Unix Timestamp Converter (Free Online)

Unix timestamp converter

In software, time is often stored as a Unix timestamp — a number of seconds since 1970 that humans cannot read. This tool converts a timestamp into a readable date-time in real time (showing local and UTC), converts a date back into a timestamp, and shows a live current timestamp.

How to use

Timestamp to date: enter a 10-digit (seconds) or 13-digit (milliseconds) timestamp to see the date instantly.
Date to timestamp: pick a date-time to get the matching Unix timestamp.
Copy the live number at the top whenever you need the current timestamp.

Common use cases

Debug time fields in APIs or logs.
Convert time ranges for database queries.
Check schedules and token expiry times.

Frequently Asked Questions

What is a Unix timestamp?

A Unix timestamp is the number of seconds elapsed since 1 January 1970 00:00:00 UTC. It is a time-zone-independent absolute time, widely used in code and databases.

How do I tell seconds from milliseconds?

A seconds timestamp is 10 digits, a milliseconds timestamp is 13 digits. The tool detects this automatically from the number of digits.

Which time zone is shown?

The tool shows both your device local time zone and UTC so you can compare them.

Does it need an internet connection?

Conversion runs entirely in your browser with no connection or upload; the current timestamp comes from your device clock.
