With the exception of the Julian day system, used primarily by astronomers, calendars are based on various inaccurate time periods given names such as year or month. Such periods are not of the same duration (length) as those used for scientific purposes.
Most calendars are solar, lunar or luni-solar and are usually, but not always, synchronised with the sun or moon cycles.
