The Wright family rhythm forecaster is a duplex circular slide chart which consists of two concentric circles and can be used for predicting ovulation periods and calculating fertility. The inner or smaller slide features, in the centre, basic instructions on how to use the chart accurately as well as a graph for tabulating results. The instructions are encircled by a series of sections indicating periods of fertility and sterility, based on cycles of 24 to 20-27 days. The outer wheel displays the calender year from January to December. The reverse of the forecaster is similar to the front, with the cycles ranging from 24-28 to 32-36 days.
