It also say YYYY-mm-dd should be date and HH:MM:SS should be time and YYYY-mm-ddTHH:MM:SS should be datetime. But it also allow extremely cursed datetime, many prefer rfc3339
The standard specify a ton features and formats. Thing like day if week so 2015-W4-1 would be the first day of the fourth week of 2015.
But the you have can have periods like “P1Y2M10DT2H30M”, and you can specify start and end dates. So if you want to start an event that runs for 3 months, 20 days, and some time you could write it as “20220212T1133/P3M20DT7H15M”.
And then there’s more like giving the year as an exponent, so 2015 can be written as Y-2.015E3S4.
I always knew starting the week on Sunday was messed up. Thankfully there’s an ISO to back me up
