Handy for
Reading log times, API values and database timestamps.
Good to know
A Unix timestamp counts seconds since 1 January 1970 UTC. JavaScript and many APIs use milliseconds instead.
Privacy: where the work happens
Everything you enter or choose is processed by JavaScript in your browser and never sent anywhere. Only the page code, and any library this tool needs, is downloaded from cdnjs or jsDelivr.
Questions
Seconds or milliseconds?
Numbers below 100 billion are read as seconds and larger ones as milliseconds.
Which time zone is used?
UTC is shown, plus your own local time. A date without a time, such as 2026-01-31, is read as UTC.
