How these timings are calculated
BDA calculates the geocentric angular separation of the Moon and Sun and divides the full cycle into 30 equal 12-degree Tithi sectors. UTC boundaries are converted to the timezone resolved from the listed city coordinates.
Scope: These are astronomical Tithi spans only. This page does not choose a festival, Vrat, Parana, or Muhurta date. Those decisions require their separately certified sunrise-prevalence and observance rules.
