KNOW ABOUT DIWALI

Divali which is also known as Deepavali.This is a significant festival of Hindus and an official holiday in India.the meaning of it is "Row of Lights". Adherents of these religions celebrate Diwali as the Festival of Lights. They light diyas—cotton-like string wicks inserted in small clay pots filled with coconut oil—to signify victory of good over the evil within an individual.
Diwali celebrates in the memory of the return of Rama,who was King of Ayodhya, with his wife Sita and brother Lakshmana to Ayodhya after a 14 year exile, and a war in which he killed Ravana. It is believed that the people of Ayodhya lit ghee lamps along the way to light their path in the darkness.
The five day festival of Divali occurs on the new moon between October 13 and November 14. On the Hindu calender it is centered on the new moon day that ends the month of Ashwin and begins the month of Kartika, beginning on the 13th day of the dark half of Ashwin (Ashwin 28th) and ending on the 2nd day of the bright half of Kartika (Kartika 2nd). The main day of celebration varies regionally.
In Hinduism, across many parts of India and Nepal, it is the homecoming of Rama after a 14-year exile in the forest and his victory over the Ravana. In the legend, the people of Ayodhya (the capital of his kingdom) welcomed Rama by lighting rows (avali) of lamps (dĭpa), thus its name: dipawali. Over time, this word transformed into Divali in Hindi and Dipawali in Nepali, but still retained its original form in South and East Indian Languages.
