How it works
Unix time counts seconds since 1 January 1970 00:00:00 UTC. Paste a timestamp in seconds, milliseconds, microseconds or nanoseconds: the converter guesses the unit from the number of digits (10 for seconds, 13 for milliseconds) and shows the date in UTC, your local time and ISO 8601. Or pick a local date and time to get its timestamp.
Questions and answers
What is a Unix timestamp?
The number of seconds since the Unix epoch, 1970-01-01T00:00:00Z, ignoring leap seconds. JavaScript and many APIs use milliseconds instead.
How do I tell seconds from milliseconds?
Present-day timestamps have 10 digits in seconds and 13 in milliseconds. ConvertEasy detects this automatically.
What is the year 2038 problem?
Signed 32-bit timestamps overflow on 19 January 2038 at 03:14:07 UTC. 64-bit systems and JavaScript are unaffected.
