📐 HOW MASTRO CALCULATES
IN PLAIN WORDS (ELI5)
We perform exact celestial mathematics using Swiss astronomy algorithms, freeze the planetary coordinates down to the second of arc, and only then derive classical Parashara interpretations. Every word in MASTRO is anchored in verifiable math.
True Lahiri Ayanamsha (Chitrapaksha)
Accounts for the Earth's axial precession (~50.29 arcseconds/year). We measure angular difference from fixed star Spica (Chitra at 180°00′00″):
Lagna Spherical Trigonometry
Ascendant is the exact degree rising over the eastern horizon at geographical latitude (φ) and longitude (L) using Local Sidereal Time (θ):
BPHS Ashtakoota 36-Guna Algorithm
Strict Brihat Parashara Hora Shastra rules analyzing all 8 Kootas: Nadi (8), Bhakoot (7), Gana (6), Maitri (5), Yoni (4), Tara (3), Vashya (2), Varna (1).
BaZi Solar Term Year Transition
Four Pillars calculates solar longitude passing 315° (Li Chun / Start of Spring) rather than the lunar calendar, guaranteeing true Day Master accuracy.
Why We Charge Strictly ₹1 Per Nakshatra (₹27)
Traditional commercial portals terrify users with fake "Kaal Sarp" or "Mangal Dosha" curses to sell ₹2,999 gemstone rings. MASTRO was built to offer raw, uncorrupted ephemeris science so every Indian seeker has access to the mathematical truth.
