Unix Timestamp Converter

How to Use the Timestamp Converter

The tool shows the current Unix timestamp in real time. Enter a timestamp in the left panel to convert it to a human-readable date — the tool automatically detects seconds (10 digits) or milliseconds (13 digits). Use the right panel to pick a date and get the corresponding Unix timestamp. Select a timezone to see the date in any region.

What Is a Unix Timestamp?

A Unix timestamp (also called epoch time or POSIX time) counts the number of seconds that have elapsed since January 1, 1970, 00:00:00 UTC. This simple integer format is used universally in programming because it is timezone-independent, easy to compare, and compact to store. Most programming languages, databases, and APIs use Unix timestamps internally. JavaScript uses millisecond timestamps (13 digits), while most other systems use seconds (10 digits).

Common Use Cases

Debug API responses that return timestamps. Convert database timestamps to human-readable dates. Calculate the time difference between two events. Verify JWT token expiration times with our JWT Decoder. Schedule recurring tasks with our cron expression generator. Convert between timezones for scheduling across regions. Generate unique identifiers with the UUID generator. Check if a cached value has expired based on its timestamp. The relative time display shows how far in the past or future a timestamp is from right now.
