About the Timestamp Converter
Unix timestamps count seconds since 1 January 1970 and appear throughout logs, databases and APIs. This free timestamp converter translates between Unix epoch and human-readable dates in both directions, in seconds or milliseconds, and is timezone-aware.
It runs in your browser.
How to convert timestamps
- Enter a Unix timestamp to see the human date, or pick a date to get the timestamp.
- Switch between seconds and milliseconds.
- See both UTC and your local time.
Where Unix time comes from
Unix time counts seconds from midnight UTC on 1 January 1970 — the "epoch" — chosen when Unix was being developed. It ignores timezones and (for practical purposes) leap seconds, which makes it a compact, unambiguous way to store a moment. One historical caveat: 32-bit signed timestamps overflow in January 2038, so modern systems use 64-bit values.
Frequently asked questions
What is a Unix timestamp?
The number of seconds (or milliseconds) elapsed since 00:00:00 UTC on 1 January 1970, a compact, timezone-free way to represent a moment in time.
Seconds or milliseconds?
Unix timestamps are traditionally in seconds (10 digits today), but JavaScript and many APIs use milliseconds (13 digits). The tool handles both.
Does it account for timezones?
Yes. It shows the converted time in both UTC and your local timezone.
Why does my converted time look an hour off?
Almost always a timezone or daylight-saving difference. A Unix timestamp is always UTC; the human date you compare it to may be in local time. This tool shows both UTC and your local time so you can see the offset.
