Time and date are essential in spherical astronomy, as they are used to calculate the positions of celestial objects. However, the Earth's rotation and orbit are not perfectly uniform, causing small variations in time and date.

Measures an object’s position relative to the observer's local horizon using Altitude (height above the horizon) and Azimuth (angle from the North).
