How about March Fourteenth as "American PI-Day" and 22.07. as "international, sensible and widely understood PI-Day", each according to the used date format?

[-] fossilesque@mander.xyz 19 points 1 month ago

A third excuse for pi, you say? I think it suits it.

[-] Hawk@lemmy.dbzer0.com 8 points 1 month ago

22/07 is already known as "Pi Approximation Day"

Fun fact: 355/113 = 3.14159...
Close enough to pi so that using it for calculating the earth's circumference from its diameter is accurate to within 3 meters.

[-] ohwhatfollyisman@lemmy.world 64 points 1 month ago

... or to within π meters?

[-] bluewing@lemm.ee 3 points 1 month ago

The engineer in me wants to tell you round it up to 3.5 just to be safe. Maybe even 4 might be better...........

Why have one pi day when you could have 2?

[-] fossilesque@mander.xyz 15 points 1 month ago

One for sweet pies, one for savoury.

[-] TexasDrunk@lemmy.world 14 points 1 month ago

You're forgetting tau day, June 28th. That's 2*pi. Then we get 3 holidays.

[-] GlennMagusHarvey@mander.xyz 4 points 1 month ago

looks at today's date

...darn, I did forget Tau Day. :(

for the greater good

[-] niktemadur@lemmy.world 4 points 1 month ago

2*pi already sounds like two holidays rolled into one!

[-] AChiTenshi@sh.itjust.works 3 points 1 month ago

3 is even better!

[-] fogstormberry 2 points 1 month ago

and four pies

[-] powerofm@lemmy.ca 13 points 1 month ago

We should have approximately 3 pi days

[-] coffee_whatever@lemmy.world 2 points 1 month ago

I propose that during a 113 day period we have exactly 355 pi days. That would be an avrage of 3,14159 pi days per year

FUCK DD/MM FORMAT YYYY-MM-DD IS SUPERIOR

--ISO-8601 GANG

[-] humbletightband@lemmy.dbzer0.com 12 points 1 month ago

MM-DD-YY will make you cry

[-] Michal@programming.dev 26 points 1 month ago

That's nice and helps remember it's 22/7. Americans can have their 14th of March, and let 22/7 be the international pi day.

Some very confused Americans trying to remember the names of the 13th - 22nd months.

Speaking as someone from a blue country on that map. Most of the world is wrong though. The ISO standard is designed that way for a reason. Not putting the largest unit first is just silly.

Also https://m.xkcd.com/1179/

[-] FiskFisk33@startrek.website 8 points 1 month ago

Personally I can get behind YMD and DMY (while sticking to ISO would be preferrable for obvious reasons), but what on earth possessed people to come up with MDY?

[-] Zink@programming.dev 3 points 1 month ago

I have no idea why it started that way, but in everyday speech we say dates with the month first. So that makes MDY just the thing everybody is used to.

Fortunately the ISO format YYYY-MM-DD still has the month before the day, so I don’t have to worry about my fellow Americans getting it confused.

[-] AceCephalon@pawb.social 3 points 1 month ago* (last edited 1 month ago)

You know, I thought about it after reading the comments here, and I've thought of one possible explanation for MM-DD-YYYY, that being the order you effectively get the useful information from a date.

Going by DD-MM-YYYY, you read the first part, and that tells you the day in a month, but not which month, just skimming that first section gives you no actually useful information about how near or far it is without reading the second.

Doing MM-DD-YYYY on the other hand, you first read the month, which immediately tells you what part of a year it is, and if it's relatively sooner or later, and then reading the second part of the date just gives more precision, rather than the whole useful answer.

So basically, it makes it easier to skim dates within a year with more useful information listed first, whereas putting the year first would just delay or offset that same skimming method.

Day first gives a range of error between 0 and roughly 330 days without reading further, whereas Month first gives a range of error of only up to 28 to 30 days depending on the month.

Shame there isn't a 31st of April then, could make it extra wrong.

Pretty sure that iso standard of yours specifies using what you call military time, or 24 hour time system, which USA doesn't use widely, so even they don't use this standard

[-] dch82@lemmy.zip 7 points 1 month ago

What are you even talking about?

Most countries use a 24hr clock

Many countries that use a 24hr clock don’t even use ISO8601 officially.

The only countries I know officially use ISO8601 are certain East Asian countries.

I don’t think they even use ISO8601 in the US Military.

[-] xx3rawr@sh.itjust.works 18 points 1 month ago

But Pi Day doesn't end with the day. There can be Pi Hour, Pi Minute, Pi Second, Pi Milisec...

Is this some worldly date format that I'm too American to understand?

[-] dQw4w9WgXcQ@lemm.ee 7 points 1 month ago

A man with an assault rifle at an island killing 77 people, many bellow 18, kinda ruined pi-approximation day in Norway.

But then we'd have to deal with the savage barbarism of writing it with the day before the month.

[-] GlennMagusHarvey@mander.xyz 11 points 1 month ago

then write the year before the month before the day 😈

[-] Dasus@lemmy.world 4 points 1 month ago

Going by the numbers, using DD/MM is the civilised way and MM/DD the archaic one.

[-] Mubelotix@jlai.lu 6 points 1 month ago

What's the 14th month?

[-] Toes@ani.social 5 points 1 month ago* (last edited 1 month ago)

Where's the love for tau day

[-] lennivelkant@discuss.tchncs.de 3 points 1 month ago

I was looking for you. Or someone like you. Or someone other than you.

I need a Tau advocate and you got the job.

[-] bluewing@lemm.ee 5 points 1 month ago

I have a Daughter who was born on Pi day. When she was little. she would tell you it's the second most important day, right after Christmas. Pi Day actually became a school wide fun day because of her, (small rural schools can be fun that way). We would bring a couple of pies for her math class to celebrate. Oddly, she much prefers a strawberry cheese cake for her birthday over pies.

I suspect she will NOT allow the change...........

It's close, but the math checks out.

[-] JokeDeity@lemm.ee 3 points 1 month ago

Jokes on you, I'm too dumb to get it!

[-] joyjoy@lemm.ee 2 points 1 month ago

You'd confuse the Americans.
