Memorization Tip:
A common way to remember the months with 31 days is through a traditional rhyme:
“Thirty days hath September,
April, June, and November.
All the rest have thirty-one,
Except February alone,
Which has twenty-eight, rain or shine,
And on leap years, twenty-nine.”
This rhyme helps to quickly identify which months have 30 days and, by exclusion, which have 31 days.
