Diwali or the ‘festival of lights’ is one of the most significant festivals for Hindus, Sikhs, and Jains. It comes once a year but its preparations start months in advance. In recent years, people from all religions have started celebrating it. Hindus celebrate the return of Lord Rama on Diwali and Sikhs celebrate the return of Guru Hargobind Singh on Bandi Chhor Divas.
