How the planner chooses dates
A muhurat is a time chosen to give a new beginning the best start. We judge each day at its midday (Abhijit) muhurat for the tithi, the Moon's nakshatra and the weekday, using the traditional lists of favourable stars for each activity. Rikta tithis (4th, 9th, 14th) and Amavasya are always skipped.
For marriage and griha pravesh we are stricter: we also skip Kharmas (when the Sun is in Dhanu or Meena) and the days when Venus or Jupiter is combust, as tradition advises.
What it does not do
This is a simplified planner. It does not model Chaturmas, adhik maas or eclipses, and it does not match the date to anyone's personal chart. Please confirm the final date and time with a local pandit, especially for weddings and housewarmings.
