About Sunrise & Sunset Calculation
Sunrise and sunset times are calculated using the Drik (Thirukanitha) method with the Swiss Ephemeris and Lahiri Ayanamsha. The calculation accounts for the geographic coordinates and timezone of the selected location, giving precise local times for each day.
Sunrise is the foundational input for all Panchanga calculations. Every daily timing — Rahu Kalam, Yamagandam, Gulika Kalam, Nalla Neram, Hora — is derived by dividing the day (sunrise to sunset) into equal parts.
