How is the Amavasya date calculated?
Amavasya is the 30th tithi, the last of Krishna paksha: the Moon 348°–360° ahead of the Sun, ending at the exact new moon. The table gives the tithi's start and end and the day it is current at sunrise. Amavasya at sunrise on a Monday is Somvati Amavasya, on a Saturday Shani Amavasya.
Sun and Moon positions: Swiss Ephemeris with its data files, sidereal, Lahiri (Chitrapaksha) ayanamsa. Sunrise: upper limb of the Sun with standard refraction at the city centre. A tithi's start and end are the same instant everywhere; only the clock time and the sunrise day change with the city. Methodology
