ISO 8601 RFC 3339 (yyyy-mm-dd) for storing dates in software. Any format that that goes in the order of day, month, and year for conversational/presentational purposes, preferable the format is dynamic depending on the user's locale (even for those that want the month first). There now everyone is happy.

Edit: switched to RFC 3339 since it is a subset of ISO 8601 that is more strict, and I love semantics.

    RFC3339 is better than ISO8601 since it doesn't allow some of the esoteric formats, and allows some useful formats that ISO8601 doesn't (like separating date and time by a space instead of by T)

    For example, 2026-W32-1 is also a valid ISO8601 date: Monday on the 32nd week of 2026. That format isn't allowed with RFC3339.

    Damn it I forgot about the duration part of ISO 8601 (which is also super useful and I love it). I'll amend it to RFC 3339 to be more exact in what I mean (even though the specified format should prevent the more esoteric formats).
