Lot of talk of numerics only. The problem there is knowing what format the information is in since clearly there are 3 possibilities. Without context and during certain parts of the month you're hosed. Best to remove ambiguity and go with the alpha numeric format.

DD MMM YY (or alternatively YYYY)

11 Aug 2023

Ambiguity gone.

This is me but without the dashes. Haha I know l, what’s wrong with me..

But I’ve also started using 10/Aug in emails to make things crystal clear.

Anyway.

No love for DD-YYYY-MM?

filename.`date +%s`

This is big pp idea and I like it.

Everyone talks big game about the file names but forget how important standardizing on log time stamps is too. When I’m able to pipe a bunch of logs into sort, I get so happy.

join south africa and (sorta) japan, use YYYY-MM-DD as a default - sorts well, zero ambiguity.. at least until some joker starts popularising YYYY-DD-MM, anyway

I’ve always used it for everything

Facts. The sorting system for files inevitably makes YYYY-MM-DD more optimal. I tried to resist but it doesn't work.

For speaking or writing it out going month then day feels natural, although I know it’s a regional thing. If you’re going number format, it should always go smallest to largest (DD-MM-YYYY) or largest to smallest (YYYY-MM-DD). For file names, definitely the latter so you can sort by alphabetical and everything is in order.
