Knowledge is very important for Balinese. Every Saniscara, Umanis, Wuku Watugunung, they celebrate Saraswati Day, the knowledge day. It is based on the Pawukon (Balinese calendar) system and the Saniscara (seven day cycle). Saraswati in Bali will be held on Saturday, June 25th this month.

The name Saraswati came from "Saras" meaning flow and "wati" meaning a women. So, Saraswati is symbol of knowledge, its flow (or growth) is like a river and knowledge is very interesting, like a beautiful women.

Saraswati is the Goddess of Knowledge, symbolized by a beautiful woman with four hands, riding on a white swan among water lilies to tell humanity that science is like a beautiful woman. Her hands hold a palm leaf; a lontar, (a Balinese traditional book which is the source of science or knowledge); a chain (genitri with 108 pieces) symbolising that knowledge is never ending and has an everlasting life cycle; and a musical instrument (guitar or wina) symbolising that science develops through the growth of culture. The swans symbolise prudence, so that one's knowledge may distinguish between good and evil and the water lilies (Lotus) are symbols of holiness. The Lotus flower is the holiest for Balinese.

In the afternoon of Saraswati day we are not permitted to read or write the book because all the books are offered. In the evening, called Malam Sastra, people read books (especially religious books) in their houses or in the temple.

- Pangredanan (the day before Saraswati)
  This is the day of preparation. All the books and lontar are collected together, cleaned and dusted.
- Saraswati Day
  Saraswati day itself is celebrated by the Balinese people bringing offerings to their holy books and scrolls in their houses, while students   celebrate it at school, usually in the morning, and the office-workers in their office. The philosophy of Saraswati day is that the most   important thing for human life is knowledge.
- Banyu Pinaruh
  The day after Saraswati Day is Banyu Pinaruh day. "Banyu" means water and "Pinaruh" mean wisdom. In other words, we must have wisdom which   always flows like water and which is useful for human kind. We pray for Dewi Saraswati (manifestation of God) to give us cleverness and   wisdom. The people usually take a bath in the sea or a lake or river and drink traditional medicine which is made from many various leaves   which is very good for our health.
