Frequently asked questions
Is this timestamp converter free?

What is a Unix timestamp?
The number of seconds since January 1, 1970, 00:00:00 UTC (the "Unix epoch") — a common way to store dates in databases and APIs.
Does it support milliseconds?
The main input is seconds (the standard Unix timestamp), but the results also show the equivalent value in milliseconds for convenience.
Is my data sent to a server?
No. All conversion happens locally in your browser.
