American software engineers use ISO8601 or RFC3339 ... I just wrote 20210108 in my journal this morning (referring to a podcast episode published yesterday).

I'll admit I might be annoying to others ... my wife is specifically irritated when I write a time in military format (but my son has no problem reading it from my phone).

I do that too, but I often replace the month with the 3 letter abbreviation to make it easier for others.

E.g. 2021JAN08.
