The spring festival Holi, also known as the Festival of Colours, is observed by followers of which religion?

Holi is a Hindu spring festival celebrated in India and Nepal, also known as the "festival of colours" or the "festival of love". The festival signifies the victory of good over evil, the arrival of spring, end of winter, and for many a festive day to meet others, play and laugh, forget and forgive, and repair broken relationships. It is also celebrated as a thanksgiving for a good harvest.

It lasts for a night and a day, starting on the evening of the Purnima (Full Moon day) falling in the Vikram Samvat Hindu Calendar month of Phalguna, which falls somewhere between the end of February and the middle of March in the Gregorian calendar. The first evening is known as Holika Dahan or Chhoti Holi and the following day as Holi, Rangwali Holi, Dhuleti, Dhulandi, or Phagwah.

Holi is an ancient Hindu religious festival which has become popular with non-Hindus in many parts of South Asia, as well as people of other communities outside Asia. In recent years the festival has spread to parts of Europe and North America as a spring celebration of love, frolic, and colours.
