How to use the Unix timestamp converter

  1. Enter timestamp or date

    Enter a Unix timestamp number, or a date in any common format.

  2. Convert

    Click 'Convert' to see the equivalent date or timestamp.

  3. Review the result

    See the converted date in UTC and your local timezone.

  4. Check current timestamp

    See the current Unix time updating in real time if you need the current timestamp.

  5. Copy the result

    Copy the timestamp or formatted date for use in your code or documentation.

What is a Unix timestamp converter?

The Unix Timestamp Converter converts between Unix timestamps (seconds since January 1, 1970 UTC) and human-readable date/time formats. Enter a timestamp to get the date, or enter a date to get the Unix timestamp — supporting both seconds and milliseconds epoch formats.

Unix timestamps are the universal standard for storing and transmitting dates in programming. They're used in APIs, databases, log files, and server responses. Converting between epoch time and readable dates is a constant need in software development.

Why use a Unix timestamp converter?

API responses return epoch timestamps; humans read dates. Database queries use Unix time; debugging requires readable dates. This converter bridges the gap instantly — converting any timestamp to a readable date or any date back to the timestamp your code needs.

What is a Unix timestamp?

A Unix timestamp is the number of seconds that have elapsed since 00:00:00 UTC on January 1, 1970 (the Unix epoch). It's a single integer that uniquely identifies any point in time, universally used in computing.

What is the Unix epoch?

The Unix epoch is January 1, 1970, 00:00:00 UTC — the reference point from which Unix timestamps are counted. Every second after this date is one higher timestamp.

What is the difference between second and millisecond timestamps?

Most Unix timestamps are in seconds. JavaScript (Date.now()) returns milliseconds. A second timestamp has 10 digits (1700000000); a millisecond timestamp has 13 digits (1700000000000). Always check which your system uses.

Will Unix timestamps work past 2038?

32-bit systems store Unix timestamps as signed 32-bit integers, which overflow in January 2038 (the 'Year 2038 problem'). Modern 64-bit systems use 64-bit timestamps that won't overflow for billions of years.

Can I convert dates in different timezones?

The converter shows both UTC and your browser's local timezone. For specific timezone conversion, note the UTC timestamp and apply your required UTC offset.
