Siddhānta Śiromaṇi

What this text is

The high-water mark of classical Indian mathematical astronomy.

Līlāvatī and Bījagaṇita (mathematics), Grahagaṇita (planetary computation, including tithi, karaṇa and nakṣatra), and Golādhyāya (spherics, held with the Marīci commentary).

Its role in this app

The clearest classical exposition of how pañcāṅga limbs are computed within the tradition — used to explain, never to compute.
