What was the purpose of the solar calendar in ancient Egypt?

The solar calendar in ancient Egypt was primarily designed to track agricultural seasons. This calendar was essential for determining the timing of the annual flooding of the Nile River, which was crucial for farming. The flooding provided the necessary irrigation and nutrients for crops, directly influencing agricultural output.

While the solar calendar might have also played a role in tax collection and the administration of land, its main purpose was to ensure that agricultural activities were aligned with the natural cycles of the Nile and the seasons. Thus, farmers and the broader society could prepare for planting and harvesting, making it a vital tool for sustaining the economy and food supply of ancient Egypt.
