This study discusses the way of Cigugur traditional community in Indonesia doing their calculating on farming. By using realist ethnography, this study reports objectively the information that collected from participant in the Cigugur traditional communitythrough observation, interviews, documentation, and field notes. The findings from this study show that the farming system carried out by the community used formal mathematics principles. The hari cycle and pasaran cycle in Sundanese are as the same as the concept of relations and functions in mathematics. The function in question is injective function. The results of the relations between day “ hari ” and “ pasaran” can be expressed in an order pair to pair. To determine a finest day, the mathematical concepts used by the Cigugur traditional community are the concepts of addition and the concept of comparison. The sum concept is used to add the values of each day to the value of each pasaran. Meanwhile, the concept of comparison is used to compare the value of the sum results with the criteria for determining the finest day for tandur . Ethnomatematics provides different perspectives regarding mathematical conceptuality.
