tradition of weton calculation practice in Kedarpan Village as a requirement for
marriage has been carried out for generations. This tradition is carried out before
the bride and groom have the wedding. Precisely, it is before the bride and groom
have the engagement. Javanese weton calculation are often used to determine
mate and wedding day. The first thing to do in calculating the weton to determine
the requirements for marriage in Kedarpan village is to know in advance the
birthdays of both bride and groom. It is to find out the neptu or the value of the
count based on the day of their birth. Afterwards, the calculation is done after the
value is found. Meanwhile, in terms of prohibition, if the results of the weton
calculation match, it can certainly be continued. However, if the results are not
suitable, it cannot be continued. It is feared that it will cause undesired effects. In
terms of changes in society towards the calculation of weton in Kedarpan Village,
the existing traditions in the community are starting to be abandoned due to
modernization. There are several factors that affect the course of a process of
social change such as technological progress, the influence of other cultures, the
desire to progress and develop, a community open system, and people's
dissatisfaction about certain things that are considered irrelevant in the present.
