Diwali, festival of lights, is an ancient Hindu festival that takes place each year between mid-October and mid-November. Deepawali or Diwali is the largest, and the brightest of all Hindu festivals officially celebrated in Fiji, Guyana, India, Malaysia, Mauritius, Nepal, Singapore, Sri Lanka, Suriname and Trinidad and Tobago. The festival is marked for five days of celebration, whereas each day is distinguished by a different tradition.
Before the Diwali night people clean, renovate and decorate their houses with diyas, lamps and candles and create design patterns called rangoli on the floor using colored powders or sand. On the third night of Diwali, families gather in Lakshmi Puja, a traditional family prays to Lakshmi, a Hindu goddess of wealth and prosperity. The Lakshmi Puja is followed by mouth-watering feasts and fireworks.
The fourth day of Diwali, Padva is dedicated to wife–husband relationship, while Bhau-Beej, the last day festival is dedicated to sister–brother bond when brothers visit their married sisters who welcome them with love and a lavish meal.
