Muslim holidays are prominent as Islam is the state religion; ''Hari Raya Puasa'' (also called ''Hari Raya Aidilfitri'', Malay for Eid al-Fitr), ''Hari Raya Haji'' (also called ''Hari Raya Aidiladha'', Malay for Eid ul-Adha), ''Maulidur Rasul'' (birthday of the Prophet), and others being observed. Malaysian Chinese celebrate festivals such as Chinese New Year and others relating to traditional Chinese beliefs. Wesak Day is observed and celebrated by Buddhists. Hindus in Malaysia celebrate ''Deepavali'', the festival of lights, while ''Thaipusam'' is a religious rite which sees pilgrims from all over the country converge at the Batu Caves. Malaysia's Christian community celebrates most of the holidays observed by Christians elsewhere, most notably Christmas and Easter. In addition to this, the Dayak community in Sarawak celebrate a harvest festival known as ''Gawai'', and the Kadazandusun community celebrate ''Kaamatan''. Despite most festivals being identified with a particular ethnic or religious group, celebrations are universal. In a custom known as "open house" Malaysians participate in the celebrations of others, often visiting the houses of those who identify with the festival.
