Holi (Hindi: होली), is a religious spring festival celebrated by Hindus. Holi is also known as festival of Colours. It is primarily observed in India, Bangladesh, Pakistan,Nepal,  and countries with large Indic diaspora populations following Hinduism, such as Suriname, Malaysia, Guyana, South Africa, Trinidad, United Kingdom, United States, Mauritius, and Fiji. It is also known as Doḷajāta (Oriya: ଦୋଳଯାତ) in Orissa and Dol Jatra (Bengali: দোলযাত্রা) or Basantotsav (“spring festival”) (Bengali: বসন্তোৎসব) in West Bengal. The most celebrated Holi is in the Braj region, in locations connected to the Lord Krishna: Mathura, Vrindavan, Nandagaon, and Barsana. These places have become tourist destinations during the festive season of Holi. Large parts of South India, however, do not celebrate Holi with the same fervour as in other parts of the country.
Every year, thousands of Hindus participate in the festival Holi. The festival has many purposes. First and foremost, it celebrates the beginning of the new season, spring. It also has a religious purpose, commemorating many events that are present in Hindu mythology. Although it is the least religious holiday, it is probably one of the most exhilarating ones in existence. During this event, participants hold a bonfire, throw colored powder at each other, and celebrate wildly.
Originally, it was a festival that commemorated good harvests and the fertile land. In addition to celebrating the coming of spring, Holi has even greater purposes. Hindus believe it is a time of enjoying spring’s abundant colors and saying farewell to winter. Furthermore, Holi celebrates many religious myths and legends.
