Frequently Asked Questions

What is a Unix timestamp?
A Unix timestamp is the number of seconds that have passed since January 1, 1970, 00:00:00 UTC (the 'epoch'). It's a common way for computers to store dates.
How do I get the current timestamp?
Click the 'Now' button to instantly fill in the current Unix timestamp, in both seconds and its human-readable equivalent.
Is my data uploaded anywhere?
No. The conversion happens entirely in your browser using JavaScript — no timestamps or dates are sent to any server, and the tool is completely free to use.
