That's easy to memorize (for the current century) using the following verse:

53 weeks hath 2004,
and 2009,
and 2015, 2020, 2026, 2032, 2037 and 2043,
and 2048 and 2054,
and 2060, 2065, 2071, 2076, 2082, 2088 and 2093,
and 2099.

Please note the beautiful rhyme scheme, ABC ACB.

### Re: 1595: "30 Days Hath September"

A few years ago I got fed up with that rhyme ("30 days hath September")
for exactly the reason described by the comic,
so I tried to think of an easier way to remember which months have how many days.

Here's my month-days rhyme: "Seven has long odds, but eight is even longer."

Up through July, the odd numbered months have 31 days.
So 1, 3, 5, and 7 have 31 days.

From August (8) on, the even numbered months have 31 days.
So 8, 10, and 12 have 31 days.

All the rest have 30, except February, which has 28, or 29 on a leap year.

The leap years are every 4th year (0, 4, 8, 16, 20, 24..) except the 100's which are not divisible by 400. (So 2000 was, but 2100 won't be.)

Even and Odd 'till August.

The even/odd number of every month is 30,28/31 days, then it's not from August on.

Thank you for sharing.

It's the key after E, obviously.

i dont get it... whyyyy do we keep this shitty Gregorian calendar ?
You mean, change the months which are roughly based on the cycle of the moon, to align them to weeks which are based on.........nothing???

"Roughly" is the word, though. On average, the Gregorian months are about a day longer than synodic months, whereas 28-day months would be about 1.5 days shorter, so there's not a huge amount in it. And although weeks as such are not based on any astronomical phenomenon, they are very much a real thing in the human world in which we live, and they're simply related to days, which are astronomical. They're certainly more important than the phases of the moon, which are almost irrelevant to living in the modern world.

F is the note after E, but the key of F is the key after C (or I guess after Bb if you're going the other direction).

(Yes, I know this is unhelpful and irrelevant, because the mnemonic is chromatic anyway, so major and minor keys bear no relation to any of it.)
Unless stated otherwise, I do not care whether a statement, by itself, constitutes a persuasive political argument. I care whether it's true.

That's a good example of the strange prevalence of homonyms within a given field that I was going on about here. You have key, the physical lever on a piano keyboard, and key, the scale or set of notes in which a piece of music is based. And that's not all: there's clef, which is the symbol indicating which notes are represented by the lines of a musical stave; and in Cuban and other related music you have the clave, which is both a rhythm in its own right and a kind of rhythmic "map" of the two-bar repeating unit (in a sense that I never fully grokked); there's also claves, a percussion instrument often used to play the clave rhythm. It's only because English used a mixture of borrowing of cognates from different languages and translation (calquing?) that these words are not all identical.

You may want to work on this, speak it out rhythmically and to a nice piano tune and have a 2nd carreer as a musician.

Oh, & HP fans don't have any problem with the number of days in June, either

Reading this bit of the forums is certainly quite interesting, under the current conditions of Intervener's Insanity. Especially with the word that which was originally actually the word that is less absolute than 'must', caught up in it...

(Oh look, and now the quoted months have naturally cycled once more... so loop back January <- October <- July <- June <- May <- March <- September <- April <- February <- December <- August <- November <-, by the number of steps necessary, if there's confusion, and they haven't changed it all again... )
