Timestamp Converter
Convert Unix timestamps to dates and back.
Conversions run in your browser using your device clock and time zone — nothing is sent to the server.
About Timestamp Converter
The Timestamp Converter translates Unix timestamps into human-readable dates and back, entirely in your browser. A live clock shows the current Unix time in both seconds and milliseconds, and every conversion uses your device’s clock and time zone — nothing is sent to a server.
Feed it an epoch value and you get the moment expressed five ways: ISO 8601 in UTC, plain UTC, your local time, RFC 2822 and a relative phrase like “3 hours ago”. Millisecond timestamps (13 digits) are recognized automatically, so values copied from JavaScript or log files just work.
The reverse direction is just as quick: enter a date and time to get the corresponding Unix timestamp in seconds and milliseconds. Every output line copies to the clipboard with a single click, and a “Use now” shortcut drops in the current moment.
How to use Timestamp Converter
- Glance at the live current Unix time, shown in seconds and milliseconds.
- Paste an epoch value — 10-digit seconds or 13-digit milliseconds are both detected.
- Read the result as ISO 8601 (UTC), UTC, local time, RFC 2822 and a relative phrase.
- For the reverse, enter a date and time to get its Unix timestamp in seconds and milliseconds.
- Click any output line to copy it.
