🕰️Unix Timestamp Converter
Convert Unix epoch timestamps to ISO/UTC dates and back. Millisecond timestamps are detected automatically; invalid dates are rejected with clear errors.

About this tool
The Unix epoch counts seconds since 1970-01-01T00:00:00Z. Convert epoch seconds (or milliseconds — detected automatically) to ISO 8601 dates, or parse any ISO date back into a timestamp.
ISO date = new Date(unixSeconds × 1000).toISOString() · seconds = floor(ms ÷ 1000)
Frequently asked questions
Is the Unix timestamp affected by time zones?
No — epoch time is absolute UTC. Time zones only matter when displaying the human-readable date.
Will timestamps stop working in 2038?
Only 32-bit signed systems overflow on 2038-01-19. Modern 64-bit systems (including this API) are unaffected for billions of years.
