Weton

Weton is a traditional Javanese system used to determine a person's birth moment and auspicious timing by combining two cyclical calendars: the 7-day week and the 5-day Pasaran cycle. The 7-day week names (Minggu, Senin, Selasa, Rabu, Kamis, Jumat, Sabtu) are paired with one of five Pasaran days (Legi, Pahing, Pon, Wage, Kliwon) to produce 35 possible weton combinations, such as Senin Legi or Selasa Kliwon.

Calculation: A person's weton is said to influence personality traits, fortunes, and compatibility. In daily life, people consult weton for choosing wedding dates, business openings, or auspicious days; for couples, weton comparison (weton pasangan) is used to assess harmony.

Cultural context: Weton is part of Javanese calendars and astrology and remains a common reference in Java, especially in Central and East Java. It coexists with other traditional practices and is often observed in family rites and ceremonies, even as modern urban life reduces its prominence for some.

Criticism and interpretation: Weton is a belief system without empirical support; it is considered a cultural tradition rather than a science. The practice varies by region and family, with some treating it as a guide for timing rather than strict rule.
