Unix Timestamp Converter

Unix timestamps count seconds (or milliseconds) since January 1, 1970 UTC — the format most APIs, logs, and JWTs use for dates. This tool converts between epoch time and readable dates in any timezone.

Frequently Asked Questions

Is a JavaScript timestamp in seconds or milliseconds?: JavaScript's Date.now() returns milliseconds; most other languages/APIs use seconds — check which your source uses.
