Convert Time to Epoch
Convert time to epoch for 2026 API tests, SQL inserts, JWT expirations, cron windows, and log replay workflows. Enter a date and clock time, pick the intended timezone, and copy the exact Unix timestamp in seconds or milliseconds.

When to convert time to epoch
Teams usually need date-to-epoch conversion while preparing API payloads, debugging token expirations, or matching application events against database records. A readable wall-clock time like 2026-03-27 09:30:00 is useful for humans, but backend systems often want a Unix integer instead. Converting that input into epoch seconds or milliseconds removes formatting ambiguity before the value reaches production code.
Timezone is the critical step
The same local clock reading can represent different UTC instants depending on timezone. That is why this page keeps timezone selection above the converter. If a product manager sends a launch time in Los Angeles but your server stores UTC, converting with the wrong timezone can shift the epoch output by seven or eight hours. Always confirm the source timezone before you generate the final Unix value.
Seconds vs milliseconds
Most SQL functions, JWT claims, and infrastructure tooling expect 10-digit epoch seconds. Frontend code and browser telemetry often expect 13-digit milliseconds instead. This converter returns both outputs together so you can paste the right unit without doing manual math or risking a 1000x timestamp bug.
