Convert Unix timestamps to dates online
This free Unix timestamp converter turns an epoch timestamp into a human-readable date and back again. Paste a timestamp to see it as your local time, UTC, and an ISO 8601 string, or pick a date to get its Unix timestamp — with the current epoch time ticking live at the top of the page.
How to convert an epoch timestamp
- Paste a Unix timestamp into the Timestamp → Date box. The converter auto-detects seconds or milliseconds, or you can set the unit yourself.
- Read the result as local time, UTC, and ISO 8601 instantly.
- To go the other way, pick a date and time in the Date → Timestamp panel to get the matching epoch value.
What is a Unix timestamp?
A Unix timestamp (or epoch time) is the number of seconds elapsed since 00:00:00 UTC on 1 January 1970. Because it is a single, timezone-independent number, it is the most reliable way to store and compare moments in time across systems.
Common uses
- Debugging APIs and logs — read
created_atorexpfields returned in JSON responses. - Database work — translate stored epoch columns into readable dates.
- Scheduling and expiry — check token, cache, or cookie expiry times.
Runs entirely in your browser
Every conversion is computed locally with JavaScript — nothing is uploaded or stored. Working with timestamps buried inside an API response? Pretty-print and explore the payload first with our JSON formatter and validator.
