Most calendars are in some way based on either the solar (Sun) or the lunar (Moon) cycle; some are based on both. Of the commonly used calendars:* The Gregorian calendar - the most widely used calendar worldwide - is based on the Sun. That is, the length of the year is based on the Sun; but the start of the year and the months is not related to any particular astronomical event.
* The Jewish calendar is based on both the Moon and the Sun. As far as I know, it's the only widely used calendar that is based on BOTH. Some years have 12 months, others have 13 months.
* The Muslim calendar is based on the Moon. A muslim year is about 11 days shorter than a Gregorian (solar) year.
* Many other calendars are based on the Sun.

The three primary types of calendars are the solar, lunar and lunisolar. Calendars that are based on the earth's revolution around the sun without regard for the moon's monthly cycle, like the Gregorian calendar used in most if not all Christian countries, are called solar calendars. Calendars that are based only on the moon's revolution around the earth without compensation for the seasonal effects of the earth's solar orbit, like the Hijra used in Islamic countries, are called lunar calendars. Lunisolar calendars, like the Jewish calendar, have months that start at the times of the new moon but also periodically (seven times every nineteen years) add leap months in an attempt to stay in sync with the solar cycle as well.
