Unix Timestamp Converter - Epoch to Date
Instantly convert Unix timestamps (epoch time) to readable human dates, and vice versa. This free developer tool calculates timezone differences and date strings locally in your browser.
What is a Unix Timestamp Converter?
A Unix timestamp (or Epoch time) is a system for describing a point in time, specifically the number of seconds that have elapsed since January 1, 1970 (UTC). Developers and databases use it because it is an absolute integer that avoids timezone confusion. However, it's unreadable to humans. This converter acts as a bridge, allowing you to instantly translate a Unix integer into a standard date string, or take a specific date and generate its Unix equivalent. All time math is performed using your browser's local JavaScript engine.
