About the Unix timestamp converter

A Unix timestamp is the number of seconds since 1 January 1970 (UTC). This converter turns timestamps into readable dates and back again, which is indispensable for developers working with logs, APIs and databases that store time as a number.

Tips

  • Unix time counts seconds since the 1970 epoch in UTC.
  • Some systems use milliseconds — watch for an extra three digits.
  • Convert both directions: timestamp to date and date to timestamp.

Timestamp Converter — frequently asked questions

What is a Unix timestamp?
It is the number of seconds elapsed since midnight UTC on 1 January 1970, a compact way computers store dates and times.
Why is my timestamp off by a factor of 1000?
Many languages use milliseconds rather than seconds. Divide by 1000 to get the standard Unix timestamp.
Is Timestamp Converter free to use?
Yes. Timestamp Converter is completely free with no sign-up, no watermarks and no usage limits.
Is my data uploaded to a server?
No. Timestamp Converter runs entirely in your browser, so your data never leaves your device.
Is there a size limit?
Only your device's available memory — there are no server-side limits because nothing is uploaded.
