In the Javanese calendar (Anno Javanica) there are two types of day names, namely pancawara day and saptawara day. Pancawara is a five-day cycle, such as: Legi (Manis), Paing, Pon, Wage and Kliwon. While Saptawara is a seven-day cycle, such as Monday, Tuesday, Wednesday, Thursday, Friday, Saturday and Sunday. But in the Masehi calendar does not recognize this pancawara cycle. In this paper intends to determine the day of the pancawara in the Masehi calendar. For the determination of the pacawara day in the Masehi calendar, in this paper was construct mathematical formulation of the name of the day pancawara for a specific date on the Masehi calendar The results of the discussion obtained two alternative formulas to determine the name of the pancawara day in the Masehi calendar. So it can complement two formulas that have been formulated by previous research.
