Astronomical chronology, or astronomical dating, is a technical method of dating events or artifacts that are associated with astronomical phenomena.Written records of historical events that include descriptions of astronomical phenomena have done much to clarify the chronology of the Ancient Near East; works of art which depict the configuration of the stars and planets and buildings which ...
The Hindu cosmological time cycles explained in the Surya Siddhanta, give the average length of the sidereal year (the length of the Earth's revolution around the Sun) as 365.2563627 days, which is only 1.4 seconds longer than the modern value of 365.256363004 days. [8]

By historical astronomy we include the history of astronomy; what has come to be known as archaeoastronomy; and the application of historical records to modern astrophysical problems." [1] Historical and ancient observations are used to track theoretically long term trends, such as eclipse patterns and the velocity of nebular clouds.
