Do you know how many minutes there are in February?
Believe or not, the answer is 8!

1) The exclamation mark is actually the mathematical factorial sign, which is ambiguous at the end of a sentence.

2) wolframalpha.com/input?i=8%21+

3) The answer is about 75% correct. 97/400 years¹ have an intercalary day of February 29 under the modern Gregorian calendar. This Feb (2023) does not.

4) Every 21 months or so, modern time standards see fit to add an extra second to the day. But in practice these happen in June or December, So 28! is 75.75% correct.²

¹ Years divisible by 400 or divisible by 4 but not 100 are leap years. Thus (100−3)/400 = 97/400 as from en.wikipedia.org/wiki/Gregoria
² This corrects an earlier version which was based on an incorrect ratio of 99/400. Also, my instance character limit changed.

Point 3) would've been my nitpick.

Thanks for point 4), didn't consider leap seconds.

@niplav @Arpie4Math I do like the nitpicks, but consider leap years and leap seconds to be... A nitpick.

@dneary @niplav I like the joke answer to the question: Which month has 28 days? All of them.
