How to use this tool
- Enter a Unix timestamp, or a date and time.
- It converts both directions automatically.
- Read the local time, UTC and Unix value.
What your result means
A Unix timestamp is the number of seconds since 1 January 1970 UTC — a compact, timezone-free way to store a moment. The tool shows it as your local time and UTC so you can line up logs and API responses.
Since 1 Jan 1970
The clock the whole internet counts by
A Unix timestamp is simply the number of seconds elapsed since midnight UTC on 1 January 1970 — the "epoch". Storing time as one integer sidesteps time zones, formats and languages, which is why databases and APIs love it.
There's a famous catch: 32-bit systems run out of room on 19 January 2038. Modern 64-bit systems push that limit billions of years away.
