People had special sesame oil bath and wore new clothes. Relatives and friends asked one another "Ganga Sthanam Aachha?" - is bathing with the water of holy river Ganga over?
People exchanged sweets, savouries and the special Diwali Leghium - a herbal jam - with friends, neighbours and relatives, and celebrated the day with fervour.
In many houses, people exchanged greetings over the phone.
"The day started with bursting of crackers with my kids. After the traditional oil bath we went to the nearby temple to offer prayers," J. Muralidharan, a resident of Chennai, told IANS.
While children started their day bursting crackers, adults conducted pujas in their homes and temples.
