The merriment started from midnight as bells tolled and worshippers thronged churches and cathedrals decorated with twinkling lights for the midnight service where priests delivered Christmas messages.
People, attired in their best, bonded in prayer and mirth as sparkling Christmas trees and colourful gift items adorned market places that wore a festive look.
Even non-Christians were seen celebrating the festival as long queues were seen outside bakeries to buy cakes and cookies on the occasion. People used WhatsApp, Facebook and other modern means of communication to send Christmas greetings to their families and loved ones.
In Delhi, a large number of revellers reached prominent shopping centres like Connaught Place and tourist spots like India Gate to enjoy the festivities on the holiday.
The yuletide spirit also swept West Bengal as revellers lined up outside the iconic Nahoum's confectionery at New Market in Kolkata to gorge on sumptuous Israeli dishes and cakes.
