Deepavali is an official holiday in India, Nepal, Sri Lanka, Myanmar, Mauritius, Guyana, Trinidad & Tobago, Suriname, Malaysia, Singapore,and Fiji.
The name "Diwali" is a contraction of "Deepavali" (Sanskrit: दीपावली Dīpāvalī), which translates into "row of lamps". Diwali involves the lighting of small clay lamps (diyas or dīpas) in Sanskrit: दीप) filled with oil to signify the triumph of good over evil. During Diwali, celebrants wear new clothes and share sweets and snacks with family members and friends.
The festival starts with Dhanteras on which most Indian business communities begin their financial year.
The second day of the festival, Naraka Chaturdasi, marks the vanquishing of the demon Naraka by Lord Krishna and his wife Satyabhama.
Amavasya, the third day of Deepawali, marks the worship of Lakshmi, the goddess of wealth in her most benevolent mood, fulfilling the wishes of her devotees. Amavasya also tells the story of Lord Vishnu, who in his dwarf incarnation vanquished the Bali, and banished him to Patala.
It is on the fourth day of Deepawali, Kartika Shudda Padyami, that Bali went to patala and took the reins of his new kingdom in there.
The fifth day is referred to as Yama Dvitiya (also called Bhai Dooj), and on this day sisters invite their brothers to their homes.

Deepavali is a festival where people from all age oups participate.
They give expression to their happiness by lighting earthen 'diyas' (lamps), decorating the houses, bursting firecrackers and inviting near and dear ones to their households for partaking in a sumptuous feast. The lighting of lamps is a way of paying obeisance to god for attainment of health, wealth, knowledge, peace, valor and fame.
It is one time in the whole year that children volunteer to leave their beds long before the day begins. In fact, the traditional oil bath at 3 a.m, is the only chore that stands between them and the pre-dawn adventures. They emerge, scrubbed clean to get into their festive attire, and light up little oil lamps, candles and scented sticks(agarbathis), the wherewithal for setting alight crackers and sparklers.
On Diwali night, little clay lamps are lit in Hindus homes, but now a days colored electric lamps are also used. What is the significance of lighting a lamp? There is a logical answer to this question. It is through the light that the beauty of this world is revealed or experienced.

After a session of bursting crackers, its time to visit friends and relatives. Armed with sweets and savories people meet their near and dear ones.
