Saraswati is the Hindu goddess of learning, music and art. Saraswati Puja is perhaps another "signature festival" of Bengal.
The puja is performed is almost all schools, colleges, educational institutions as well as households. There is some community Saraswati Puja as well.
Many young girls have their first shot at wearing the "sari" (traditional Indian dress) during the Saraswati Puja. The young "para" guys go out on the streets collecting donations ("chanda") from the neighbourhood uncles to perform the puja.
There is also a ritual of "hate khari"
