Cambodia has numerous public holidays, including memorial holidays and religious holidays of Buddhist origin. The Khmer traditional calendar, known as ChântôkôtÃÂ, is a lunisolar calendar although the word itself means lunar calendar. While the calendar is based on the movement of the moon, calendar dates are also synchronized with the solar year to keep the seasons from drifting.
Therefore, some public holidays are subject to change every year based on the lunar calendar.
