The Javanese weton for September 11, 2025, is Kamis Wage. A weton is a specific day designation within the traditional Javanese calendar system, which results from the combination of a day from the seven-day week (Saptawara) with a day from the five-day market week (Pancawara).
The calculation of a weton involves identifying the corresponding day in two parallel cycles. The first cycle, the Saptawara, is a seven-day week adopted from the Gregorian and Islamic calendars, where the day in question, September 11, 2025, is a Thursday (Kamis). The second cycle is the indigenous Javanese Pancawara, a five-day market week consisting of Legi, Pahing, Pon, Wage, and Kliwon. For this date, the Pancawara day is Wage. The combination of these two cycles creates a 35-day cycle (7 5), known as a selapanan, where each unique weton, such as Kamis Wage, occurs once.
In Javanese culture and the system of divination known as Primbon, each weton has a numerical value called a neptu, which is used to interpret personality traits, determine compatibility, and find auspicious timing for major life events. The neptu for Kamis Wage is calculated by summing the values of its constituent days: Kamis has a value of 8, and Wage has a value of 4. Therefore, the total neptu for this weton is 12. This value serves as a basis for various divinatory calculations concerning an individual's fortune, character, and life path.
