Some religious festivals, like Christmas, are fixed to a single point in the calendar. Others move, usually according to the lunar calendar. Passover is one of the most important religious celebrations in the Jewish tradition. It coincides with the Christian festival of Easter. For the Sikh community, the Vaisakhi festival is one of the most important. For Hindus, Diwali is among the most keenly anticipated. Eid al-Fitr is a significant festival for Muslims while Esala Perahera is celebrated within certain Buddhist communities, notably in Thailand.
