{{දින දසුන්}}A '''lunisolarචන්ද්ර calendarසූර්ය දින දසුන''' is aයනු [[calendar]] in many [[culture]]s whose date indicates both the [[moonචන්ද්ර phaseකලා]] and the time of the solar [[year]]. If the solar year is defined as a [[tropical year]] then a lunisolar calendar will give an indication of the [[season]]; if it is taken as a [[sidereal year]] then the calendar will predict the [[constellation]] near which the [[full moon]] may occur. Usually there is an additional requirement that the year have a whole number of months, in which case most years have 12 months but every second or third year has 13 months.
