Mathematics in Acholi is a significant cultural project aimed at preserving traditional knowledge that has existed informally within the Acholi community for generations. As a Luo-Nilotic ethnic group primarily residing in Northern Uganda and Southern Sudan, the Acholi have long practiced mathematics through oral traditions, deeply embedded in their daily activities, cultural events, and social structures. Although this knowledge has never been formally recorded, it has played a crucial role in areas such as agriculture, trade, and timekeeping, demonstrating a sophisticated understanding of mathematical principles like counting, measuring time, and tracking cycles. 

Acholi timekeeping is deeply embedded in the rhythms of nature and the cultural practices that sustain the community, offering a fascinating and distinct lens for mathematical applications. The Acholi people do not view time in the conventional linear sense but instead see it as closely tied to natural events, such as sunrise (ceng ele), sunset (ceng too), and the different phases of the moon (lack due). These markers serve as the primary means of organizing the day and structuring various activities. This cyclical understanding of time offers unique mathematical insights, as these natural phenomena can be quantified through durations, intervals, and periodic cycles. For example, the workday of a farmer, which typically spans from sunrise to sunset (about 12 hours), can be subdivided into proportional segments for specific tasks, allowing for the application of fractions and time division in a real-world context.
