While I am a strong supporter of ISO8601 (e.g. 2023-07-12) there is an argument that decreasing specificity is preferable (as in ISO8601) and that for most day-to-day usage the year is somewhat implicit, hence being at the end.

Personally, I write the month out if I'm not using 8601 formatting to avoid any ambiguity.

For any sort of recordkeeping, though, I think it's preferable to go full on YYYY-MM-DD. It's more thorough, precise, and sorts properly on a computer.
