Thirty days hath October,
April, May, and February;
January, July, and September
have twenty-eight,
all the rest have twenty-nine.
Excepting last year, that’s the time
when June’s days were thirty-nine,
December’s, thirty-one and August’s, thirty-five.

If you doubt the reason
behind my rhyme, then
make your own calendar
to mark your own time.
