Frequently Asked Questions

Everything you need to know about Unix timestamps and date conversion.

What is a Unix timestamp?

A Unix timestamp is the number of seconds (or milliseconds) that have elapsed since January 1, 1970 00:00:00 UTC, also known as the Unix Epoch. It is widely used in programming, databases, and APIs to represent points in time.

How do I convert a Unix timestamp to a date?

Paste your Unix timestamp into the input field above. The converter instantly displays the equivalent date and time in multiple formats including local time, UTC, and ISO 8601.

What is the difference between seconds and milliseconds timestamps?

Unix timestamps in seconds are 10 digits long (e.g. 1700000000). Millisecond timestamps are 13 digits long (e.g. 1700000000000). The converter automatically detects which format you are using.

What is the maximum Unix timestamp value?

The maximum 32-bit Unix timestamp is 2147483647, which corresponds to January 19, 2038. This is known as the Year 2038 problem for systems using 32-bit integers.

Is my data sent to a server?

No. All conversion happens locally in your browser using JavaScript. Your timestamp data never leaves your device.
