Holi is a popular, Hindu spring festival, observed in India, also called the Festival of Colours. On the first day, bonfires are lit at night to signify burning Holika. The second day, known as Dhulandi, people spend the day throwing coloured powder and water at each other.
Although a Hindu celebration, other religions in India celebrate it as well. In fact, some of the best Holi celebrations are said to happen in Punjab, where Hindus and Sikhs celebrate together. This celebration in Punjab typically involves Dholi's and other musical instruments as kids and adults celebrate.
