How to Use
Paste any Unix timestamp and get a complete human-readable breakdown. The unit is detected automatically, so you can paste the value straight out of logs or code.

Optionally pin the unit from the dropdown if you already know it.
Click Convert and read the result. Use Copy to grab the value you need.
What you can paste
Unix seconds such as 1750000000, and milliseconds such as 1750000000000.

Negative values, which cover dates before 1 January 1970.
Plain ISO 8601 or RFC 2822 date strings, which are parsed as well.
Features
Every precision is shown at once, so you never need a second tool.
ISO 8601 is returned in both UTC and your local offset.
