Frequently asked questions
What is a Unix timestamp?
A Unix timestamp (epoch) is the number of seconds elapsed since January 1, 1970 00:00:00 UTC. It's widely used in programming as a universal time format.
Does this support milliseconds?
The converter expects seconds. For milliseconds (common in JavaScript), divide by 1000 first — or paste the value and it will handle 13-digit ms timestamps automatically.
What is the current Unix timestamp?
Click "Now" to get the current timestamp. The current value updates each time you click.
What is the maximum Unix timestamp?
The 32-bit Unix timestamp max is 2,147,483,647 (January 19, 2038) — the "Year 2038 problem". 64-bit systems extend this far into the future.
Is this free?
Yes, completely free with no signup required.
Are my timestamps stored?
No — all conversions run in your browser using the JavaScript Date API. Nothing is transmitted.
