How is it confusing? 15th of June to 15th of July.

People in some countries are accustomed to using a very weird mm/dd date format, probably that's the case here?

yyyy/mm/dd is the true format because its alphabetically sortable. dd/mm/yyyy is another sensible format because the units grow in size. mm/dd/yyyy is the insane one. Idk why the US persists with it tbh.

The true format is, of course, YYYY-MM-DD, not YYYY/MM/DD.

ye sorry.

It has flaws but it’s not “insane” or entirely illogical, it’s very clearly based on the way dates are spoken and written in English, ex. “Today is July 23rd, 2021”.

The reasoning is clear as day. However, even the English themselves do not use this broken format: https://en.m.wikipedia.org/wiki/Date_format_by_country

The US always seem to resist sensible things when it comes to units and formats: it is a mystery to me why they are so attached to imperial units, when the rest of the world sans Liberia and Myanmar are using metric units (and Myanmar planned to leave this shameful club before the recent coup).

I should have clarified that it is how dates are pronounced in American English. British people will say “it’s the 21st of July, 2021”.

I don’t think the US resisting things is so mysterious. The US is a large country that largely defines its own culture (and exports that culture to the world). The average american isn’t going to switch systems unless they have a VERY good reason to. For the fields where it matters (ex. the sciences) they’ve largely already switched.

It's not insane, but it's not very logical. As a non native speaker, I prefer to say "Today is the 23rd of July in 2021" which is perhaps not valid English.

imagine if 202 meant two hundred and twenty. Its insane.

Month day is not weird.

You should have mentioned something actually bad like month day year.

Sorry, it's standard in Europe, that's why I used it: 15th of June to 15th of July.

I meant the part to have the month twice.

It's the euro DD before MM style of date writing.

Oh, if the author just wrote DD.MM it's fine. I just don't understand why he wrote "June/July" afterwards.

It's Day/Month Day/Month I'm from Poland (Europe)

Sure, but I think it's more that it seems incredibly rare to write month/day without year in strictly numbers. In almost all cases i would write 15 Jun/15 Jul. I can't think of anytime i would intentionally write 15.06/15.07. We all know this is a global world. We all know conventions vary. We should aim to make things intuitive, not make people guess which convention 06.07 is using.

"rare" is subjective - I'd have written it the same way (DD.MM) if I were going to write those dates without thinking. The author is from Poland, and so am I. Old habits die hard.

Day.month is the standard throughout most of Europe.

And Latinoamérica.
