What is Unix Timestamp Converter?

Unix Timestamp Converter converts epoch seconds or milliseconds into readable dates and back.

How to use it

Enter Unix seconds, Unix milliseconds, or a date-time value, convert in either direction, use current time or an example, and copy individual outputs.

How it works

The browser creates JavaScript Date values, auto-detects common seconds or milliseconds input, and displays UTC, local, ISO, and Unix formats.

Is data saved?

Date conversion is local and no values are stored.
