Epoch Converter

Type a Unix timestamp or a date, and read the whole calendar breakdown back. Named timezones are handled honestly: a local time that never happened, or happened twice, is shown rather than guessed.

This is generated in browser and is not sent to pah.moi servers.

The Epoch Converter needs JavaScript to convert timestamps in your browser. It is client-only. Everything here is available offline via the epoch-cli command-line tool, including named timezones (--tz), the other units (--unit) and the difference between two timestamps (--diff). Running epoch-cli with no argument prints the accepted input shapes.

About this tool1 paragraph

Convert a Unix timestamp (seconds, milliseconds, microseconds or nanoseconds, decimal or hex) to a calendar breakdown, or go the other way from an ISO 8601 / RFC 3339 date or a plain date. The field takes six shapes, all of which name 2023-11-14T22:13:20Z or the day around it: 1700000000, 0x6553F100, 2023-11-14T22:13:20Z, 2023-11-14 22:13:20, 2023-11-14 22:13, and 2023-11-14. A date with no offset is read as a wall-clock time in the timezone you pick, so a bare date is midnight there. See UTC and local side by side, and pick a named IANA timezone. You also get RFC 2822 and RFC 3339 lines, the ISO week number, a relative time ("three days ago"), a warning when a timestamp is near the 2038 limit, and the exact gap between two timestamps.
