Apart from the universally celebrated festivals like Dussehra, Diwali and Ganesh Chaturthi, there are others that are observed in specific communities or geographical areas. Hindu holidays are also confined to particular regions by the importance a certain god enjoys. Worship of Kartikeya (as during the festival of Skanda Shashti) is predominant in Tamil Nadu, where the god is considered a patron of the region. Onam is a good example of a festival that is celebrated solely by Keralites. Another interesting aspect of Onam is that it is perhaps the only major Hindu festival that celebrates the reign of an asura king, although a benevolent one.
