The traditional Burmese calendar is a lunisolar calendar based on both the phases of the moon and the motion of the sun. Within each month of the Burmese calendar, a major festival, often Burmese Buddhist in nature, is held. Despite its religious and cultural importance, the traditional calendar has been largely abandoned, particularly in major urban areas, in favour of the Gregorian calendar. Many newspapers continue to utilise traditional month names, but purely in ceremonial fashion.
