Unix Timestamp Converter

Convert a Unix timestamp to a readable date and time in your local timezone, UTC, and any timezone you pick. Runs entirely in your browser.

How it works

EpochClock reads the number you paste, figures out whether it's in seconds or milliseconds based on its size, and formats it in three ways at once: your browser's local timezone, UTC, and any timezone you pick from the dropdown. The reverse converter below does the opposite — pick a date, time, and timezone, and get the matching Unix timestamp. Everything runs locally using your browser's built-in timezone data; nothing is sent to a server.

Frequently asked questions

Is this free to use?

Yes. There's no sign-up and no limit on how many conversions you run.

Does it work with milliseconds as well as seconds?

Yes. It automatically detects whether the number you paste is in seconds or milliseconds based on its size.

Can I convert a date back into a timestamp?

Yes. The second section on the page takes a date and time in a timezone you pick and gives you the matching Unix timestamp in both seconds and milliseconds.

Do you store the timestamps I convert?

No. All conversion happens locally in your browser using its built-in timezone data, and nothing is uploaded or stored.
