Observing Sankashti Chaturthi Fast and Rituals
Written and reviewed by The Kriya Yogi · Updated 25 September 2026
Sankashti Chaturthi, also known as Sankata Hara Chaturthi, is an auspicious day dedicated to Lord Ganesha that falls on the fourth day (Chaturthi) of the waning phase of the moon (Krishna Paksha) every month.
The short answers
- Purpose: The word 'Sankashti' means deliverance during troubled times.
- The Fast: Devotees observe a partial or full fast from sunrise until the sighting of the moon.
- Moon Sighting: The fast is broken only after seeing the moon and offering prayers to Ganesha and the Moon God (Chandra).
- Angarki Chaturthi: When Sankashti falls on a Tuesday, it is considered exceptionally auspicious and called Angarki Chaturthi.
Observing this fast is a way for devotees to seek Ganesha's help in removing hurdles from their path. During the day, practitioners read the 'Sankashtnashana Stotram' and meditate on the different forms of Ganesha assigned to each month. The ritual typically involves a special puja performed in the evening. While many believe this practice brings relief from difficulties, it is a spiritual discipline intended for inner growth and devotion rather than a guaranteed solution to external problems.
Approaching it with care
Morning Sankalpa
Wake up early, take a bath, and make a firm resolve (sankalpa) to observe the fast.
Daytime Devotion
Maintain a light diet (fruits/milk) and chant Ganesha mantras throughout the day.
Evening Puja and Arghya
After moonrise, perform a puja and offer 'Arghya' (water offering) to the moon and Ganesha.
Cautions worth reading
- Pregnant women, children, and those with medical conditions should consult a doctor before fasting.
