Frequently Asked Questions

What is a Unix timestamp?
A Unix timestamp (also called Epoch time or POSIX time) is the number of seconds that have elapsed since January 1, 1970 at 00:00:00 UTC. It is widely used in programming and databases to represent a specific point in time as a single integer value.
What is the difference between seconds and milliseconds timestamps?
A seconds-based Unix timestamp is a 10-digit number representing seconds since the Unix epoch. A milliseconds-based timestamp is a 13-digit number that includes three extra digits for millisecond precision. JavaScript and Java commonly use milliseconds, while PHP and Python typically use seconds.
How do I convert a date to a Unix timestamp?
Use the date input field on this page to select your desired date and time. The tool will instantly calculate the corresponding Unix timestamp in both seconds and milliseconds. You can then copy the result with one click.
Is my data safe?
Yes! All processing happens entirely in your browser. Your data is never sent to any server. No data is collected, stored, or transmitted.
What output formats are supported?
This tool displays the converted result in four formats: ISO 8601 (e.g. 2024-01-15T09:30:00.000Z), UTC string, your local time zone format, and a relative time description such as "2 hours ago" or "in 3 days".
