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.
