Unix Timestamp Converter
Convert Unix timestamps (epoch) to human dates and back.
Turn a Unix timestamp into a readable UTC, ISO and local date — or go the other way and convert a date into its epoch value in seconds and milliseconds. Seconds and milliseconds are detected automatically, so you can paste either.
Frequently asked questions
What is a Unix timestamp?
The number of seconds (or milliseconds) that have elapsed since 1 January 1970 UTC, known as the Unix epoch. It is the standard way computers store a moment in time.
Does it handle milliseconds?
Yes. Values large enough to be milliseconds (13+ digits) are detected automatically, so both 1751200000 and 1751200000000 work.
Which time zone is used?
Results show UTC, ISO 8601, and your browser’s local time so you can read whichever you need.
