Sankashti — sankata-hara, 'destroyer of distress' — is Ganesha's monthly day. Every lunar month has two chaturthis: the one in the bright fortnight (Vinayaka Chaturthi) and the one in the dark fortnight after the full moon, which is Sankashti. Tradition holds that Ganesha, worshipped on this tithi with a fast held until the moon is seen, removes the obstacles pressing on the devotee — debts, illness, delays, discord. Puranic tellings connect the vrata to the moon himself: Chandra, cursed for mocking Ganesha, was restored through worship on this tithi, which is why the sighting of the rising moon completes the observance rather than breaking it. Each month's Sankashti carries its own name and story in the vrata literature, and when the day falls on a Tuesday it becomes Angarika (Angaraki) Sankashti, held to be especially powerful — a coincidence devotees track eagerly. The Sankashti falling in the month of Pausha/Margashirsha–Pausha season is honoured in Tamil tradition within the larger reverence for Sankatahara Chaturthi year-round.

The observer rises early, bathes, and takes the sankalpa to fast until moonrise — a full fast for the strict, fruits and milk for most. The day passes in ordinary work with the fast held quietly. At dusk the pooja is performed: Ganesha is worshipped with the twenty-one blades of durva grass he loves, red flowers, and naivedyam of modaka or kozhukattai/kudumulu — the steamed sweet dumpling that is his signature across all four southern states under different names. The Sankashtanashana Ganapati Stotram from the Narada Purana tradition is the vrata's classic recitation; the Ganapati Atharvashirsha and simple namavalis are equally loved. Then comes the wait for the moon. When it rises, arghya — water, often with sandal and flowers — is offered to Chandra, a final prayer to Ganesha is made, and only then is the fast broken with the prasadam. Ganesha temples across the South, from Karnataka's idagunji and Anegudde to Tamil Nadu's Pillaiyar shrines, see their biggest monthly crowds on this evening.

Sankashti is one of the most Canada-friendly vratas: it needs only a home altar, a Ganesha murti or image, and the moon. The one practical point is moonrise time, which in Ottawa swings widely — a Sankashti moon can rise anywhere from about 8 pm to close to midnight depending on the season, since the fast-breaking moon is a waning gibbous that rises well after sunset. Check the site's panchang for Ottawa moonrise on the day, and note that the correct vrata date is the one on which the chaturthi tithi prevails at Ottawa moonrise — occasionally a day different from India's. Winter observers get an early moonrise and a cold, clear sky; summer observers should plan a late dinner. Modakas steam perfectly well in a Canadian kitchen with rice flour, coconut and jaggery from any Indian grocery. On overcast nights, tradition allows offering arghya at the calculated moonrise time when the moon cannot be seen.
