What were the three seasons of ancient Egypt?

The three seasons observed in ancient Egypt were Akhet, Peret and Shemu. The seasons were associated with the three phases of farming as well as the rise and fall of the Nile River.

The first season of ancient Egypt, Akhet, marked the period between June and September when the banks of the Nile River flooded, with flood waters bringing fertile mud and silt to the region. It was followed by Peret, lasting from October to February, during which crops were planted and grown. The last season of the ancient Egyptian calendar was Shemu, which marked the harvest period that took place between March and May.
