Christmas Eve is the night before Christmas on December 24. It starts the celebration of the birth of Christ in the Christian religion.
Christians, especially Roman Catholics, in India celebrate Christmas Eve with a midnight mass church service. The service is followed by a family feast and giving/receiving of gifts. It is a restricted holiday in India where all government and businesses remain open.
Christians in India make up 2.3% of the population which equals to over 25 million. Christmas is a small festival compared to other religious holidays.
