Traditionally, We Indians celebrate Diwali by decorating our homes with lights (diyas), cooking tasty food, buying new clothes, and exchanging gifts and sweets with others. In addition, people worship lord Lakshmi (God of Money) and Lord Ganesha (God of Success) on this day. Diwali is a five days long festival.
Diwali, a five-day festival, includes Dhanteras, Naraka Chaturdashi, Lakshmi Pooja, Govardhan Pooja, and Bhai Dooj. We Indian start cleaning our homes two weeks before Diwali and remove old unused materials from our homes because it is said that on the day of Diwali, Lord Lakshmi visits our homes. So, people clean their homes two weeks before Diwali.
Dhanteras is the beginning of the five-day Diwali festival. On this day, there is an Indian tradition to buy items for the Diwali festival. i.e., Lord Ganesh statue (murti), Lord Lakshmi statue (murti), clothes, and sweets.
On the Day of Diwali, We Indians decorate our courtyards with rangoli, and in the evening, we dress our new clothes and worship lord Ganesha, lord Lakshmi and lord hanuman. After the worship, kids used to burst firecrackers.
Besides this, firecrackers are unsuitable for us because they increase air and sound pollution. So, we should use eco-friendly firecrackers so they pollute less.
