What is a Unix timestamp?

A Unix timestamp (or epoch time) is the number of seconds that have elapsed since January 1, 1970, 00:00:00 UTC. It is a simple, timezone-independent way to represent a point in time, widely used in APIs, databases, log files, and programming languages.

How to use it

To convert an epoch to a date, paste the timestamp into the left panel — the tool auto-detects whether it is in seconds or milliseconds. To convert a date to an epoch, pick a date and time in the right panel. Click the Now button to grab the current timestamp instantly.

Common use cases

• Debugging API responses that return timestamps.
• Reading log files with epoch-format dates.
• Converting database timestamps for reports.
• Calculating time differences between events.
• Setting cookie or token expiration times.
