About
Durga Ashtami is the eighth tithi of the bright half of Ashwina, in September or October. It is the main day of Durga Puja in Bengal and of kanya puja in North India. The tithi at sunrise is taken; when Ashtami is joined with Navami on the same day, the Ashtami puja is done in the forenoon and the texts give the Sandhi puja at the junction of the two tithis, a 48-minute window centred on the moment Ashtami ends. Some families keep Ashtami and others Navami as their household day, by lineage custom.
How it is observed
Kanya puja, the Sandhi puja at the Ashtami–Navami junction, and the chandi path in temples and pandals.
