What two months rhyme?

Answer 1

Thirty days hath September is a traditional English mnemonic rhyme, of which many variants are commonly used in English-speaking countries to remember the lengths of the months in the Julian and Gregorian calendars.

Here is one version of the rhyme attributed to Mother Goose:

Thirty days hath September,

April, June, and November

All the rest have 31,

Except for February.

Another version that rhymes perfectly is from an unknown source and date:

Thirty days hath September,

April, June, and November;

Thirty-one the others date,

Except in February, twenty-eight;

But in leap year we assign

February, twenty-nine.

Answer 2

November, December

Answer 3

June and moon rhyme.
