What it does
The Timestamp Converter turns Unix timestamps into readable dates and dates back into timestamps. It detects whether a number is in seconds, milliseconds or microseconds, and shows the result in UTC, your local time, ISO 8601 and relative time.
How to use it
Timestamp → Date
- Paste a timestamp into Unix timestamp (s, ms or µs).
- Leave Unit on Auto, or choose Seconds, Milliseconds or Microseconds.
- Read the date in each format.
Date → Timestamp
- Type a date into Date / time (ISO, RFC or plain text), or use Pick.
- Copy the timestamp in seconds or milliseconds.
Examples
| Timestamp | Unit | Date (UTC) |
|---|---|---|
| 1792593000 | seconds | 21 Oct 2026, 14:30:00 |
| 1792593000000 | milliseconds | 21 Oct 2026, 14:30:00 |
| 0 | seconds | 1 Jan 1970, 00:00:00 |
Good to know
- Unix time counts seconds since 1 January 1970 UTC and ignores leap seconds.
- JavaScript, Java and many APIs use milliseconds (13 digits today); Unix tools, PHP and Python's
time.time()use seconds (10 digits). - Systems that store timestamps in signed 32-bit integers overflow on 19 January 2038.
FAQ
How do I get the current timestamp? The Current Date & Time page shows it live.
Why is my date off by some hours? The timestamp is UTC. The local time shown depends on your device's time zone.
