Sorry to make you memorize this random string of digits. If it helps, it can also double as a mnemonic for remembering your young relatives' birthdays, if they happened to have been born on February 5th, 2018.

ISO 8601 contains way too many obscure formats. RFC 3339 is pretty much a subset and defines only sensible ones. It also allows
2018-02-05 08:02:43-00:00(no T and explicitly specifying no timezone)When you plan your work on weekly sprints, week numbers become second nature.
Yeah but that defeats the purpose of an universal format.
