Timestamp Converter
Convert dates to Unix timestamp and vice versa.
What is a Unix Timestamp?
A Unix timestamp is a system for describing a point in time. It is defined as the number of seconds that have elapsed since 00:00:00 UTC on January 1, 1970, a moment known as the 'Unix Epoch'. It is the de facto standard for working with dates in programming due to its simplicity and universality.
Why use a converter?
While computers work efficiently with timestamps, for humans they are just long, unreadable numbers. This tool serves as a bridge, allowing you to convert a date you understand (like 'October 25, 2025') to its numerical equivalent, and vice versa. It is an indispensable utility for developers, data analysts, and anyone working with APIs or databases.
Our calculator handles timestamps in both seconds (the standard, 10 digits) and milliseconds (13 digits), automatically detecting the format you enter.
