c7.s7.22

A large number of astronomical manuals based on the *Parahita* system, including a *Grahacāranibandhana-saṅgraha*,² have come to be composed during later times, both in Sanskrit and in Malayalam, each taking off from a convenient contemporary epoch (*khaṇḍa-dina*) for which the True positions of the planets would have been fixed after elaborate calculations, these positions being used as zero-corrections for computation according to these manuals. Some of these incorporate also further corrections.
