Pañcabodha is the title of several different Sanskrit treatises on astronomy and mathematics composed by members of the Kerala school of astronomy and mathematics.
All these works are karaṅa texts, that is, books which explain the various computations in astronomy especially with regard to those related to the preparation of Panchangam-s (calendar).
[1] The Pañcabodha-s generally contain five sections dealing with five topics.
However many of them treat the five advanced topics in traditional Indian astronomy, namely, Vyātīpāta (computation of the instants at which the sum of the (true) longitudes of the Sun and the Moon amounts to half a circle), Grahaṇa (computation of eclipses), Chāyā (shadow computations), Śṛṅgonnati (the computation of the elevation of the lunar horn, or the angle between the line of cusps and the horizontal plane) and Mauḍhya (computation of the instants when a planet becomes invisible due to its direction/longitude being close to that of the Sun).
Following K. V. Sarma, the various texts are identified by assigning them numbers written in Roman numerals.
