#3Also in case you did not know, the leap year is not on even hundreds of years, i.e. 1900 was not a leap year, and neither will 2100 be under the current calendar.
The exception is every four hundred years, which means 2000 was a leap year, as would 1600 have been, and 2400 will be.
This means the year is on average 365.2425 days long[1] -- a constant that I've found surprisingly useful to memorise.
[1]: Because 365 + 1/4 - 1/100 + 1/400.

#4In Portugal (idk about other countries) we use something like:
- Use knuckles and spaces between them
- Start with left-most pinky knuckle (in
- Count across hand: knuckle (31), space (30), knuckle (31), etc.
- Jump to right hand's index finger knuckle after left index (so it's two times knuckle, when passing from left to right hand (for July and August) and continue.
February is special: 28 or 29 days

#5I was taught as a kid to use the knucke mnemonic [0]. Easy to use, and doesn't take much thought outside of counting the months

How is this different from the knuckle mnemonic mentioned as the first thing in TFA?

#8My wife makes a fist and counts her knuckles and divots on her left hand:
pinky Jan 31
divot Feb (28/29)
ring March 31
divot April 30
middle May 31
divot June 30
pointer July 31
(now head back the other way)
pointer August 31
divot September 30
middle October 31
divot November 30
ring December 31
I don't know where she learned it, but it's genius.

Yeah, this is what I do. Or used to do. I followed an interesting progression with it -- at some point, I stopped having to actually look at or touch my knuckles to do it, then after a number of years, I found that I (mostly) just have the months lengths memorized.

#10> In numeric format, these months correspond to 4 6 9/11.
Easy to remember for Romans: IV VI IX XI (”if you write the month number with two letters that aren’t identical”). I think that worked under the Julian calendar (https://en.wikipedia.org/wiki/Julian_calendar#Table_of_month...)
