- Convert a Unix timestamp to a dateA Unix timestamp identifies one instant relative to 1970-01-01T00:00:00Z. Choose seconds or milliseconds explicitly, then select a timezone to display that same instant as a local civil date and time.
- Convert a date to a Unix timestampA local clock reading does not identify an instant until a timezone is supplied. This guide shows how the converter applies the selected IANA timezone and handles daylight-saving transitions.
Frequently Asked Questions
What is a Unix timestamp?
A Unix timestamp (also called epoch time) is the number of seconds that have elapsed since January 1, 1970, 00:00:00 UTC. It's a standard way to represent time in computer systems and is commonly used in programming and databases.

How do I convert a date to a Unix timestamp?
Select or enter a date and time using the date picker, choose your timezone, and click 'Convert to Timestamp'. The tool will display the Unix timestamp (in seconds) for that date and time.
What timezone does the Unix timestamp use?
Unix timestamps are always in UTC (Coordinated Universal Time). However, our converter allows you to view and input dates in any timezone. The conversion automatically handles timezone differences.
Can I convert timestamps in milliseconds?
Yes. Select s for seconds or ms for milliseconds before converting. The converter never guesses the unit from the size of the number.
