⏱️ Unix Time Converter
Convert a Unix timestamp into a readable UTC date and time.
What this calculator does
This tool converts a Unix timestamp, the number of seconds (or milliseconds) elapsed since midnight UTC on January 1, 1970 (the ‘Unix epoch’), into a human-readable UTC calendar date and time.
How the calculation works
The calculator takes your timestamp, converts it to milliseconds if needed, and builds a standard date object from it, then reads out the UTC year, month, day, hour, minute, second, and day of the week.
Unix time is widely used in computing, databases, and APIs because it represents any moment as a single, unambiguous number regardless of time zone. This tool is intended for general programming and educational reference.
