About Time Units
Time is a fundamental dimension of the universe that allows us to sequence events, measure durations, and quantify change. As one of the seven SI base quantities, time underpins everything from daily scheduling to cutting-edge scientific research. The second (s) is the SI base unit of time, defined by the precise oscillation of cesium atoms.
Second
The second originated from astronomical observations and is now defined by the vibration of cesium atoms. It forms the foundation for all modern timekeeping systems.
Minute
Minutes have roots in Babylonian astronomy, where base-60 calculations dominated. They bridge the gap between precise seconds and longer human-scale intervals.
Hour
Hours were historically linked to the apparent movement of the Sun across the sky. Today they remain the most common unit for scheduling work, travel, and broadcasts.
