The lunisolar calendar is a combination of the two, and is used in some cultures. The Chinese calendar is a lunisolar calendar, as is the Hindu calendar. The Islamic calendar is a lunar calendar, with days beginning at sunset.There are also many other calendar types in use around the world, often specific to certain cultures or religions.
