Your question is not clear. Do you ask why do we celebrate Diwali or how do we celebrate Diwali? However, I will answer both the questions in brief: 1. Diwali or Deepawali (Line of Lamps) is the major festival of North India. It is held to commemorate the return of a very loved prince Rama (who is considered to be the seventh incarnation of Supreme God of a section of hindus, the Vaishnavas, worshipers of Lord Vishnu). Though the celebration is not restricted to just the Vaishnavas and all hindus celebrate it. Rama returned after a 14 year banishment to fulfill a vow given by his father to one of his queens. Immediately before the return, Rama had fought a war with the most evil king of his time, Ravana, and killed him. The victory of Rama over Ravana is celebrated as another major festival, known as Vijaya Dashami (the victory of the tenth of the fortnight). Rama later ruled his kingdom for many years and is remembered as a king in whose reign, none of his subjects were unhappy. 2. As I mentioned, we celebrate Vijaya Dashami a few days before Diwali. At that time three paper statues of Ravana, his brother, and his son, are made and stocked with fire-works. In the evening these statues are lighted before the populace. This symbolises victory of good over evil. The story of Rama is played out in every locality for 14 days. People get their houses renovated or painted before Diwali, useless junk is thrown away, so that every thing should be spotlessly on Diwali. Diwali is a great time for business (just like Christmas in West. People make their valuable purchases during Diwali. Two days before Diwali there is a subsidiary festival when all people are supposed to buy something from the market (if not jewels and ornaments, then at least a few things for use in the kitchen). The night before Diwali, gambling is considered auspicious. On Diwali day, merchants do not conduct any business, however the shops are kept open. After an evening worship at the shop and work-places, people come to home, conduct their own worship. Then the fire-works are lighted by all households. It is a noisy evening and the celebrations continue till mid-night. People may eat at home or go to acquaintances and relatives to wish them. The day next to Diwali is known as Govardhan (increase in live-stock) and in villages the live-stock is worshiped. Though in cities, there is no live-stock, still the occasion is celebrated by lighting lamps. The second day after Diwali is considered auspicious for brothers and sisters. If the sister is married, the brother will go to her house and bring her to the father's home where she is dined and given gifts. The sister in turn will tie a thread on the brother's wrist, signifying that the brother will safe-guard the sister all the time. With that finish the Diwali celebrations.

Sikhs do not celebrate Diwali they celebrate bani chhor diwas. The word "Bandi" is translated from Punjabi into English as "Imprisoned" (or "Prisoner"), "Chhor" as "Release," and "Divas" as "Day," rendering "Bandi Chhor Divas" from Punjabi into English as "Prisoners' Release Day." Bandi Chhor Divas coincides with the Hindu festival of Diwali ("The Festival of Lights"), which has resulted in a similarity of celebrations among Sikhs and Hindus on their respective holy days and has led to confusion between the two holidays and the mistaken belief that the holidays are one and the same, which they are not. Bandi Chhor Divas is a celebration of the safe return of Guru Har Gobind and his followers from detention at the Gwalior Fort (Gwalior, Madhya Pradesh, India) in the Fall of 1619.
