Diwali

Diwali, also called Deepavali, is a major Indian festival that is very significant in Hinduism, Sikhism and Jainism. Known as the "Festival of Lights," it symbolises the victory of good over evil, and lamps are lit as a sign of celebration and hope for humankind. Celebrations focus on lights and lamps, particularly traditional dīpa or deeya (earthen lamp, as illustrated). Fireworks are associated with the festival. Diwali is a colloquial name used in North India, while the festival is formally called Deepavali in South India.
	Diwali is celebrated for three consecutive days at the end of Hindu month of Ashwayuja. It usually occurs in October/November, and is one of the most popular and eagerly awaited festivals in India. Diwali comes exactly twenty days after Dussehra. Hindus and Sikhs alike regard it as a celebration of life and use the occasion to strengthen family and social relationships. For Hindus it is one of the most important festivals, and beginning of the year in some Hindu calendars. There are several beliefs regarding the origin of the holiday. The most repeated version is that Hindus celebrate Diwali to mark the time when Lord Rama achieved victory over Ravana. Some also view it as the day Krishna defeated the demon Narakasura or in honor of the day Bali went to rule the nether-world, obeying the order of Vishnu. It is also a significant festival for the Sikh faith. In India, Diwali is now considered to be more of a national festival, and the aesthetic aspect of the festival is enjoyed by most Indians regardless of faith.
Dates in various calendars: The festival is celebrated for a differing number of days by different communities. In Maharashtra and Karnataka, the celebrations start from Vasubaras, 12th day of the second fortnight of Ashvin (going on for 6 days) while in Northern India the celebrations start from Laxmi Puja the no moon day of the same month (going on for 2-3 days). Though the core days are common and fall on exactly the same set of days across India, they fall in different months depending on the version of the Hindu calendar being used in the given region. The Amanta ("ending on the no-moon") version of the Hindu Calendar has been adopted as the Indian national calendar. According to this calendar, which is prevalent in southern India and Maharashtra, the 6-day celebration is spread over the last four days of the month of Ashwayuja and the first two days of the new month of Kartika. According to the Purnimanta ("ending on the full-moon") version prevalent in northern India, it falls in the middle of the month of Ashwayuja/Ashvin. In the Gregorian calendar, it falls generally in the months of October or November. In 2006, it was celebrated on October 21 (Saturday).
Significance in Hinduism: The festival marks the victory of good over evil. The Sanskrit word Deepavali means an array of lights that stands for victory of brightness over darkness. As the knowledge of Sanskrit diminished, the name was popularly modified to Diwali, especially in northern India. In South India, Diwali does not coincide with the beginning of a new year as South Indians follow a different calendar, the Shalivahana calendar. On the day of Diwali, many wear new clothes, share sweets and snacks, and light firecrackers. Some North Indian business communities start their financial year on Diwali and new account books are opened on this day. Hindus find cause to celebrate this festival for different reasons: It commemorates the killing of Narakasura, an evil demon who created havoc, by Lord Krishna's wife Satyabhama. This happened in the Dwapara Yuga during this time of Lord Krishna's avatar. In another version, the demon was killed by Lord Krishna himself. Before Narakasura's death, he requested a boon from his mother, Satyabhama (believed to be an Avatar of Bhudevi - Narakasura' mother), that everyone should celebrate his death with colorful light.
According to the Skanda Purana, the goddess Shakti observed 21 days of austerity starting from ashtami of shukla paksha (eighth day of the waxing period of moon) to get half of the body of Lord Shiva. This vrata (austerity) is known as kedhara vrata. Deepavali is the completion day of this austerity. This is the day Lord Shiva accepted Shakti into the left half of the form and appeared as Ardhanarishvara. The ardent devotees observe this 21 days vrata by making a kalasha with 21 threads on it and 21 types of offerings for 35 days. The final day is celebrated as kedhara gauri vrata. Read More.....
