What are Hour and Sidereal

Definition of Hour

An hour is a unit of time conventionally reckoned as 1⁄24 of a day and scientifically reckoned as 3,599–3,601 seconds, depending on conditions. The seasonal, temporal, or unequal hour was established in the ancient Near East as 1⁄12 of the night or daytime.

Definition of Sidereal

Sidereal time is a timekeeping system that astronomers use to track the direction to observe stars across the night sky. It is based on Earth's rate of rotation measured relative to the fixed stars rather than the Sun.
