The Five days of Diwali

The Five days of Diwali
Diwali is celebrated over five days in most of North India. All the days except Diwali are named using the designation in the Indian calendar. A lunar half-month is 15 days. Diwali as a new-moon day, marks the last day of a 15-day period.

Diwali being festival of lights, across India people celebrate it via symbolic diyas or kandils (colorful paper lanterns) as an integral part of Diwali decorations.
1)Dhan-trayodashi or Dhan teras: Dhan means "wealth" and Trayodashi means "13th day". Thus, as the name implies, this day falls on the 13th day of the second half of the lunar month. It is an auspicious day for shopping.
2)Naraka Chaturdasi: Chaturdasi is the fourteenth day on which demon Narakasura was killed. It signifies the victory of good over evil and light over darkness (Gujarati: Kali Chaudas). In south India, this is the actual day of festivities. Hindus wake up way before dawn as early as 2.00 in the morning, have a fragrant oil bath and wear new clothes. They light small lamps all around the house and draw elaborate kolams /rangolis outside their homes. They perform a special puja with offerings to Lord Sri Krishna or Lord Sri Vishnu, as he liberated the world from the demon Narakasura on this day. It is believed that taking a bath before sunrise, when the stars are still visible in the sky is equivalent to taking a bath in the holy Ganges. Hence, when people greet each other in the morning, they ask "Have you performed your Ganga Snaanam?". After the puja, children burst firecrackers heralding the defeat of the demon. As this is a day of rejoicement, many will have very elaborate breakfasts and lunches and meet family and friends. In the evening, lamps are again lit and Goddess Lakshmi is worshipped and offered special dishes. This being a no moon day, many will offer special tarpana (offerings of water and sesame seeds) to their ancestors.
3)Diwali: the actual day of Diwali, is celebrated on the third day of the festival, when the moon completely wanes and total darkness sets in the night sky.
4)Govardhan Puja or also called Annakut, is celebrated as the day Krishna defeated Indra. For Annakut a mountain of food is decorated symbolizing Govardhan mountain lifted by Lord Krishna. In Maharashtra it is celebrated as Padva or BaliPratipada. The day commemorates King Bali. Men present gifts to their wives on this day.
5)Bhayiduj (also Bhayyaduj, Bhaubeej or Bhayitika) — on this day, brothers and sisters meet to express their love and affection for each other (Gujarati: Bhai Bij, Bengali: Bhai Phota). Most Indian festivals bring together families, Bhaiduj brings together married sisters and brothers, and is a significant festive day for them. This festival is ancient, and pre-dates 'Raksha Bandhan' another brother-sister festival being celebrated today.
The celebrations vary in different regions:
In Southern India, naraka chaturdashii is the main day, with firecrackers at dawn.
The main festival in North India is on Amavasya(No moon) evening with Lakshmi Puja which is followed by lighting of oil lamps around the house
