Frequently asked questions
What is a Unix timestamp?
A Unix timestamp counts the number of seconds (or sometimes milliseconds) that have passed since January 1, 1970, 00:00:00 UTC — often called "the epoch." It’s a time zone-independent way to represent a specific moment in time.
How do I know if my timestamp is in seconds or milliseconds?
Unix timestamps in seconds are 10 digits for dates in the current era (e.g. 1735689600); in milliseconds, they’re 13 digits (e.g. 1735689600000). Use the toggle to switch units if your result looks wildly wrong.
Is my data saved anywhere?
No. Every conversion happens locally in your browser using your device’s clock and time zone data — nothing is transmitted or stored.
