The major secular holidays are Independence Day (August 15) and Republic Day (January 26). The most popular religious festivals celebrated over the greater part of India are Vasantpanchami, in honour of Sarasvati, the goddess of learning; Holi, a time when traditional hierarchical relationships are forgotten and celebrants throw coloured water and powder at one another; Dussehra, when the story of the Ramayana is reenacted, and Diwali (Divali), a time for lighting lamps and exchanging gifts.
