Festivals associated with certain seasons.
Diwali, popularly known as the "festival of lights," is a five-day Hindu festival which starts on Dhanteras, celebrated on the 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. Dhanteras usually falls eighteen days after Dussehra. In the Gregorian calender, Diwali falls between mid-October and mid-November.
Diwali, celebrated in October or November each year, originated as a harvest festival that marked the last harvest of the year before winter. India was an agricultural society where people would seek the divine blessing of Lakshmi, the goddess of wealth, as they closed their accounting books and prayed for success at the outset of a new financial year. Today, this practice extends to businesses all over the Indian subcontinent, which mark the day after Diwali as the first day of the new financial year.
