Unix Timestamp Converter
Convert between Unix timestamps and human-readable dates. Supports seconds and milliseconds.
—About This Tool
The Unix Timestamp Converter converts Unix timestamps to human-readable dates and times, and converts any date back to a Unix timestamp. It supports both second-precision (10-digit) and millisecond-precision (13-digit) timestamps and displays results in your local time zone.
A Unix timestamp (also called Epoch time) counts the number of seconds elapsed since January 1, 1970 00:00:00 UTC. It is the standard time representation in most programming languages and APIs because it is timezone-independent and trivially comparable.
How to Use
- Click Get Now to see the current Unix timestamp.
- To convert a timestamp to a date: enter the timestamp in the top field and click Convert.
- To convert a date to a timestamp: use the date/time picker in the bottom section and click Convert.
- The result shows the date in both local time and UTC.
Use Cases
Backend developers inspect API responses that return timestamps to debug timing issues. Database administrators convert stored epoch values to readable dates for reporting queries. Log analysts decode timestamped entries in server logs. Frontend developers convert API-returned timestamps to display human-friendly times in their UI.
FAQ
- What is the difference between seconds and milliseconds? — 10-digit timestamps are seconds since epoch; 13-digit timestamps are milliseconds. JavaScript uses milliseconds; most Unix/Linux tools use seconds.
- Is Unix time affected by time zones? — No. Unix timestamps are always UTC-based. The display is converted to your local timezone, but the underlying value is absolute.
- What is the maximum Unix timestamp? — The 32-bit signed integer limit is 2,147,483,647 (January 19, 2038). Modern systems use 64-bit timestamps which extend far into the future.
