Mahanawami festival or the ninth day of 10-day Bada Dashain festival is being observed on Thursday by worshiping goddess Durga Bhawani and making offerings. 

This festival is observed on the ninth day of the waxing moon in the month of Asoj as per the lunar calendar. The day is dedicated to goddess Siddhidatri—one of the forms of goddess Durga. People worship their vehicles and motorbikes on this day. 

Special worship is performed to Durga Bhawani today on the occasion of the Mahanawami and the 'jamara' which have been germinated is offered to the goddesses at various shrines. 

He-goats, ducks, roosters, and he-buffalos are sacrificed at various temples dedicated to the goddesses. Those who do not have the tradition of offering animal or bird sacrifices offer the sacrifice of fruits and vegetables to the goddess. 

The Durga Saptasati and Devi Strota scriptures are also recited at home and in temples on this day. 

As mentioned in the Markandeya Purana scripture, the Goddess Chamunda had slain the demon Raktabij on the day of Mahanawami. So, the special worship of the goddess is conducted this day with the offering of animal sacrifices. 

The Taleju Temple located at Hanumandhoka in the capital city is also opened for the devotees to pay homage on this day. It is opened only on the occasion of the Mahanawami. 

The people of the Newar community also worship Bhimsen, a Hindu deity, by making animal sacrifices today on the occasion of Mahanawami.
