Timestamp Converter

About the Unix Timestamp Converter

A Unix timestamp counts the seconds (or milliseconds) since 1 January 1970 UTC. Paste one to see it as a readable date in UTC and in your local time zone, or pick a date to get its timestamp. Seconds and milliseconds are detected automatically.

How to use it

1. Enter a Unix timestamp, in seconds or milliseconds, to see the date.
2. Or choose a date and time to get its Unix timestamp.
3. Read the result as UTC, local time, ISO 8601 and more.
4. Copy the format you need.

Features

Frequently asked questions

How do I tell seconds from milliseconds?

A current timestamp in seconds has 10 digits (about 1.7 billion) and in milliseconds has 13 digits. The tool treats very large values as milliseconds and smaller ones as seconds.

What is the Unix epoch?

The epoch is the starting point, 00:00:00 UTC on 1 January 1970. A Unix timestamp is the number of seconds elapsed since then, ignoring leap seconds.

Why is the local time different from UTC?

UTC is the same everywhere. Local time applies your device's time zone offset, including daylight saving, so the same timestamp shows different clock times in different places.
