About this tool
Logs, APIs and databases speak Unix time — seconds since 1 January 1970 UTC. Paste a timestamp to see the date in UTC and your local time, or pick a date to get its timestamp. Second and millisecond inputs are auto-detected, and a live "now" counter is one click away.
Everything runs locally in your browser — nothing is uploaded, logged or stored.
How to use
- Paste a timestamp on the left, or pick a date on the right.
- Read the conversion instantly.
- Use the live "now" value when you need the current timestamp.
