I always say that the children only need to learn the first part of the rhyme as they already know some have 30, some have 31 and February has 28 or 29.

So they learn:

**Quote:**

30 days hath September, April, June and November...

They then know that all the rest have 31 except that "Pesky February" which messes it up.

With regard to leap years tell the children as long as the last two digits of the year divide by 4 - it's a leap year.

Except the 'century' years; the first two of digits also have to be divisible by 4. Or, more accurately, not only divisible by 100, but also by 400 - so 2000 was, but 1700, 1800 and 1900 weren't. Although tbf, it would be a very mean 11+ maths question that included February to March 1900 in its span
