Calendar from Cham manuscript, early 20th century

An image of the Cham calendar from an early 20th century Cham manuscript. The column on the left and top row indicate measurements of months of the calendar drawn from the Islamic lunar calendar. Numerals written in Cham script in the middle are symbolic of the Cham Hindu solar calendar. The combination of the lunar-awal and solar-ahiér calendars is intended to promote social harmony and avoid the tensions alluded to in the poem Ariya Bini Cam. The origins of the calendar are said to be in the 17th century reign of an upland ruler of Cham communities, Ppo Romé. To this day, the calendar is used to decide on the appropriate times for weddings, funerals, and high holidays, so that the resources of the Cham community are not overly strained by having such occasions overlap with one another.
