Sarasvatī is the goddess of speech, learning and music, the river goddess of the Ṛgveda who became the patron of every art. Vasanta Pañcamī, the fifth day of the bright half of Māgha, is kept as her day and also marks the first stirring of spring (vasanta), when mustard fields turn yellow.
Because learning begins with her blessing, children are often taught to write their first letters on this day, and students place their books and instruments before her for worship.
