Here is your short paragraph on Chaitra Pratipada:
This is observed mainly in Maharashtra on the first day of Chaitra (March- April) as the New Year Day. It is also called Gudi Parva.
According to Shalivahana Saka, it is the first month and the myth has it that on this day the world was created by Lord Brahma and the day is, therefore, dedicated to him.
Houses are cleaned on the occasion and the entrance to the houses are gaily decorated.
For Maharashtrians, the New Year begins on this day, i.e., in the month of Chaitra (March-April) and Lord Brahma is worshipped on the occasion that is also known as ‘Gudi Parva’.
