Bali celebrates the Hindu Goddess of knowledge, Saraswati. The celebration is known as Sanghyang Aji Saraswati Day.
Dewi Saraswati is the Goddess of knowledge. She holds in her four hands a musical instrument, a book, a prayer mala, and a blue waterlily. Balinese use this day to give thanks for knowledge, music, and culture. Her holiday comes every 210 days on our Balinese calendar with 6 equal months of 35 days each.
