Frequently Asked Questions

How do I identify an unknown date format?

Paste the date string into the detector. It tests against all common formats (ISO 8601, RFC 3339, Unix timestamp, SQL datetime, hex timestamp) and reports which ones match.

Can the detector handle ambiguous date strings?

Yes, it shows all matching interpretations. For example, "01/02/2024" could be January 2nd (US) or February 1st (EU) — both are reported.
