Convert Unix timestamps to readable dates and back, with local time, UTC, ISO 8601, and relative time. Includes a live current timestamp clock for quick reference.
Start convertingUnix timestamps represent a single moment in time as the number of seconds (or milliseconds) since January 1, 1970 UTC. This tool converts a timestamp into a readable date in your local timezone, in UTC, and in ISO 8601 format, and can also convert any date back into a Unix timestamp.

A Unix timestamp is the number of seconds (or milliseconds) that have elapsed since 00:00:00 UTC on January 1, 1970, commonly called the Unix epoch.
A 10-digit number is typically seconds, while a 13-digit number is typically milliseconds. Most Unix systems use seconds, while JavaScript's Date.now() returns milliseconds.
A Unix timestamp represents one exact instant in time. Local time shows that instant using your device's current timezone setting, while UTC shows the same instant with no timezone offset applied.
ISO 8601 is a standardized date and time format, such as 2026-07-31T12:00:00.000Z, that is unambiguous across systems and widely used in APIs and log files.
Yes. Use the date-to-timestamp section to pick any date and time and get the matching Unix timestamp in both seconds and milliseconds.
No. All conversions happen locally in your browser using client-side JavaScript. Nothing you enter is sent to a server.
