> It's the most obnoxiously American attitude imaginable to ignore this issue because it doesn't affect them... only the other 96% of the planet.

I’m not going to comment on the author, though I will acknowledge the abrasive, unhealthy attitude.

Anyway, no. I don’t think there’s a clear “American” standard. Maybe there once was, but I’d just see a pile of numbers these days. It’s hostile to the consumer as it inherently leaves some uncertainty of how it should be consumed.

I will say, and maybe this is American - but I don’t think it is - that I often see dates formatted unambiguously as, e.g. March 11, 2021.
