#ISO8601

2026-02-07

Kennards Hire you are out of your fucking minds.

d MMM YYYY format on the booking form.

YYYY-DD-MM format on the confirmation email.

I got the confirmation email and logged back in to fix the hire booking, since I assumed I'd somehow accidentally booked it for August.

Also their booking form doesn't support Firefox. Hopeless.

@joho

Is it true that only #Sweden and #China use #ISO8601? I forget where I heard that.

I spent a couple of years developing the #DatePicker in #JavaFX, fighting with the datetime library to parse and print dates in as many languages as possible. That was a major learning experience.

ANSI X3.30-1971 (YYYYMMDD) was indeed ratified during the administration of that well-known Commie radical, #RichardNixon.

@njsg

The fun part of that is that a necessary pre-cursor would be going back to get ISO 8601:1988 ratified almost a decade earlier than it was in our universe.

The sad part is that, conversely, in our universe ANSI X3.30-1971 and FIPS PUB 4 had standardized YYYYMMDD years before the IBM PC was invented.

@tykling but #ISO8601 has so many nice things that aren't in #RFC3339 /o\

TIL about date -I which gives you ISO8601 dates without faffing around with the percent sign formatting.

Plus it has a “precision” modifier which can give you the rest: date -Iseconds → 2025-12-29T10:18:20+00:00; date -Ihours → 2025-12-29T10+00:00; etc. (You can truncate the hours to h and it still works.)

Time to update about a million of my shell scripts!

@RichiH OMG, the #ISO8601 Ultras! Didn't know that I NEED those! 😍
Too bad I'm 1500km further south.

My Actual #smallweb kitten experience.
screwlisp.small-web.org/kitten

What I discovered is that #webdev -ing an article "properly" which is to say using all the features your framework provides (i.e. kitten.small-web.org/ ) absorbs an absolute ton of extra work. Comparable to being formal in mathematics. I am interested in how that extra work exposes my own articles to me better later.

I also propose FIPA SL's extension to #ISO8601 as a general time format in #commonLisp . cc @aral

I use the ISO week-date calendar for my personal journal and notes. Today begins the last week of 2025 under that system. It's a good opportunity to reflect on what has happened these 52 weeks and what I want my life to look like going forward. #ISO8601 #2025 #personalThoughts

Screenshot of a calendar displayed on the terminal. The month of December 2025 is shown with the weeks labeled. Week 52 is the 22nd through the 28th. The 29th is the start of 2026-W01.

@FlohEinstein speaking of which...

I've got 50 of those so I won't distribute them too widely, but anyone who finds me can have some

@dgar

I tried to be there and fully aware, on the 12th.

Sadly, I could not figure out, for the life of mine, what the name of the 31st month was, and so the date just passed, without me noticing anything in peculiar.

@cstross Reminds me of the hoops I have to jump through to get #iso8601 dates in my #Debian apps via the `LC_TIME` environment variable and a bespoke `en_SE` “English - Sweden” custom locale. blog.carsoncheng.ca/2021/03/us . This was the “easiest” solution I found in 2022 after exploring options to get #Firefox, #Thunderbird, and other apps to display YYYY-mm-dd HH:MM:SS style time stamps.

In #macOS, I think you just modify `System Preferences > Language & Region > Advanced > Dates`.

@FlohEinstein Nice, but nowadays it should be RFC 9557!

datatracker.ietf.org/doc/html/

Plain RFC 3339 / ISO 8601 is lossy and thus insufficient.
