What is a Unix Timestamp Converter?

A Unix timestamp converter turns a Unix timestamp into a readable date and converts a date back into Unix time. Unix time counts elapsed time from January 1, 1970 at 00:00:00 UTC.

This converter supports timestamps in seconds and milliseconds. It shows UTC time, browser-local time, ISO 8601, RFC 2822, and the equivalent Unix seconds and milliseconds.

Seconds vs Milliseconds

Unix timestamps often appear in seconds, such as 1778112000. JavaScript dates and many API logs often use milliseconds, such as 1778112000000. The same instant can be represented either way, so checking the unit matters.

Timestamp Converter Use Cases

  • Read timestamps from logs, API payloads, databases, and webhook events.
  • Convert a planned date into Unix seconds for configuration.
  • Compare UTC time with the local browser timezone.
  • Verify whether a timestamp is in seconds or milliseconds.

For API payload cleanup, use the JSON Formatter. For encoded values in logs, use the Base64 Encoder Decoder.
