Frequently Asked Questions
What is a Unix timestamp?
A Unix timestamp is the number of seconds that have elapsed since the Unix Epoch (January 1, 1970, at UTC).
How do I convert a timestamp to local time?
Paste the timestamp into the converter. It instantly translates it to UTC and your local time zone.

Why does Unix time start at 1970?
January 1, 1970, was chosen arbitrarily as the epoch reference point for early Unix operating systems.
How does daylight savings time affect conversions?
The tool uses your browser's local time zone offsets, which automatically adapt to daylight savings rules.
