The Surya Siddhanta text has survived since the ancient times, has been the best known and the most referred astronomical text in the Indian tradition. [7] The fourteen chapters of the Surya Siddhanta are as follows, per the much cited Burgess translation: [4] [43] Of the Mean Motions of the Planets [3] On the True Places of the Planets [3]: 53
Later writer Yallaya (c. 1480), in his commentary on the Surya Siddhanta, praises Suryadeva as an "all-knowing astronomer". [4] In his commentary on the Laghumanasa, he states the planetary positions for a particular day in 1248 CE (Shaka year 1170), which suggests that he wrote the commentary at the age of 57, in 1248.

Greek astronomical texts were translated from Jyotisha Shastra Sanskrit pertaining of Surya Siddhanta and other works by different Indian Scholars. Similar to how most books of philosophy, mathematics in Sanskrit Literature made its way into Greece by trade.
The Surya Siddhantha concisely specifies the coordinates of the twenty-seven Nakshatras. [7]: 211 It is noted above that with the older tradition of 28 Nakshatras each equal segment would subtend 12.85 degrees or 12° 51′. But the 28 Nakshatra were chosen at a time when the Vedic month was recognised as having exactly 30 days.
Makarandasāriṇi follows the Saurapakṣa.This is the midnight-epoch system embodied in a recension of the Sūryasiddhānta dating to around the eighth century. [1] This is reflected in the choices of the values of the fundamental parameters, like the values of the celestial bodies’ revolution-numbers and consequent mean velocities.
The Surya Siddhanta (1.10–21) describes units of time from a respiration (prana) [50] up to the 100-year lifespan of Brahma (maha-kalpa). [ 51 ] lokānām antakṛt kālaḥ kālo 'nyaḥ kalanātmakaḥ ।
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. [10]
Similarly, the Paitamaha Siddhanta referred to by Varāhamihira was probably composed in the early 5th century (distinct from an even earlier work of the same name [11]), but the present-day text is a later work that survives as part of a Purana text. [12] Thus, Varāhamihira's text is the only source about these ancient treatises. [13]
