Worked example
The Unix timestamp 1735689600 corresponds to 00:00:00 UTC on 1 January 2025.
Assumptions
- Treats the entered value as seconds since the epoch, not milliseconds.
- Local time shown uses your browser's time zone setting.
How this calculator works
Convert a Unix epoch timestamp into a readable date and time, or generate the timestamp for the current moment — a handy reference when reading logs, APIs or database records.
Frequently asked questions
What is a Unix timestamp?
It's the number of seconds that have elapsed since midnight UTC on 1 January 1970, widely used by computer systems to store dates.
Does this show my local time zone?
It shows the equivalent UTC time and your browser's local time so you can check both.
Why do some systems use milliseconds instead of seconds?
Some languages and APIs (like JavaScript's Date) use milliseconds since the epoch; divide by 1000 to get the standard seconds-based timestamp.
