Holi

Every spring, people across India and around the world celebrate the Hindu festival Holi, throwing colored water and powders on one another in joyous celebration. On this one day—the full-moon day of the Hindu month of Phalguna—societal rankings such as caste, gender, age, and status are eschewed in the spirit of making merry together, and everyone is fair game to be doused with color.
