The day starts with viewing the 'kanni' (the auspicious sight) at dawn, in the expectation that beginning the New Year by looking at auspicious or favourable things will bring good fortune throughout the year. The auspicious things include, gold and silver jewellery, betel leaves, nuts, fruits and vegetables, flowers, raw rice and coconuts. This is followed by the ritual bath and a visit to the temple to pray for a prosperous and happy New Year. After which, the Panchangam (almanac) is read. The ladies adorn the entrances of their houses with ‘Kolam’ (design made with rice flour) and deck the doorway with mango leaves. A grand Car Festival is held at Tiruvadamarudur near Kumbakonam every year on April 14th. Also during the month of Chitthirai the marriage of Goddess Meenakshi to Lord Sundareswarar is celebrated as ‘Chitthirai festival’.
The highlight of the festival is the 'Maanga Pachadi' (a dish made of raw mangoes, jaggery and neem flowers), which is at the same time sweet, sour and bitter. This signifies all the different aspects of our life.
April 14th also happens to be the Bengali New Year Day, Naba Barsha, which begins with the ‘Prabhat Pheries’ (an early morning procession) with songs and dances welcoming the New Year. In Kerala ‘Vishu’ is celebrated by Malayalees commemorating the beginning of the astronomical New Year in the Malayalam Calendar.
