What China (and Japan) uses is YYYY年MM月DD日, which IMO is the superior date format since it's self-explanatory - the sections are spelled out right there!
Jumbling together year, month and day and having to separate them by counting digits is not an improvement for human readability. (And you have the year wrong.) Any of “27 July 2026”, “July 27, 2026” or “2026-07-27” would be superior.
It's good because it's an actual standard instead of 7/27 which is backwards for half the world. Besides, I'm actually from the future and they delayed the model a year, learning from Anthropic that good models are actually about to bring the end of society.
Don't even have to go that far, outside of white-collar jobs and some groups weirdly obsessed with scheduling, most people don't use calendars at all, but their manager/boss/significant-other does that for them :)
Not really. Spain's traditional format is dd/mm/yyyy with slashes. This applies for a good chunk of Europe. Germany/Austria uses dot, I think nordic countries embraced the dash. While you might see more adoption in offical/digital contexts, I just double checked a few popular spanish websites, all slashes.
