Hari Raya Haji is a time of prayer and remembrance. Hindus celebrate the Tamil New Year sometime in mid-April, while other Indian groups observe New Year at different times. Thaipusam is a penitential Hindu festival popular with Tamils. This is the festival where Indians walk several miles carrying kavadis that pierce their bodies, to thank their gods for answering their prayers. Deepavali, the Festival of Lights, is celebrated by Hindus and Sikhs .
Christian festivals have a fairly strong following in Singapore.
Christmas in particular is heavily commercialised. The entire stretch of the Orchard Road shopping belt is lit up with decorative lights from November to early January. The multiracial mix is such that most Singaporeans celebrate more than just the festivals of their own ethnic group. So a Chinese Christian might go to church, but also partake in the cultural rites in some Chinese festivals. Even when they don't actually celebrate certain festivals, many will visit their friends and neighbours from other ethnic communities to join in the fun.
