होली है

Holi is an annual festival celebrated on the day after the full moon in the Hindu month of Phalguna (early March). It celebrates spring, commemorates various events in Hindu mythology and is a time of disregarding social norms (because all end up colored, no matter what their social status) and indulging in general merrymaking. Holi is probably the least religious of Hindu holidays. During Holi, Hindus attend a public bonfire, spray friends and family with colored powders and water, and generally go a bit wild in the streets (from religionfacts.com).
