Today people in India mark Holi, also known as the Festival of Spring or the Festival of Colors. The vibrant Hindu tradition is celebrated at the end of Winter, on the last full moon day of the lunar month Phalguna — which is today! Similar to Mardi Gras, during Holi social restrictions are loosened. In India, Hindus from all classes and both sexes celebrate together, and people are expected to act a little wild, throwing colorful dust on each other to mark the end of a cold and dark Winter.
