A religious observance practiced in
India, Bangladesh and Nepal practiced on the last full moon day of the lunar month of "Phalguni "in the Hindu calendar, which occurs around the beginning of Spring in
March. It is also practiced by the
Indian Hindu/Sikh/Jain diaspora in Singapore,
Malaysia, Sri Lanka, Burma, Maldives, Mauritus and in western countries like the US and Canada.
It is known as the festival of colors, since Indians celebrate the day by smearing colored powder on each other as a gesture of brotherhood and goodwill.
Christian extremists (like this
guy "John Francois" with his misspellings and misgivings about Holi) from the Northeastern parts of India hate this festival because they are illiterate nuts who have been radicalized by racist missionaries from abroad.
