... except in 100, when it doesn't, except again in 400, then it does.
As someone who's dyslexic and nearly 40 I will never remember this for as long as I live no matter how many times I've heard it.
There's a much easier way to remember. Ball your two hands into fists in front of you and put them together so that you have your knuckles on top, sans thumbs. Start counting from left, knuckles are hills, the gap between them are valleys. Months falling on valleys are shorter. Months falling on hills are always 31 days.
- January is on a hill.
- February falls on a valley.
- March is hill.
- April is in a valley.
- May is on hill.
- June is valley.
- July is on a hill.
- August is on a hill too!
- September is in a valley.
- October is hill.
- November, valley.
- December ends on a hill.
You have a valley and a knuckle left.
It’s the first time I’ve ever seen it written, though I wrote it myself. I’ve only ever known it verbally because it rhymes!
I just do the knuckles method (you have to remember February, but other than that it’s perfect).
Knuckle bros!
at some point in life I just precomputed the list of length 12 (except the leap year consideration) and memorized it
If the year is divisible by 100 but not by 400 then February has 28 days despite the fact that the year will also be divisible by 4.
Oh yeah. Thanks, Pope Gregory!
It's weird that April didn't know how many days April has.
I see you're trying to be clever but April never mentioned how many days she thinks April has.
She specifically got 'April' wrong in the '30 days has September, April, June and November' mnemonic, saying '30 days has September, March, June and November'
It like the next line in the show.
And he didn't even do all of them, like any good public servant.
Best meeting ever
Ewww a shorts link...
Life is unfair.
Wrong show, that is Malcolm in the Middle.
There are two kinds of people.
One kind can draw an inference.
The other isn't artistically inclined
