Unix Timestamp Converter

Convert Unix timestamps to readable dates and back, right in your browser. Paste epoch seconds or milliseconds and see the local time, UTC, ISO 8601, RFC 2822, the relative "time ago" and even the Thai Buddhist year. Or pick a date and get its exact epoch seconds and milliseconds. A live ticker shows the current Unix time each second, and nothing is ever sent to a server.

How to use

Open the "Timestamp → date" tab and paste a Unix timestamp; the unit is auto-detected, or set seconds or milliseconds manually.
Read the local, UTC, ISO 8601, RFC 2822 and Thai Buddhist formats in the results table.
Switch the timezone selector between Local, UTC and Asia/Bangkok to see the same instant in each zone.
Use the "Date → timestamp" tab to pick a date and time and read its epoch seconds and milliseconds.
Click "Use now" or "Now" to insert the current time, then copy any value with one click.

Frequently asked questions

What is a Unix timestamp?

A Unix timestamp (or epoch time) is the number of seconds that have elapsed since 00:00:00 UTC on 1 January 1970, ignoring leap seconds. It is a simple, timezone-independent way to store a moment in time, used across programming languages, databases and APIs.

Is my timestamp in seconds or milliseconds?

Seconds-based timestamps are usually 10 digits, while millisecond timestamps are 13 digits. This converter auto-detects the unit by magnitude, but you can force seconds or milliseconds with the unit toggle if a value is ambiguous.

How do I convert a Unix timestamp to a date?

Paste the timestamp into the "Timestamp → date" tab. The tool instantly shows the local time, UTC, ISO 8601, RFC 2822 and Thai Buddhist date. Use the timezone selector to view the same instant in Local, UTC or Bangkok time.

How do I get the current Unix timestamp?

The live ticker at the bottom of the input panel shows the current Unix time in seconds and milliseconds, refreshing every second. Click Copy to grab it, or "Use now" to drop it straight into the converter.

Does this tool send my data anywhere?

No. Every conversion runs entirely in your browser using the built-in Date and Intl APIs. No timestamps or dates are uploaded, logged or stored on any server.
