The festival of Onam is celebrated throughout the state of Kerala. Onam is marked by happiness, excitement and enjoyment among all sections of people. Onam is celebrated as an outcome of reasons that have to do with mythology as well as old agrarian practices. 

• One reson is to wotship Lord Vishnu . Lorrd Vishnu accepted Mahabali's wish to let him visit his subjects once a year and that day of his return has come to be celebrated as Onam
• Other reason for celebrating Onam is because it is the time of the year when a good harvest has been gathered all over Kerala, resulting in plenitude and happiness.

The celebrations for Onam are held for ten days, beginning with the atham asterism in the month of Chingam (August / September) as per the local calendar. This year, Onam is celebrated on September 15, 2024.
