I write the date a bit different depending on which format its going on.
For example, computers like to sort things alphabetically. If I'm writing electronic diary entries, I'll name the document as "2025-06-01."
If I'm hand signing a legal document, I prefer to sign it as "01JUN2025" or "01JUN25" if space is an issue.
If the format is preselected and deviation isn't allowed, I'll just write it like everyone else does.
Personally, I like dating things in ascending or descending order. Day month year, or year month day.
