It’s an international standard for data interchange, so why would it say anything about localized strings? CLDR records such information.

Also, nobody writes or says “the apples cost dollar 2” in English, although “… $2” is common.

Great – how do I add the week of the year, though?

Americans write $ before the price and say “dollar(s)” after it …

In Japan, the year is based on an era count that changes with each new tenno – certainly not optional. In several languages, it is normal to say the minutes first in something like “20 past 3” or “10 to 5”. Your general argument is right regardless.

Many Americans speak dates more like MMMM D., ’YY. I’ve never heard a numerical/ordinal month being spoken in English, but frequently in other languages.

On the other hand, it’s somehow considered normal to write $ on the left side of a price, but say “dollar” after it.

ISO 8601 standardizes how to count weeks. That’s a very good convention to have. It also specifies notations for repeated time spans and other useful stuff.

Only people who just need an unambiguous way to represent a single date or time are better served by the quasi subset RFC 3339.

That’s basically the Blanxart Calendar.

Leap weeks are usually more convenient than days outside the week cycle. Alternatively, a single holiday after every other month has its appeal.
Blanxart Calendar
The Blanxart Calendar was a proposal from 1986 by Albert Blanxart Pàmies for implementing a world-wide 6-day week starting in the year 2000. The calendar design eliminates Mondays, keeping the other d...

You’d need an extra 6-day week in almost seven out of eight years, though.
(m × 366 + n × 360) / (m + n) matches the Gregorian mean leap year of 365.2425 days for m = 699 and n = 101.

With 5-day weeks, it’s about 1 leap in 20 years: (m × 365 + n × 370) / (m + n) = 365.2425 for m = 1903, n = 97.

According to ISO 8601, a bare two-digit number (string) should be parsed as a century CC. If this was to be interpreted as a full date, it world probably point to the beginning of that century.

In einem älteren Artikel wird richtig ausgeführt, dass momentan alles an der russisch-orthodoxen Kirche scheitern wird – außer natürlich die einseitige Rückkehr der Westkirchen zum prä-gregorianischen Computus paschalis, was Franziskus ernsthaft erwogen haben soll, aber im ÖRK keine Mehrheit hätte.

> Leo XIV. sagte, es seien schon "mehrere konkrete Lösungen" vorgeschlagen worden, die es unter Wahrung des Prinzips von Nizäa ermöglichen würden, das höchste Fest der Christen gemeinsam zu feiern. Welchen er sich konkret vorstellt, sagte er nicht.

Das klingt richtig konstruktiv und zielführend. 🙄

Ich bin ein Special-Interest-Account mit einer entsprechenden Schlagwortsuche 🤷

Wochen sind viel praktischer für die Organisation des Alltags, aber 52–53 sind tatsächlich zu viele, um die aktuelle in Kopf zu haben.

Wenn jeder Monat immer genau vier oder fünf Wochen hätte, würde niemand mehr die Wochennummer des Jahres verwenden und wahrscheinlich auch nicht mehr den Tag des Monats, sondern sowas wie „vierte Woche des Monats“ bzw. „vierter Freitag des Monats“.

Das kann Outlook schon sehr lange, muss nur so konfiguriert werden.
Das Datum in der Windows-Taskbar kann man hingegen nicht einfach entsprechend anpassen.

Das Problem sind nicht Kalenderwochen, sondern die völlig unsystematischen Längen der Monate, wodurch die in keiner einfachen Beziehung stehen.

Außerdem, wer weiß schon sicher, welcher Tag des Monats gerade ist?
Monat ja, Wochentag ja (manchmal plus/minus eins), Tag des Monats plus/minus drei.

In the non-Catholic world, not much really. It took Britain roughly another 170 years to switch, and Orthodoxy double that (if at all).

It’s funny, though, to see it with week numbers.

No. The comma is correct as is the arbitrary number of digits following it, but your time zone is completely ill-formatted.
May 19, 2025 at 6:27 AM
ISO requires the ‘T’ between date and time parts, though.

You can shave off a couple of bytes if you don’t use extended format with separators or use UTC either explicitly (‘Z’) or implicitly.

12345678T012345+7890

1234-67-90T23:56:89+12:45

time_t is just 4–8 bytes, of course.

11:00 or rather the 60 minutes from 11:59 through 11:00 counting backwards, whereas 1 PM was the 60 minutes 12:00 through 12:59 counting forwards, excluding 13:00!
It’s really strange to combine that with cardinal minutes and seconds, if you think about it; “half”/“quarter” “past”/“to” works though.
April 26, 2025 at 6:49 PM
A similar thing happens in clock times. 1 AM is ordinal: the first hour completed after midnight passed; but 01:00 is cardinal, so 00:00 educated, but 0 PM and 0 AM don’t.
The difference to eras is that AM and PM designate fixed-length periods and both count from the start, otherwise 1 AM would be …

because they are steps of repeating cycles.

By the way, “2025 AD” would be expanded to something like “(in) the 2025th year of the Lord” in English.
