Frequently Asked Questions

How to convert a Unix timestamp to a date online?▾

What is a Unix timestamp?▾
A Unix timestamp (also called epoch time) is the number of seconds elapsed since January 1, 1970, 00:00:00 UTC. It is the standard way computers represent time internally.
What is the difference between seconds and milliseconds timestamps?▾
Timestamps in seconds are 10 digits (e.g., 1700000000). Millisecond timestamps are 13 digits (e.g., 1700000000000). JavaScript Date.now() returns milliseconds, while most Unix systems use seconds.
How to convert a date to Unix timestamp?▾
Select or enter your date and time, and the converter instantly outputs the corresponding Unix timestamp in both seconds and milliseconds format.
Does the converter handle time zones?▾
Yes. The converter displays results in both your local time zone and UTC, making it easy to debug timezone-related issues.
How to convert epoch time in JavaScript?▾
In JavaScript, use new Date(timestamp * 1000) for seconds or new Date(timestamp) for milliseconds. Our online tool provides the same conversion instantly without writing code.
Is this timestamp converter accurate?▾
Yes. The converter uses your browser's native Date API for precise conversions, correctly handling daylight saving time and timezone offsets.
