "end of week," is the standard word for weekend across both Portugal and Brazil, and you will hear it constantly in casual plans: "O que você vai fazer no fim de semana?", "What are you doing this weekend?" "Dia útil" is the flip side, a workday or weekday, and it shows up on store signs and shipping estimates: "entrega em três dias úteis," "delivery within three business days." "Feriado" specifically means a public holiday, a day off work for the whole country, and it is a different word entirely from "férias," which means vacation, so do not mix the two up even though they look related on the page. A general dictionary reference like Cambridge's English-Portuguese dictionary is a fast way to double check a word like "feriado" against its exact definition and example sentences if you are ever unsure.

Months and seasons sit just one step further out from this same cluster, and while this post is not the place to go deep on either, a quick bridge is worth having. The months, "janeiro, fevereiro, março, abril, maio, junho, julho, agosto, setembro, outubro, novembro, dezembro," are lowercase in Portuguese exactly like the days are, following the same capitalization rule. The four seasons are "primavera" (spring), "verão" (summer), "outono" (autumn), and "inverno" (winter). Italki's combined guide to days and months covers both sets side by side if you want to move on to full dates next, and pairing that with the year vocabulary you already have gets you most of the way to describing any date on the calendar, month, day, and year, in a single natural sentence.

Both Portugal and Brazil use the exact same day names, month names, and season names, which is a small relief after learning that plenty of other vocabulary genuinely does diverge between the two, as noted in a comparison of regional calendar terms at Lisbon Language Cafe. Two more vocabulary rundowns worth keeping in your back pocket as you build out this cluster are Portuguese Learn's guide to weekday-adjacent phrases and its companion piece on related calendar expressions, both of which collect extra example sentences beyond what fits in one post.

Once you are comfortable naming the day, the natural next step is naming the date that goes with it, "quinta-feira, dia 12 de junho," Thursday, the 12th of June. Rio and Learn's guide to dates in Portuguese picks up exactly where this post leaves off, walking through how day names, numbers, and months combine into a full spoken date.

A Simple Trick for Remembering the Order

If the number connection still feels shaky, here is the mental shortcut that makes it click for most learners within a day or two.

Portuguese counts the week starting from Sunday as day one, even though Sunday itself is not called "day one" out loud. Domingo holds that first spot silently, as the reference point, and then the numbering picks up from Monday onward: segunda is the second day, terça is the third, quarta is the fourth, quinta is the fifth, sexta is the sixth. The trick is this: take the number hiding inside the Portuguese word, and subtract one, and you get how many days you are counting past Sunday to land on that weekday. Segunda, two, minus one, equals one day past Sunday, which is Monday. Terça, three, minus one, equals two days past Sunday, which is Tuesday. Keep going and the whole week falls into place using nothing but subtraction.

An even simpler version some learners use: just remember that the Portuguese number word buried in each day name is always exactly one higher than its normal position if you started counting weekdays from Monday as one. Segunda has "dois" energy but means Monday, so mentally you are always shifting by one. Once you drill this a handful of times, it stops being math and just becomes recognition, the same way you do not consciously calculate that "Thursday" comes after "Wednesday" in English anymore.

Some learners find it easier to just sing through the list rhythmically a few times a day, the same way English speaking kids learn the alphabet, treating "segunda, terça, quarta, quinta, sexta" as a five-beat chant that ends with sábado and domingo tacked on at either side. A numbers refresher, like the breakdown at Rio and Learn's guide to Portuguese numbers, makes the connection even more obvious, since seeing "dois, três, quatro, cinco, seis" laid out next to "segunda, terça, quarta, quinta, sexta" makes the shared root practically jump off the page.

Common Mistakes English Speakers Make

A handful of errors show up over and over again, and knowing them in advance saves you the embarrassment of making them in front of a native speaker.

The first is capitalization. English speakers write "Segunda-feira" out of pure habit, because that is how English treats every day of the week, every time, no exceptions. Portuguese does not do this. Mid-sentence, days stay lowercase: "eu vou lá na terça-feira," never "eu vou lá na Terça-feira." The only time you would ever see a capital letter is if the word happens to start a sentence, and even then it is capitalized for that reason alone, not because it is a day name.

The second is confusing "sexta" with "sexto." Sexta, ending in "a," is the feminine ordinal used in "sexta-feira," Friday. Sexto, ending in "o," is the masculine version of the same ordinal, meaning "sixth" in a completely different context, like "o sexto andar," the sixth floor. They look nearly identical and mean the same underlying number, but swapping them in a sentence about the calendar will sound off to a native ear immediately.

The third is gender agreement across the board, not just with sexta and sexto. Learners get used to feira days being feminine and then accidentally apply feminine articles to sábado and domingo too, saying "a sábado" instead of "o sábado." Since sábado and domingo break the pattern of the other five days entirely, they need to be memorized as their own small exception rather than folded into the general feira rule.

The fourth is a register mismatch in either direction. Some learners cling to the full "-feira" ending in every single sentence, even in casual texting with friends, which reads as stiff and overly formal, almost like a bank notice. Others go the opposite way after learning that Brazilians drop the ending, and start dropping it even in situations that call for the full form, like a wedding invitation or an official work schedule, where the shortened version looks careless. Reading the room, formal writing versus casual chat, is the actual skill here, not picking one form and using it everywhere.

The fifth, smaller but common, is forgetting the contraction entirely and saying something like "em a segunda-feira" instead of "na segunda-feira." The uncontracted form is technically parseable but sounds distinctly non-native, almost robotic, the linguistic equivalent of saying "going to the" without ever blending it into "goin' to the" the way a native English speaker naturally would.

Frequently Asked Questions

Is Sunday the first day of the week in Portuguese? Structurally, yes. The old feria numbering system treated domingo as day one, the reference point the rest of the week counts forward from, even though nobody calls it "primeira-feira" out loud anymore. In practical terms, though, plenty of Portuguese speakers, like plenty of English speakers, mentally treat Monday as the "start" of the working week, since domingo and sábado form the weekend on either side.

Do Portugal and Brazil use the same day names? Yes, and this is one of the rare corners of Portuguese vocabulary where the two countries line up perfectly. Segunda-feira, terça-feira, sábado, domingo, all of it, are identical in Lisbon and in São Paulo. Plenty of other everyday words split between the two countries, but the days of the week are not one of them.

How do you say "weekend" in Portuguese? "Fim de semana," literally "end of week." It is used the same way across both Portugal and Brazil, in phrases like "bom fim de semana," have a good weekend, which you will hear constantly on a Friday afternoon.

How do you abbreviate the days of the week in Portuguese? The standard three-letter abbreviations are dom., seg., ter., qua., qui., sex., and sáb., matching domingo through sábado in order. You will also see numeric shorthand like 2ª for segunda-feira and 6ª for sexta-feira on Brazilian calendars, bus schedules, and appointment cards.

Why isn't Saturday called "sábado-feira"? Because sábado was never folded into Martinho de Braga's numbering reform in the first place. It kept its own name, borrowed from the Hebrew "Shabbat" through Latin "sabbatum," long before that reform happened, the same way domingo kept "Dominica," the Lord's Day. Both were already sacred names, so there was nothing for the Church to replace.

Why do Brazilians sometimes just say "segunda" instead of "segunda-feira"? Casual spoken Portuguese trims the "-feira" ending constantly, the same instinct that makes English speakers say "gonna" instead of "going to." The full form survives in writing, invitations, and formal schedules, where dropping it would look sloppy, but in everyday conversation, the short form is what you will hear far more often.

Where That Leaves You

You started this at a bus stop, confused by "seg." and "sáb." printed on a schedule. You now know that those seven words, five of them numbers wearing a disguise and two of them ancient religious names that refused to budge, carry an entire chapter of Church history inside them. A 6th century bishop in northern Portugal decided pagan planet names had no business surviving in a Christian calendar, so he counted instead, and that decision echoes every single time a Brazilian or a Portuguese speaker mentions what day it is, more than fourteen hundred years later.

The list itself is short enough to memorize in an afternoon. Saying it naturally, dropping the "-feira" at the right moments, contracting "em" into "na" without thinking, landing the stress on "FAY-rah" instead of flattening it, that takes actual spoken practice, the kind that a page of text alone cannot give you. If you want to build that muscle with real feedback instead of guessing whether you sound right, Comigo's quiz is a quick way to find out where you actually stand, one spoken sentence at a time.
