Read Our Story →Frequently Asked Questions
What is the difference between Drik Ganitha and Vakya Panchangam?
Vakya Panchangam relies on fixed archaic mnemonic verses composed centuries ago, which accumulate noticeable discrepancies over time due to axial precession and orbital perturbations. Drik Ganitha (Thirukanitham) uses modern observational ephemeris (Drik = visible / observed) ensuring that calculated planetary positions match actual telescope and satellite observations.
Which Ayanamsha does Drik Jyotish use?
By default, Drik Jyotish calculates positions using the Chitra Paksha (N.C. Lahiri) Ayanamsha, the official standard recognized by the Government of India Calendar Reform Committee. Advanced settings also support Krishnamurti Paddhati (KP) and B.V. Raman Ayanamsha.
Can I generate and download PDF Horoscope reports?
Yes. Both the web platform and mobile app allow instant generation of complete Vedic horoscope reports and 10 Porutham marriage matching reports in PDF format for printing or sharing.
