Timestamp Converter
Convert between a Unix timestamp and a readable date, both directions.
What a Unix timestamp is
A Unix timestamp counts the seconds elapsed since 00:00:00 UTC on 1 January 1970. It's timezone-independent by design — the same number always refers to the same instant everywhere, which is why it's the standard way computers store and compare dates internally.
About the Timestamp Converter
Timestamp Converter converts a Unix timestamp to a readable date and a date to a timestamp, showing both your local time and UTC. Developers use it when working with logs, databases and APIs.
A Unix timestamp is the number of seconds since 1 January 1970 00:00:00 UTC. Some systems use milliseconds, which are 1000 times larger, so a 13-digit value is usually milliseconds while a 10-digit value is seconds. Timestamps are independent of time zones; only the displayed date changes with the zone.
How to use it
- Enter a Unix timestamp in seconds and press Timestamp → Date.
- Or choose a date and time and press Date → Timestamp.
- Read local time and UTC.
- Copy the value you need.
Tips and good to know
- If a date looks like the year 50000, you probably entered milliseconds.
- Store times in UTC and convert for display.
- Daylight saving changes affect local time only.
Frequently asked questions
What is epoch time?
Another name for Unix time.
Can I enter milliseconds?
Divide by 1000 first.
What happens in 2038?
Systems using 32-bit signed seconds overflow; modern systems use 64 bits.
