Frequently asked questions
What is a Unix timestamp in seconds versus milliseconds?+
A Unix timestamp counts the time elapsed since January 1, 1970 UTC. Most systems store it in seconds, while JavaScript and many APIs use milliseconds, which are 1000 times larger. This converter detects and supports both.
How do I convert a Unix timestamp to my local time zone?+
Enter the epoch value and the tool shows both the UTC datetime and the local datetime based on your device clock and time zone settings, so you can read whichever you need.
How do I convert a date back into a Unix timestamp?+
Use the date and time picker. As you change the value the tool instantly shows the matching epoch in seconds and in milliseconds, ready to copy.
