What is a Unix timestamp?

A Unix timestamp is the number of seconds (or milliseconds) elapsed since January 1, 1970 00:00:00 UTC (the Unix Epoch). It's the standard way most programming languages and databases represent points in time.

Does it support millisecond timestamps?

Yes. The tool auto-detects whether a timestamp is in seconds (10 digits) or milliseconds (13 digits) and converts accordingly. You can also manually select the unit.

Can I convert to a specific timezone?

Yes. Select any IANA timezone (e.g., America/New_York, Europe/London) from the dropdown and the converted datetime is shown in that timezone's local time.

What is the Unix Epoch?

The Unix Epoch (January 1, 1970 00:00:00 UTC) is the reference point for Unix timestamps. It was chosen as a convenient round number for early Unix systems and has become the universal computing standard.
