Amazon is running a Prime Day sale on July 16 and 17. Setting aside the fact that this is two separate days, neither 716 nor 717 are prime numbers. They should've done 7/19 instead.

I maintain that dd/mm/yyyy and mm/dd/yyyy are stupid.

Big -> small is how we read numbers:

yyyy/mm/dd

[-] Old_Jimmy_Twodicks@sh.itjust.works 48 points 3 months ago

I prefer the simple dy/my/dy/my format (with the year reversed for added ease of use). For example, today would be 14/02/70/72.

NIST and ISO have stopped responding to my emails, but I'm optimistic that the Türk Standardları Enstitüsü will eventually adopt it as their preferred standard.

I prefer the MYOWN-16080 standard of yy/dm/md/y/y. Also the year units are randomly swapped for encryption

[-] hddsx@lemmy.ca 6 points 3 months ago

What a shitty standard. Where are the check bits? Are you using PGP?

[-] BackOnMyBS@lemmy.autism.place 3 points 3 months ago

lmaoooo and the fucking year digits are backwards 🤣🤣🤣 i knew the date and it still took me a while to figure it out

Julian date club 24199

[-] Nurse_Robot@lemmy.world 14 points 3 months ago

Yeah, but you have to admit mm/dd/yyyy is way more stupid. Small -> big makes more sense than middle -> small -> big

[-] hddsx@lemmy.ca 6 points 3 months ago

For every day purposes, absolutely. For programming? Nope, the only right answer is big->small.

Honestly, the alternative to every day use is to stop using numbers for the month

[-] odium@programming.dev 5 points 3 months ago

The problem with three letter month codes is language to language difference. Numbers are more universal.

12 is smaller than 31 is smaller than ∞, though.

Really, we can all come up with vastly reasonable reasons the date system we prefer makes the most sense... but in reality it's all very subjective. Not only will different methods be appropriate for different situations... but some people just prefer their own way.

It's all really moot, though. We should have been using stardates for the last 55 years anyways.

Actually, I disagree that DD/MM/YYYY even qualifies as being small to big.

If you actually treat it as a counter from 01/01/2024 onward, note that the first digit that moves is actually the second digit in the 8-digit representation. In terms of significance, the most significant digit is the 5th one in the string, then counting down the significance it's 6th, then 7th, then 8th, then jumps back to the 3rd, then the 4th, then the 1st, then the 2nd.

[-] Nurse_Robot@lemmy.world 2 points 3 months ago

A day is less than a month, is less than a year

[-] booly@sh.itjust.works 4 points 3 months ago

Yes, and recurring dates naturally drop the year, so MM/DD better fits that general rule.

[-] esc27@lemmy.world 3 points 3 months ago* (last edited 3 months ago)

What if we just count all the nanoseconds since 1601 and divide by 100.

I still don't get that timestamp approach. Especially after learning how unix/linux handle it...

At least modern AD tools can automatically do the date conversions now.

[-] hddsx@lemmy.ca 1 points 3 months ago

Because it’s a basic data structure that holds time, instead of multiple interrelated ints…. And it’s easy to do math on.

[-] some_guy@lemmy.sdf.org 1 points 3 months ago

^^ This is the only acceptable way to write out the date numerically. I'll die on this hill.

[-] fubbernuckin@lemmy.world 1 points 3 months ago

Yes but small is more relevant since you're more likely to know the big. therefore i propose we put minutes ahead of hours.

[-] hddsx@lemmy.ca 1 points 3 months ago

Big is more important than small. If your use case has the big stuff in context, drop the big.

[-] Artyom@lemm.ee 11 points 3 months ago

You mean YYYY-MM-DD right? Right?!?

[-] odium@programming.dev 2 points 3 months ago

That would not give a prime number
