“How many months have 28 days?” (riddle)

There is a popular riddle about the days in the month:

Q: Some months have 31 days, some months have 30 days. How many months have 28 days?
A. All twelve of them.


February, of course, is the only month that has 28 days and no more, but all the months have at least 28 days. The joke has been cited in print since at least 1896.

The teacher asking questions—teachers are quite apt to ask questions, and they sometimes receive curious answers. The question was as follows: “Now, pupils, how many months have 28 days?” “All of them, teacher,” replied the boy on the front seat.—Utica Observer.
