How do I convert a Unix timestamp to a human-readable date?

Enter your Unix timestamp in seconds or milliseconds into the converter. The tool will automatically detect the format and display the corresponding date and time in multiple timezones and formats. You can copy the result in your preferred format.

What is the difference between seconds and milliseconds timestamps?

Unix timestamps in seconds are 10 digits long (e.g., 1703980800), while milliseconds timestamps are 13 digits long (e.g., 1703980800000). JavaScript and many APIs use milliseconds, while traditional Unix systems use seconds. Our converter handles both formats automatically.

Why do developers use Unix timestamps?

Unix timestamps are timezone-independent, making them ideal for storing and comparing dates across different systems. They are simple integers that can be easily stored, sorted, and calculated. Most programming languages and databases have built-in support for Unix timestamps.

How do I get the current Unix timestamp?

Our converter displays the current Unix timestamp in real-time at the top of the tool. You can also get it programmatically: in JavaScript use Date.now() for milliseconds or Math.floor(Date.now()/1000) for seconds; in Python use time.time(); in Bash use the date +%s command.

What is the Unix epoch and why is it January 1, 1970?

The Unix epoch is the starting point for Unix time: January 1, 1970, at 00:00:00 UTC. This date was chosen by the creators of Unix as a convenient, round number that was recent enough to be useful but far enough in the past to cover most computing needs at the time.

Can I convert dates from different timezones?

Yes! Our Unix timestamp converter displays the converted time in 14 different timezones simultaneously, including UTC, major US timezones, European timezones, and Asian timezones. You can easily see what time it is in any of these zones.

What is the Year 2038 problem with Unix timestamps?

The Year 2038 problem affects 32-bit systems that store Unix timestamps as signed 32-bit integers. On January 19, 2038, at 03:14:07 UTC, the timestamp will overflow and wrap around to negative numbers. Modern 64-bit systems use 64-bit timestamps, which can represent dates billions of years into the future.

Frequently Asked Questions

A Unix timestamp (also known as epoch time or POSIX time) is a way of tracking time as a running total of seconds. It represents the number of seconds that have elapsed since January 1, 1970, at 00:00:00 UTC, not counting leap seconds. This date is known as the Unix epoch.
