What is Dussehra?
Dussehra — Vijayadashami — marks Rama’s victory over Ravana and Durga’s over Mahishasura, on the tenth day of the waxing moon in Ashwin. Its date is set by the *aparahna*, the afternoon window, since that is when the victory is commemorated.
How it is observed
Effigies of Ravana are burnt at dusk across north India, closing a fortnight of Ramlila performances. The day is considered auspicious for any beginning, needing no separate muhurat.
