Timestamp Converter - Unix Time to Human Date & Back

In short: the Timestamp Converter turns Unix epoch numbers into readable dates - in UTC, your local timezone and as relative time like "3 days ago" - and converts dates back into timestamps, with the current timestamp ticking live at the top.

Log files, APIs and databases speak in Unix timestamps: 1762329600 means nothing to a human until it is a date. This converter translates both directions instantly, handles seconds and milliseconds, and shows the current epoch time updating live for quick reference.

Timestamp to date

Date to timestamp

Private by design: everything in this tool happens 100% in your browser with JavaScript. Your input is never uploaded to a server, never stored and never seen by us - close the tab and everything is gone.

How to use the Timestamp Converter

  1. For a timestamp: paste it, pick seconds, milliseconds or auto-detect, and click Convert to Date.
  2. For a date: type it in the lower box and click Convert to Timestamp.
  3. Read the result in UTC, your local time, ISO format and relative terms.

How it works

A Unix timestamp counts the seconds (or milliseconds) since 1 January 1970, 00:00:00 UTC - the "epoch". Because it is just a number, it is unambiguous worldwide; the confusion starts when humans need a calendar date and a timezone. This tool does the arithmetic with your browser's date engine: the same instant is shown in UTC, in your device's timezone and in ISO 8601 form, plus a relative phrase. Auto-detect treats very large numbers (13 digits) as milliseconds and typical 10-digit numbers as seconds - the two shapes used by virtually every real system.

Worked example

The timestamp 1794441600 converts to Thursday, 12 November 2026, 00:00 in UTC - and if your device is in Pakistan it shows the same moment as 05:00 local time, because Pakistan is UTC+5. Same instant, two correct readings - which is exactly why timestamps exist.

Frequently Asked Questions

Is this timestamp converter free?

Yes - free, with no sign-up and no limits.

Seconds or milliseconds - how do I know?

Seconds timestamps are currently 10 digits (around 1.7 billion); milliseconds are 13 digits. Auto-detect uses that rule; you can also force a unit.

Why do UTC and my local time differ?

They are the same instant expressed in different timezones. Databases usually store UTC; the local reading depends on where your device is.

What dates can it handle?

Any date the browser's date engine supports - far beyond the famous 2038 limit of old 32-bit systems, which applies to those systems, not to this converter.

Is anything uploaded?

No - all conversions happen in your browser.
