</ref> lunisolar calendars track more or less the tropical year whereas the Buddhist and Hindu lunisolar calendars track the sidereal year. Therefore, the first three give an idea of the seasons whereas the last two give an idea of the position among the constellations of the full moon. The Tibetan calendar was influenced by both the Chinese and Hindu calendars. The [[Germanic calendar|English also used a lunisolar calendar]] before their conversion to Christianity {{Fact|date=May 2007}}.The twelve-month, thirty-day Hawaiian calendar incorporates the same sophisticated astronomy used by the ancient Polynesians to navigate throughout the Pacific and details when plants should be sown and fish caught. <ref>http://www.nokaoimagazine.com/article.aspx?issue=Vol12%20No1&article_name=Hawaiian_moon_calendar</ref>
The [[Islamic calendar]] is a [[lunar calendar|lunar]], but not a lunisolar calendar because its date is not related to the sun. The [[Julian Calendar|Julian]] and [[Gregorian Calendar]]s are [[solar calendar|solar]], not lunisolar, because their dates do not indicate the moon phase
== Determining leap months ==

A rough idea of the frequency of the intercalary or leap month in all lunisolar calendars can be obtained by the following calculation, using approximate lengths of months and years in days:
* Year: 365.25, Month: 29.53
* 365.25/(12
* 1/0.0307 = 32.57 common months between leap months
* 32.57/12
A representative sequence of common and leap years is ccLccLcLccLccLccLcL, which is the classic nineteen-year [[Metonic cycle]]. The Buddhist and Hebrew calendars restrict the leap month to a single month of the year; the number of common months between leap months is, therefore, usually 36, but occasionally only 24 months. Because the Chinese and Hindu lunisolar calendars allow the leap month to occur after or before (respectively) any month but use the true motion of the [[sun]], their leap months do not usually occur within a couple of months of [[perihelion]], when the apparent speed of the sun along the [[ecliptic]] is fastest (now about 3 January). This increases the usual number of common months between leap months to roughly 34 months when a doublet of common years occurs, while reducing the number to about 29 months when only a common singleton occurs.
