About this tool

Convert Unix timestamps to human-readable dates and times - and convert any date back to a Unix timestamp. Unix time is the number of seconds (or milliseconds) since 1 January 1970 UTC, used in server logs, APIs, databases, and nearly every programming language. This tool handles both seconds and milliseconds and shows the time in UTC and your local timezone.

2The tool automatically detects whether it's seconds or milliseconds based on the value.
3The equivalent date and time is shown in both UTC and your local timezone.

Frequently Asked Questions

What is a Unix timestamp?+

A Unix timestamp (also called epoch time or POSIX time) is the number of seconds elapsed since 00:00:00 UTC on 1 January 1970. It's a timezone-independent way to represent a moment in time.

How do I get the current Unix timestamp in JavaScript?+

Use Math.floor(Date.now() / 1000) for seconds, or Date.now() for milliseconds.

What is the Y2K38 problem?+

32-bit signed integers can only represent timestamps up to 2,147,483,647 - which corresponds to 03:14:07 UTC on 19 January 2038. Systems using 32-bit timestamps will overflow on that date. Modern systems use 64-bit integers to avoid this.

Is a Unix timestamp always in UTC?+

Yes. Unix time is always measured from UTC epoch. The tool also shows the equivalent time in your local browser timezone for convenience.
