Diwali celebrations traditionally last for five days. The festival typically includes the observances of several significant days such as Dhanteras, Choti Diwali, Lakshmi Puja (the main day of Diwali), Govardhan Puja, and Bhai Dooj. Each day has its own rituals and cultural significance, with activities including cleaning and decorating homes, lighting lamps (diyas), offering prayers to Goddess Lakshmi and other deities, feasting on sweets, social visits, and fireworks. The five-day span marks the triumph of light over darkness and good over evil and also celebrates the Hindu New Year in many regions. The core day is usually the third day when Lakshmi Puja is performed, and homes are illuminated with lamps, symbolizing prosperity and auspiciousness. The remaining days involve preparations before and family/community activities afterward. This duration and sequence of events are widely observed across India and in Hindu communities worldwide, with some regional variations in the specific customs and names of each day’s celebration.
