My routine date usage drives my fellow Americans sorta nuts. In any written-out version, unless the medium forces otherwise, it's always [numeric date] [alpha month, either fully written or 3-letter abbreviation] [full numeric year]. I get kidded all the time about writing "6 Jan 2020" rather than "1/6/2020."
With non-displayed code and in document naming conventions, I always use year-month-day, as in either 2020-01-06 or the numeric-only version 20200106: largest element first, second largest second, smallest last, all in consistent positions in a field. Because that way computers, when alpha-sorting, always place the items in correct ascending chronological order, to the day. I appreciate that some companies like Family Tree DNA use the same convention, [KitNumber]_SNPs_20200106.csv.
Drives me nuts that things like the Apache web server software saves log files by the default something.com-Jan-2020...all the same months are grouped together in alphabetical order and you have to go hunting for the correct year.
