Month facts for kids
A month is an amount of time used with calendars. It is about 1/12th of a year. It is a little longer than a natural synodic orbital period of the moon, ca. 29.5 days. Lunar calendars use the natural synodic month. For some purposes astronomers use the sidereal month of 27.3 days.
