-Slightly less trivial live hack is that if you want to know how many work days a month has, check dates 29, 30 and 31 for work days and add 20. For example, at the time of writing, in April 2026, days 29.4. and 30.4. are both work days, so April has 2 + 20 = 22 work days. (You have to subtract work holidays, i.e. Christmas, manually.)

 In Spain both rhyme and knuckle are well-known, and usually taught to children (the rhyme suitably [https://es.wikipedia.org/wiki/Calendario_gregoriano#Duraci.C3.B3n_del_a.C3.B1o_gregoriano translated], of course). For some reason, I've always found it easier to just remember the number of days by memory than resorting to any mnemonic trick.  I tend to use the known numbers to check if I remember the mnemonic correctly, and not vice versa. Also, it's usual to see people wondering which number corresponds to which month (e.g. October is month 10), which I also remember no problem since I have memory.

 How do people remember it if it doesn't rhyme?- madness! {{unsigned ip|162.158.38.218}}
 :Personally I could swear I heard "except for February which has none" as a child, and recall thinking as a child that made no sense. However, literally none of the other variants work- "alone" doesn't rhyme with "one" (...even though they should; are there any accents that pronounce those the same?), and it also doesn't scan; this comic actually sent me to Wikipedia to look; turns out they have a massive list of variants but the lack of rhyming there is painful. The only ones that work are those that give up on describing February (ex. "Except for February—and that's no fun!"). I strongly suspect based on the lack of rhyming that the rhyme originated with something like "which has none" and was modified to make sense at the expense of rhyming. --[[Special:Contributions/173.245.54.34|173.245.54.34]] 05:28, 28 October 2015 (UTC)
+::While, in my normal inflection of speech, "wonn" certainly doesn't rhyme with "al-own", I find it quite easy to go for a nearly-but-not-quite rhyme by extnding the first and shortening the second.  There's worse 'rhymes' out there.  Traditional local accents also vary a lot in my area, between towns a few mere miles apart (e.g. "book" => "buk" or "bewk") and I'm sure I could find some old person who still spoke a pure enough form of their own local dialect to effortlessly pull this trick off, without even trying, even if it doesn't match in the modern 'smeared-English'.
