Lunar Calendar

A lunar calendar is a calendar that is based on cycles of the lunar phase. Because there are about twelve lunations (synodic months) in a solar year, this period (354.37 days) is sometimes referred to as a lunar year.

A common purely lunar calendar is the Islamic calendar or Hijri Qamari calendar. A feature of the Islamic calendar is that a year is always 12 months, so the months are not linked with the seasons and drift each solar year by 11 to 12 days. It comes back to the position it had in relation to the solar yearapproximately every 33 Islamic years. It is used mainly for religious purposes, and in Saudi Arabia it is the official calendar. In other systems, a lunar calendar may include extra months added that synchronize it with the solar calendar.

Famous quotes containing the words lunar and/or calendar:

    A bird half wakened in the lunar noon
    Sang halfway through its little inborn tune.
    Robert Frost (1874–1963)

    To divide one’s life by years is of course to tumble into a trap set by our own arithmetic. The calendar consents to carry on its dull wall-existence by the arbitrary timetables we have drawn up in consultation with those permanent commuters, Earth and Sun. But we, unlike trees, need grow no annual rings.
    Clifton Fadiman (b. 1904)
