Introduction
The Egyptian calendar, often referred to as the Civil Calendar, is one of the oldest known timekeeping systems. Developed around 4236 BC, it played a significant role in ancient Egyptian society, primarily for regulating agricultural activities and religious festivals. Its unique structure, consisting of 12 months of 30 days each, along with an additional five “epagomenal” days, marked a considerable advancement in the understanding of time in history.
