No only 1 month has 28 days because your asking how many months have 28 days not how many months have 28 days at least it’s a riddle

Dan says

Makayla – I have an event that lasts 28 days and needs to begin and end in a single month. How many months have 28 days for my event?

This riddle is dumb. I have three cats. But according to this riddle’s logic, I could walk up to someone and say I have two cats. Or I have one cat.

This answer is clearly wrong.

The overwhelming majority of native English speakers would take the question “how many months have 28 days?” to mean “how many months have a total of 28 days?” not “how many months have at least 28 days?” or “how many months have a 28th day?”

Someone is trying to be clever by asking this question. They failed miserably.

sinar some of YOU thinking the riddle IS dumb as, just think of peaceful things and GET OVER IT!!!!!

All 12 months have 28 days

Brad says
March 18, 2015 @ 01:29

DUMB, DUMB. How many day does April have??? This answer is 30…
How many days does December have? – 31. It’s not 28.
But If the riddle ask ” how many months have a 28th day? Than it would be all of them.

Brad says
March 18, 2015 @ 01:35

Even thier answer is worded differently to the question. I can write stupid riddle too.
How many hours in a day?
Answer There is a 2 hours in every day for African pigs to eat the flies from red gummy sharks.

Dan says
March 18, 2015 @ 15:22

@Brandon If I needed two cats for a magic trick, and I asked if you had two cats, would you say no?

@B1gears If the riddle asked how many months had a total of 28 days, sure. But it didn’t.

@Hermione I concur :)

@Cayla Correct!

@Brad So December doesn’t have 28 days? If a task takes exactly 28 days, could you do it all in the month of December? If a forest has 1,000 trees and you need to cut down 15 trees for a Christmas tree farm, does the forest have 15 trees for you to cut down?

I get that you were tricked and now you’re angry at the devious riddle and resorting to calling it names, but that’s kind of the point of a riddle. You do realize riddles and brain teasers are tricky, right? How many months have a 28th day isn’t a riddle, it’s a boring question.

ugh. it’s not that hard a concept. (scroll to end for simple answer/reasoning)- it’s a riddle, thus meant to mislead, thus why it is called a riddle. but it is also a clever riddle. all months have 28 days. to those whining, ‘no some have 30 etc’ yeah, which means they have 28 + 2 months. if you have 20$, and are asked if you have 8$, yo don’t not have 8$, because you weren’t asked if you have 8$, or exactly 8$. if you have 20$, you have 4$ 17$ 6.66$ 3.141594$. you don’t have 21$ or 0$ however. riddle is clever, one of the many reasons is it says this without saying this, put ppl are willing to say february before the question is finished.

to ‘all english people would take it,’ wow, i’d like to meet you, some kinda diety that knows how every creature thinks/infers, filtered of course, somehow, by those who speak english. oh the enlightenment!! -but yes, the ‘way people would take it ‘commonly but certainly not absolute, is exactly, WHY it’s a riddle. an effective one.

but regardless, if you were chinese, the ‘misleading’ language is why it called a a”riddle”. if it was, ‘which months have 28 days, but not more or less than 28 days, ‘ that wouldn’t be a riddle, it would be a really really really stupid question. but if it makes you happy, subtract the fun, common sense; “february every 4 years,”. there shouldn’t be that much debate there either.

it’s like a magic trick. this misled here is february, it puts that in your head, to distract you from thinking, ‘or looking’ at the ‘exact’ language, which asks simply, how many months have 28 days. “at least” isn’t necessary. If you have 10$, and are asked if you have 7$, yes, you do. you don’t not have 7$ because you have a 10$ bill. the question was not, “do you have exactly 7$?”, such inferences are incorrect.

(conclusion, put)
Simply, it’s a riddle, any answer that is not, “all of them” is wrong. additional inferences are the intended mislead, if you consider them, congrats! you just proved the riddle a good one.

this is probably from the free internet “IQ test” from Mensa. It’s pure bull because if you don’t expect it to be a riddle, it doesn’t matter how “smart” you are. Because of how the language works (not only English) it is expected that when you phrase the question like that, that it’s about the total amount of days. It works in a way that even if you don’t say the word “total” you still mean that while you have to say the word “at least” if you don’t mean the total. It’s not really a clever riddle if you ask me, because it only works if the person doesn’t know it’s a riddle. Any sane person would probably be right otherwise. A good riddle is one that isn’t close to obvious even if you know it’s a riddle

Katie says
October 18, 2015 @ 08:26

It’s All 12 months that’s have 28th days! It’s a tricky & awesome riddle! If it had word differently then the answer would have be 11 months!

I do not even understand what these guys are saying alreaady the calender has its standared readings and you can not change that. that is 30 days has sept,april,june and Nov they rest has 31 days except Feb with 28 days and not if they how many months has 2days u will say 12 ?huh madness its should be howmany months has the 2nd day bc ech month begins from 1st 2nd and so on.some pple are talking about having a feast for 28days in december thats very stupid bc the calender does not know your feast its has standard readings that can never be alter by your stupid feast for 28 days

Actually they need to specify on the Julian or Gregorian calendar. The Mayans had a month that was only 5 days long so all of them is not a correct answer.

Really? Over one silly question?
What’s worse? all the comments being posted as if the question is such a complicated mathematical problem, or the people that are saying it’s a dumb question. Its a riddle PEOPLE!…

Okay so here’s what you’re saying:

Question: How many animals have two letters in its name?
Average answer: One. Ox.
Real answer: They all have two letters in their name.

Seriously? If I said “dog” and “cat” have two letters in their name I would technically be correct?

Luthan says

The riddle plays on the distinction between “semantics” and “pragmatics”, where semantics is concerned only with what sentences explicitly say, while pragmatics concerns itself with what we imply with our sentences. The question above (how many months have 28 days?) does not explicitly say that it’s looking for months with *only* or *exactly* 28 days, so semantically speaking the correct answer should include any month that has *at least* 28 days (all of them). However, pragmatically we assume that the questioner has a certain amount of knowledge: they know that some months have 30 days, and others have 31, and we might also assume they probably know that no months have any fewer than 28 days. If we assume the questioner knows all this, then we will infer that they already know the answer to the question as it was explicitly asked. It’s a pragmatic norm that we don’t ask questions we already know the answer to, and so we infer that the questioner must be asking some other question. The candidate question that makes the most sense in this context is “how many months have *only* 28 days?”.

So when the answer turns out to be “all of them”, this is only because the questioner is breaking pragmatic norms.

Alternatively, we sometimes ask questions we know the answer to when we are *quizzing* others. But there are assumptions we make when being quizzed too. We assume that the quizzer has assumed some of *our* knowledge – in this context, our knowledge that no months have fewer than 28 days – and so they wouldn’t ask a question with an answer that would be so easy for us. Instead they ask the question which is (arguably) a bit less common knowledge: “how many months have only 28 days?”

And so when the answer turns out to be “all of them”, this is only because the quizzer is breaking pragmatic norms.

So nobody’s really “wrong”, it’s just that the “right answer” is different depending on whether we’re concerned with pragmatics or just semantics.

That’s my take anyway.

The only reasonable person here says
March 14, 2018 @ 13:08

People be like: All 12 months have 28 days, it’s just that the ones that aren’t February have 2 or 3 days after as well

Yeah and I’m right when I say one month has 28 days, doesn’t matter if there’s another 11 months that have 28 days too! Wait, that’s not how it works, the question is stating a specific amount, not a minimum.

And it’s funny how people are comparing months to objects. If someone asks me if I have 8 dollars and I have 20, I will say I have 8 dollars because I can take the 8 out of the 20 (and thus I actually have an 8 within that 20). I cannot take 28 days out of a month of 30 or 31 because months aren’t physical containers. Heck, in the example I gave I’d say “no but I have 10 if you have change” if I had two ten dollar notes.

Caster says
November 14, 2018 @ 11:37

Check it out. Not all months have 28 days in them. If you wanted to be correct in saying that you’d have to relay it as such “all months have at least 28 days in them” or “all months are 28 days or more”

I don’t get it, say it again? Because I watched azzyland (the easiest game) and the question was How many months have 28 days and she didn’t know so she lost the game.

Response to Luthan says
May 3, 2019 @ 20:56


Your assessment of the semantics of the question is inconsistent. You say that the question does not explicitly ask for ‘exactly’ 28 days and therefore we should include all months with at least 28 days. But the question does not ask for months with ‘at least’ 28 days either. You are inferring this and you’re essentially saying that we cannot assume A, but we should assume B. This decision is completely arbitrary under the consideration of semantics alone.

Because the question contains some level of ambiguity, an assumption must be made when answering it (unless you ask the questioner for clarification), and if that assumption is not arbitrary, then we are now dealing with pragmatics, about which I pretty much agree with what you’ve said.

February has 28 days, but all the months have 28 in them.

Claudia says
May 27, 2019 @ 03:28

I get it.. Hahhaha.. February is the 2nd months and it only has 28 days.. So 28 devide by 2 equal to 12

Claudia says
May 27, 2019 @ 03:30

Sorry.. I’m wrong?? 28 – is because after 4 years it will change.. So. The answer is 24..24 devide by 2 because February is the 2nd months.. The answer is 12

Markeon says
May 28, 2019 @ 11:29

Al have 28 days

Nick says
July 29, 2019 @ 16:22

I would disagree with this. I believe the answer is 1 (except every 4 years) when it is zero. If they asked how many months have at least 28 days, then it is 12. Let me as you this.

How many wins do the Yankees have. Today’s answer is 67. You wouldn’t say :60 because at one point there was a 60th win would you?

Those who answered 12 months probably answers the following question true.
A human hand has three fingers. true or false?
three fingers exists out of five so it’s probably true. even though it’s false.
A human hand has three fingers = A human hand has (a total of) three fingers = FASE
How many months have 28 days = How many months have (a total of) 28 days? = 1

Well the question was ”how many months have 28 days” well the answer is 1 month Because Feburay has 28 days but sometimes it is a leap year because every four-years it is a leap year!

How many minutes does an hour have? Can ylu answer 15? 35? 3.54? No, its 60.

mason says
January 24, 2023 @ 01:45

Guys the answer is this its asking how many as in the total amount since every single day has more that 28 days its asking how many see the word many that means the total amount of days have 28 and since all the months except february have more than 28 days that means like january july august they all have like 30 or 31 and that is more than 28 days so it technically has 28 days because 28 + 3 is 31 28 makes 31 and it is not asking for how many months have exactly 28 days its tricking you and saying how many months have 28 days or simplified how many months have over 28 days.

Gilbert says
January 25, 2023 @ 16:56

this really brain teaser I don’t understand and how that works who is the first person to count days and months again it doesn’t work with Time time is different from months In my suggestion we need to count everything and restart of months

Sam says

All of the 12 months
