About this tool
Turn a Unix (epoch) timestamp from a log file, database or API into a readable date in your local time, UTC and ISO 8601 — or convert a date and time back into a timestamp. Seconds and milliseconds are detected automatically, and the current Unix time updates live.
How to use it
- Paste a timestamp to see it as a date, or press “Convert this” to use the current time.
- To go the other way, pick a date and time and choose whether it's UTC or your local time.
- Copy the result you need.
Good to know
- Timestamps with 12 or more digits are treated as milliseconds; shorter ones as seconds.
- A Unix timestamp counts seconds since 1 January 1970 00:00:00 UTC and is the same everywhere in the world.
- Local time uses your device's time zone setting.
Frequently asked questions
What is a Unix timestamp?
The number of seconds that have passed since 1 January 1970 at midnight UTC. Programs use it because it's a single number that's easy to store and compare.
Why does my timestamp have 13 digits?
It's in milliseconds, which JavaScript and many APIs use. The converter detects this automatically.
