It warms my heart to see so many comments in the camp of “I use it everywhere”. Absolutely same here. You are my people.

I’m definitely in the “for almost everything” camp. It’s less ambiguous especially when you consider the DD/MM vs MM/DD nonsense between US dates vs elsewhere. Pretty much the only time I don’t use ISO-8601 is when I’m using non-numeric month names like when saying a date out loud.

better than the absolutely deranged MM/DD/YYYY and imo the best when it comes to international communication

There are two ways of writting dates: the “yyyy-mm-dd” one and the wrong one
