My 1969 calendar works in 2025
Discussion
And it comes with some nice Yellow Submarine art.
I stinkin love this calendar. It belonged to Mom, and I found it and hung it on my wall when I was in 6th grade (back in 1990 or so).
I left it behind when I went away to college in 1995, but I'm cleaning out my parents house and brought it home and hung it on the wall, only to realize that this is its year (a one out of seven chance, doc!). Anyway, I still freaking love the artwork
You never know when an old calendar might come in handy! Sure, it's not 1985 right now, but who knows what tomorrow will bring?

It was the summer of '69

It's 1969. we all live in a Yellow Submarine
Edited to fix link. Hopefully.
That is not a Blue Meanie, that's Jeremy Hillary Boob, PhD. He's a real Nowhere Man.
It will be valid again in 2031, 2042, 2053, and 2059.
any calendar 28 years away from any year will be correct - 1969 is 56 years before 2025 which is twice 28 ----- its actually more often just 7 years apart as long as neither year has a leap day
Until you worry about the gregorian calendar. The year 2100 won't be a leap year, so this trick won't work.
It works for 1969-2025 because 2000 was a year where we skipped skipping the leap year.
1600 was a leap year, 1700 wasn't, 1800 wasn't, 1900 wasn't, 2000 was, 2100 won't be, etc
i appreciate that in 2000 we skipped skipping the day that we usually skip 75% of all other years XD ----- anyway, i vote that we completely re-write the calendar to reflect the moon. like it was originally meant to be. 13 months baby
Lunar calendars do exist, and they are objectively worse.
I say we do 13 months if 28 days each, and then we leave one day at the end of the year not a part of any month or week and we just party.
Two of those days on leap years.
It still won't line up with the lunar cycle of 29.5 days
this works for me. or better yet, we figure out a way to slow down the rotation of earth so that there are only 100 days per solar orbit and then we can have fully metric calendars and clocks
I'd rather slow it down just a hair and we can go with 360. We fuck up Egyptian mythology, but we get nice divisibility with a base 60 system.
That's only about 21 minutes
i like it. then we also divide each day into 360 degrees where each degree is 4 minutes. i want all clocks to be literal progress bars, or radial bars, counting from 0 to 359 each day.
With 7 years apart there will be a leap year somewhere in between. So you actually can reuse a calendar after 5 or 6 years, depending on how the leap years line up. Sometimes the one you want gets skipped over and it takes 11 years instead.
true! my bad on the latter portion of the comment. so it stands at 28 years being the minimal guaranteed match
Except at the end of a century when a leap year gets skipped in 1700, 1800, 1900, 2100… - not sure how it works out then.
So clearly Seymour Chwast it's insane
Nice
Jeremy!!! 🤩🥰
Hilary!!
It was bound to happen
Peter Maxx would be pleased.
Hey John. Blue meanies 'av been sighted in the vicinity of the theatre. What are we going to do?
Newer and bluer meanies!
Peace and love, peace and love
Nice.
The yellow submarine art is creepy. Still can’t watch that movie
Fun fact for the frugal: there are only 14 different calendars.
...until you start caring about Easter.
(It's nice that the calendar has Ringo's birthday. Happy birthday, Ringo!)
I impressed my co-worker* the other morning by mentioning it was Ringo's birthday after he rescued a beetle.
* he was not all that impressed. But mildly!
Or the Moon in general. Jewish and Islamic holidays follow a lunar ar calendar. Christianity is on a luna-solar calendar. Easter falls on the first Sunday after the first full moon (lunar) after the spring equinox (solar)
There are also 14 possible lunar calendars, since you need a leap month about every 19 years. Since they aren't synced to the solar calendar, that means there are 196 luna-solar calendars (14×14)
Personally, I think we should switch to a 28 day, 13 month calendar with 1 day not a part of any week or month at the end of the year (two on leap years) so all the months are nice and even and it leaves us with only two possible calendars. Then if you need a lunar calendar, there are still 15 of those but now there's only 28 luna-solar calendars
Holidays aren't universal, so I'm gonna stop you before you start caring. Also, if we did start caring, then a 1969 calendar would not work in 2025.
Sorry, I already care. Now what?
...but that is a sacrifice I am willing to make. It means we shall have more calendars, isn't that great?
If you just asked me off the cuff, I almost certainly would have guessed higher, but I suppose it makes sense when you consider January 1st (or any particular day) has to start on one of the seven days... and then those seven times 2 (for with and without leap year).
