Kala has extensive calculations, as you can see below. Best of all, Kala is the only Jyotish software that calculates Planetary War, Combustion, Vara, Hora, Vyatipata, Vaidhriti and Sankranti according to the Surya Siddhanta, Varahamihira and other classical astronomy texts. Furthermore, Kala is the only Vedic Astrology software with extensive Muhurta calculations and the only software to program the entirety of mathematical techniques from Brihat Parashara Hora Shastra. Kala is thus the premier software for studying and practicing Classical Vedic Astrology.
On a more modern note: Kala has the most accurate planetary calculations, thanks to the extremely accurate Swiss Ephemeris - which is an astrologically designed version of the most accurate NASA JPL ephemeris. Kala is thus the most accurate software available to the Vedic Astrologer. Kala is able to calculate planets perfectly accurately for modern days, but also most accurately all the way from 5400 BC to 5400 AD, as compared to many other software which begin to show significant errors even when calculating only 150 years back.
