  2. Enter or paste your Unix timestamp (in seconds or milliseconds)
  3. View the converted date in both UTC and your local timezone
  4. The tool automatically detects and handles Daylight Saving Time (DST)

Converting Date to Unix Timestamp

  1. Select "Date" input mode
  2. Choose whether your date is in Local Timezone or UTC
  3. Either use the date picker or paste a date string (the tool intelligently parses various formats)
  4. View the converted Unix timestamp in seconds and milliseconds

What is Unix Timestamp (Epoch Time)?

Unix timestamp (also known as Epoch time or POSIX time) is a system for describing points in time. It is the number of seconds that have elapsed since 00:00:00 UTC on 1 January 1970 (the Unix epoch), not counting leap seconds. This date and time is sometimes referred to as the "Unix epoch."

Unix timestamps are widely used in programming and computer systems because they provide a simple, unambiguous way to represent dates and times that works across different timezones and locales.

Common Use Cases

  • Debugging timestamp values in logs and databases
  • Converting API response timestamps to readable dates
  • Testing date/time functionality in applications
  • Analyzing server logs with Unix timestamps
  • Converting dates for database queries
  • Working with JavaScript Date objects (which use milliseconds)

Privacy & Security

All conversions are performed locally in your browser. No data is sent to any server, ensuring your timestamps and dates remain completely private.
