“30 days hath September…” (January and February joke)

An old calendar rhyme is:
 
“Thirty days hath September,
April, June, and November;
All the rest have thirty-one,
Excepting February alone,
And that has twenty-eight days clear
And twenty-nine in each leap year.”
 
However, January and February are cold months that seem even longer. “Thirty days have September, April, June and November. All the rest have 31 except January and February which drag out forever” was printed in the Indianapolis (IN) News on January 23, 1979. “Love Mack McGinnis’ update: ‘Thirty days has September, April, June and November. All the rest have 31 except January and February which have 80’” was printed in the Detroit (MI) Free Press on February 22, 1982. “Thirty days hath September, April, June and November. All the rest have 31 except January and February which have 80. — William C. Hopkins” was printed in The Reader’s Digest in 1988.
 
The saying has been popular on Twitter, where January is often given an especially long number of days.
 
     
Wikipedia: Thirty Days Hath September
“Thirty Days Hath September…”, or “Thirty Days Has September…”, is a traditional verse mnemonic used to remember the number of days in the months of the Julian and Gregorian calendars. It arose as an oral tradition and exists in many variants. It is currently earliest attested in English, but was and remains common throughout Europe as well.

Handy phrase I use when trying to remember how many days are in each month: 30 days have September, April, June and November. All the rest have 31, except for January which feels like it has 47. And February obviously.
