Frequently Asked Questions

What is a Unix Timestamp?

It is a system for describing a point in time. It is the number of seconds that have elapsed since the Unix Epoch (January 1, 1970, at 00:00:00 UTC).

Why is my converted year 50,000?

You likely pasted a 13-digit JavaScript timestamp (milliseconds) into a tool expecting a 10-digit Unix timestamp (seconds). Use our Seconds/Milliseconds toggle.

Does it account for leap years?

Yes, the underlying math handles leap years and leap seconds precisely.

What happens in the year 2038?

The "Year 2038 problem" occurs because 32-bit systems will run out of space to count the seconds. Modern 64-bit systems, which this tool uses, have solved this issue.

Does it support milliseconds?

Yes, it intelligently detects whether the timestamp is in seconds or milliseconds.

Does it show my local timezone?

Yes, it outputs both UTC (GMT) and your computer's local timezone automatically.

Can I convert a date back to a timestamp?

Yes, it works in both directions.

Is this a free timestamp converter?

Yes, this free timestamp converter is a developer favorite.

Why use the best epoch tool?

Because it prevents developers from doing complicated mental math with seconds.
