Aparajita Puja is observed on Vijayadashami (Dussehra) during Navratri Durga Puja. In 2016, Aparajita Puja date is October 11. ‘Aparajita’ means the one who is unbeatable.
It falls on Dashami in Shukla Paksha Ashwin Month. Aparajitha Devi is not a manifestation of Goddess Durga but a form which symbolizes the victory of the Goddess over demons.
Vijay Muhurat on Vijaya Dashami is an auspicious time for Aparajitha Puja. Those who perform this puja would not have defeats and will get confidence and courage to face any sort of tough situations in life.
After performing Aparajitha Puja, Durga Visarjan is done on Dashami day.
