Tell me, please, how does the average US American react to dates written like 2021-01-24? Having spent far too much of my life using computers to sort and otherwise disentangle dates, I now write it everywhere I'm not specifically required t use another format. Everyone (i.e. ordinary folk) seems to accept it without comment here
I've seen British people confused by 2021-01-24 style dates, it takes some people several minutes to work it out.
Yep, I really don't understand how we started using format month/day/year as apposed to most others year/day/month. If you are involved in international activities you're used to it....like airline pilots for example. But the average Joe Dirt can be very much confused by it and show up for an appointment in the wrong month.
Now you're being confused by it. The standard British, and most European country's way of writing the date is year/month/day, not "year/day/month" as you've written.
The ISO date format (YYYY-MM-DD) is, IMNSHO, superior in every regard to all the other ways of writing the date, not least because it has a natural monotonic sorting order if just treated as a decimal number (ignoring the punctuation).
In other news. We're getting what nowadays passes for snow in London. Hardly worth the weather even
bothering if that's all it's going to do.
