Sankashti Chaturthi

Vidhi. Monthly Krishna Chaturthi for Ganesha. Fast from sunrise; many keep fruit and water. The fast is broken after moonrise, not at a fixed wall-clock hour.

Paran. Sight the moon in your city, then offer and eat. Open that evening's panchang for moonrise — Jaisalmer and Kolkata differ.

Mantra. Om Gan Ganapataye Namah

Angaraki (Tuesday) Sankashti is treated as especially fruitful. Civil dates can shift by a day at city sunrise; use the day page if your family is strict.
