Unix timestamp converter

0 is the Unix epoch, midnight UTC on 1 January 1970. 2147483647 is the last second a signed 32-bit number can hold, the "year 2038 problem" for old systems.

Count the digits. Today’s timestamps are 10 digits in seconds (Unix, PHP, Python’s time.time) and 13 in milliseconds (JavaScript’s Date.now, Java). The page guesses the unit from the size and says which it used.

1. Paste a timestamp, or type a date such as 2026-11-04T09:30.
2. Read it in every format, and copy the one you need.
3. Pick a time zone to see the same moment there.

What is a Unix timestamp?

The number of seconds since 00:00:00 UTC on 1 January 1970, not counting leap seconds. It’s the same everywhere in the world at the same moment.

Does a timestamp have a time zone?

No. It’s a moment, not a clock time. Time zones only come in when you show it as a date, which is why this page shows UTC, your time and any zone you pick.

How do I get the current timestamp?

It’s at the top of the page, live, in seconds and milliseconds. In code: Math.floor(Date.now() / 1000) in JavaScript, time.time() in Python, date +%s in a terminal.
