The calendar system is a creation of human civilization, developed mostly based on astronomy. Various calendars have also been known in Nusantara since ancient times, and so far are still widely used in different regions, although the present Indonesian civil calendar utilizes the International Gregorian calendar system. <br /> People in Java have their own calendar system which has been used for several centuries. There are several terminologies such as year, month, day, or week adopted in Java as units of time keeping in their calendar system. Javanese calendar appears to be influenced by other previous calendars mainly by the Indian calendar. Related to this hypothesis, this final project reviews and discusses astronomical aspect in the Javanese calendar as well as some other calendar systems through literature study and consultation with experts in the calendar. From the corresponding analysis, we found that the inscriptions, which were found scattered mostly in Java, generally contain fairly detailed on the date and hence could provide direct information about the calendar system that was used and adopted in a place and time in Java. Saka has been widely known and used continuously. Therefore, the system of Hindu (Indian) calendar affects considerably the Javanese system, which was also mixed with astrological beliefs. We also found that the Javanese calendar develops its own specific unit of time keeping as well and later it was also heavily influenced by the cycle of the seasons, called the Pranatamangsa system.
