Frequently Asked Questions

What is a Unix timestamp?
A Unix timestamp is the number of seconds elapsed since January 1, 1970 (UTC), known as the Unix epoch. It is a standard way to represent dates and times in programming.
How do I get the current Unix timestamp?
Click 'Use Now' to populate the current timestamp. In JavaScript, use Date.now() for milliseconds or Math.floor(Date.now()/1000) for seconds.
What is the difference between seconds and milliseconds timestamps?
Unix timestamps in seconds are 10 digits (e.g. 1700000000). JavaScript's Date.now() returns milliseconds, which is 13 digits. This tool auto-detects which format you're using.
