Unix Timestamp Converter
Convert Unix timestamps to human-readable dates and vice versa. Supports seconds and milliseconds.
Unix Time Basics
A Unix timestamp counts seconds, or milliseconds, since January 1, 1970 UTC. Developers meet both formats constantly: APIs often return milliseconds, while databases and command-line tools commonly use seconds. This converter detects the format, shows the UTC time, and gives you the local time for the same moment.
When You Need It
- Reading a timestamp from an API response or database log
- Generating a timestamp for a query parameter or cache key
- Converting a timestamp from another timezone before scheduling a task
Why does my timestamp show a different date?
Timestamps are absolute moments in time. The date changes only because your browser shows the same moment in your local timezone.
