Religion plays a significant role in the daily life of Indian Christians. India ranks 15 among countries with highest church attendance. Religious processions and carnivals are often celebrated by Catholics. Cities with significant Christian populations celebrate patron saint days. As in other parts of the world, Christmas is the most important festival for Indian Christians. Anglo-Indian Christmas balls held in most major cities form a distinctive part of Indian Christian culture. Good Friday is a national holiday. All Souls Day is another Christian holiday that is observed by most Christians in India. Most Protestant churches celebrate harvest festivals, usually in late October or early November. Christian weddings in India conform to the traditional white wedding. However it is not uncommon for Christian brides particularly in the south to wear a traditional white wedding sari instead of a gown. The vast majority of Protestant women and to a lesser extent Catholic women in India do not wear the bindi (red dot on the forehead) and can therefore be easily distinguished from their Hindu counterparts.
