Frequently Asked Questions

What is a Unix timestamp?
The number of seconds since January 1, 1970, 00:00:00 UTC. Also called Unix epoch time. Widely used in databases, APIs, and log files because it's timezone-agnostic.
Seconds or milliseconds?
Both are common. JavaScript uses milliseconds (13 digits); most Unix systems and databases use seconds (10 digits). Our tool auto-detects based on length.
What about the year 2038 problem?
32-bit signed integers overflow at 2147483647 (= 2038-01-19 03:14:07 UTC). Modern systems use 64-bit timestamps which extend this to ~292 billion years. JavaScript is always 64-bit.
Does this handle timezones?
Yes. You can see the date in your local timezone OR UTC. The timestamp itself is always UTC — timezone only affects display.
Why start from 1970?
Historical reason — the Unix OS was designed in 1969 and developers picked the start of 1970 as "epoch zero". Been the standard ever since.
Is my data private?
100%. Conversion happens in your browser using Date and Date.now(). No server calls.
