About the Unix Timestamp Converter
A Unix timestamp is the number of seconds (or milliseconds) since 1 January 1970 UTC — the way computers and APIs almost always store time. It's compact and timezone-free, but impossible for a human to read at a glance. This converter translates between Unix timestamps and normal, readable dates in both directions.
Enter a timestamp to see the human date, or pick a date to get the timestamp. Conversions happen instantly in your browser, with both UTC and your local time shown.
How to use it
- 1To read a timestamp, paste the Unix value into the input.
- 2The tool shows the matching date and time in both UTC and your local timezone.
- 3To go the other way, enter a human date and get its Unix timestamp.
- 4Switch between seconds and milliseconds depending on what your system uses.
- 5Copy the result into your code, database query or log analysis.
Common uses
- →Turning a timestamp from a log file or API response into a readable date.
- →Getting the Unix value for a specific date to use in a query.
- →Debugging time-related bugs by checking exactly when an event happened.
- →Converting between UTC and local time for scheduling.
- →Checking token or cache expiry times stored as timestamps.
Tips & good to know
- Watch the units: JavaScript uses milliseconds, most backends use seconds — a 1000x difference.
- Unix timestamps are always in UTC; apply a timezone offset only when displaying to users.
- The current timestamp is handy for setting created-at or expiry values.
Frequently asked questions
- Seconds or milliseconds?
- Both are supported. Unix timestamps are classically in seconds, but JavaScript and some APIs use milliseconds (1000x larger). The tool lets you switch.
- Does it handle timezones?
- Yes. Timestamps are UTC-based, and the tool shows both UTC and your local time when converting.
- Is anything uploaded?
- No. All conversions run locally in your browser.
