There are two types of months, or calendars, that astronomers use: the lunar and the solar. The solar months are the more familiar calendar and one example of a solar month is January. Lunar months are dependent on the cycles of the moon. One month is considered the time it takes for two occurrences of the same cycle to occur, such as two new moons or two full moons.
