The keyword phrase "tanggal 11 september 2025 kalender jawa" functions as a noun phrase. It specifies a singular, definite point in time. The Gregorian date of Thursday, 11 September 2025, corresponds to the Javanese calendar date of Kamis Kliwon, 17 Bakda Mulud 1959 Jimawal.
The Javanese date is a composite of several distinct calendrical systems. The term "Kamis Kliwon" is the weton, which combines the day from the 7-day week (Saptawara), which is Kamis (Thursday), with the day from the 5-day market week (Pancawara), which is Kliwon. The date itself is the 17th day of the month Bakda Mulud, the fourth month in the Javanese lunar year. The year is designated as 1959 Jimawal, where 1959 is the year in the Javanese Saka era, and Jimawal is the name of the year within an 8-year cycle known as a windu. Additionally, this date falls within the wuku cycle of Manahil, a 210-day period used for numerological and divinatory purposes.
In cultural practice, the components of a Javanese date, especially the weton, are used for divination and determining character traits based on traditional Javanese belief systems, often documented in texts known as primbon. The weton Kamis Kliwon has a numerical value (neptu) of 16, derived from adding the value of Kamis (8) and Kliwon (8). This value is used in complex calculations to assess marital compatibility, determine auspicious days for significant events like weddings or building a house, and to interpret an individual's destiny and personality.
