Diwali, Devali or Deepavali is popularly known as the "festival of lights,". Diwali is an official holiday in India, Nepal, Sri Lanka, Myanmar, Mauritius, Guyana, Trinidad & Tobago, Suriname, Malaysia, Singapore and Fiji. For Hindus, Diwali is one of the most important festivals of the year and is celebrated in families by performing traditional activities together in their homes. For Jains, Diwali marks the attainment of moksha or nirvana by Mahavira in 527 BCE.
Diwali is a five day festival which starts on Dhanteras, celebrated on thirteenth lunar day of Krishna paksha (dark fortnight) of the Hindu calendar month Ashwin and ends on Bhaubeej, celebrated on second lunar day of Shukla paksha (bright fortnight) of the Hindu calendar month Kartik. In the Gregorian calendar, Diwali falls between mid-October and mid-November.
Diwali marks the end of the harvest season in most of India. Farmers give thanks for the bounty of the year gone by, and pray for a good harvest for the year to come. Traditionally this marked the closing of accounts for businesses dependent on the agrarian cycle, and is the last major celebration before winter. Lakshmi symbolizes wealth and prosperity, and her blessings are invoked for a good year ahead.
