A Vakya Panchangam is a traditional South Indian almanac based on ancient "sentences" or aphorisms attributed to sage Agastya. Unlike the modern Drig-Ganita (mathematical) method, Vakya calculations are rooted in hereditary tradition, often used by temples like Srirangam for festival dates. 🛠️ Step 1: Gather Accurate Data

Unlike the Thirukanitha system, which uses trigonometry and modern astronomy to calculate the exact angular position of planets, Vakya Panchangam uses the traditional mathematical shortcuts provided in ancient texts like the Surya Siddhanta.

Most Indian astrologers use the Drik Panchangam (based on "Drik" or actual visibility) or Tirukkanitha Panchangam. The Vakya Panchangam, however, is based on ancient mathematical formulas derived from the Surya Siddhanta and the works of sage Maya and Vateswara.
