Epoch & Unix Timestamp Converter
Convert Unix timestamps to human-readable dates and back — free, with a live current epoch, automatic seconds/milliseconds detection and UTC + local output.
100% private — runs entirely in your browser. Nothing you enter is uploaded or logged.
Unix time counts seconds since 1 Jan 1970 UTC. A 13-digit value is milliseconds; a 10-digit value is seconds — this tool detects which automatically. All conversions happen locally.
How to use the Epoch & Unix Timestamp Converter
- Copy the live current Unix time if you need it.
- Paste a timestamp to see the date (UTC + local).
- Or pick a date to get its timestamp.
- Seconds vs milliseconds is detected automatically.
What you can use it for
- Convert Unix timestamps to readable dates
- Get the epoch for a specific date/time
- Debug API timestamps in seconds or milliseconds
- Check relative time (ago / from now)

What is the current Unix timestamp?
It's the number of seconds since 1 January 1970 UTC — this tool shows it live, updating every second.
How do I tell seconds from milliseconds?
A 10-digit value is seconds and a 13-digit value is milliseconds — the converter detects which automatically.
How do I convert an epoch to a readable date?
Paste the timestamp and it shows the UTC, local, ISO-8601 and relative (e.g. '3 days ago') versions.
What is the Year 2038 problem?
32-bit systems store Unix time in a signed 32-bit integer that overflows in January 2038; 64-bit timestamps avoid it.
How do I get the timestamp for a specific date?
Use the date picker — it returns both the seconds and milliseconds value for that local date and time.
