In ancient Egypt, the cattle count was one of the two main means of evaluating the amount of taxes to be levied, the other one being the height of the annual inundation. A very important economic event, the cattle count was controlled by high officials, and was connected to several cultic feasts. In addition it served as a means of dating other events, with the entire year when it occurred being called "year of the Xth cattle count under the person of the king Y". The frequency of cattle counts varied through the history of ancient Egypt; in the Old Kingdom it was most likely biennial, i.e. occurring every two years, and became more frequent subsequently.
