How It Works
The Unix timestamp (also known as Epoch time) is the number of seconds that have elapsed since January 1, 1970 (midnight UTC/GMT). This tool converts between timestamps and human-readable dates entirely in your browser.
- Timestamp to Date: Enter a Unix timestamp and select the correct format (seconds or milliseconds). The tool displays the equivalent date in both UTC and your local timezone.
- Date to Timestamp: Pick a date and time using the date picker and instantly see the corresponding Unix timestamp in seconds and milliseconds.
- Current Timestamp: The live display shows the current Unix timestamp (seconds) updating every second.
