The Navaratri we celebrate right now is sharad Navratri. It commences on the first day (pratipada) of the bright fortnight of the lunar month of Ashwin. The festival is celebrated for nine nights once every year during the beginning of October, although as the dates of the festival are determined according to the lunar calendar, the festival may be held for a day more or a day less.
Navaratri is celebrated in different ways throughout India. In North India, all three Navratris are celebrated with much fervor by fasting on all nine days and worshipping the Goddess Parvati in her different forms. The Chaitra Navratri culmintes in Ram Navami and the Sharad Navratri culminates in Durga Puja and Dussehra. The Dussehra of Kulu in Himachal Pradesh is particularly famous in the North.
In the South Indian states of Tamil Nadu & Karnataka, Sharad Navratri is celebrated by setting up of Golu (pronounced as Golu or Kolu) or Bombegalu. It is believed[who?] that this was a means to invite people home to celebrate the festivities with them. In Karanataka, particularly Mysore on the 10th day the enacting of destruction of evil (Ravana destroyed by Rama) is displayed with the lighting of dolls representing Ravana and forces of evil (2.5 millennia earlier version of the British Guy Faukes Day - Nov 5th).
