What is a UNIX timestamp?

A UNIX timestamp (also called epoch time or POSIX time) counts the seconds since January 1, 1970 at 00:00:00 UTC. It is timezone-independent by design: the number 1716480000 represents the same moment whether you are in New York, London, or Tokyo.

UNIX timestamps appear throughout software: in database records, API responses, log files, and system clocks. Because they are simple integers, they sort and compare efficiently. The challenge is reading them: a raw number like 1716480000 means nothing without conversion.

This tool converts any UNIX timestamp (seconds, milliseconds, or microseconds), ISO 8601 date string, or standard date format into human-readable times. Select one or more IANA timezones to compare the same instant across regions. All conversions happen in your browser: no data is sent anywhere, no cookies are set, no analytics track your usage.

Frequently asked questions

How do I convert a UNIX timestamp to a date?

Paste your timestamp in the input above. The tool auto-detects whether it is in seconds (10 digits), milliseconds (13 digits), or microseconds (16 digits). Select your target timezone and the converted date appears instantly. You can add multiple timezones for side-by-side comparison.

What is the difference between UNIX seconds and milliseconds?

UNIX timestamps in seconds are 10-digit numbers (for example, 1700000000 for November 14, 2023). In milliseconds they are 13-digit (1700000000000). The tool handles both automatically, and also supports 16-digit microsecond timestamps.

Which timezones are supported?

All IANA timezones, typically 400+. This includes UTC, US timezones (Eastern, Central, Mountain, Pacific), European (London, Paris, Berlin), Asian (Tokyo, Shanghai, Singapore, Kolkata), and many more. Use the search field to find yours.

Is my timestamp sent to a server?

No. Everything runs in your browser using the JavaScript Internationalization API. Your input never leaves your device. The page works offline once loaded.

Can I share a conversion?

Yes. The URL updates automatically with your timestamp and selected timezones. Copy and share the link: opening it restores the exact same conversion for the recipient.
