The Ugadi festival marks the beginning of the new year for those living between the Kaveri and Vindhyas rivers and those following the lunar calendar of southern India, especially in the states of Karnataka, Andhra Pradesh and Maharashtra. The calendar dates from the Shalivahana era that would have been built by the great legend of Shalivahana. King Shalivahana was also called Gautamiputra. Satakarni is responsible for initiating the Shalivahana era.
The lunar calendars have a cycle of sixty years and a new year begins the day of Ugadi/Yugadi at Chaitra Sudhdha Paadyami. After the completion of every sixty years, the calendar begins with a new year. During the festival, it is believed that the spring season has reached its fullness and everywhere you can see the colors of the festivals. The new leaves growing in the trees are incredibly beautiful and you can see the zeal and emotion in the hearts of people celebrating Ugadi. However, Lord Shiva cursed Lord Brahma saying that he would never be worshiped, but that in Andhra Pradesh this Ugadi celebration is specifically celebrated in honor of Lord Brahma. According to ancient tales, it is believed that Lord Maha Vishnu took the form of Matsya. On Ugadi day, people clean their homes and surroundings and decorate the entrance of their house with mango leaves. And also people buy new clothes for themselves and their family members.
