How were the ancient egyptians’ advancements in the fields of astronomy and mathematics to farmers?

Ancient Egyptian civilization was an advanced culture in terms of astronomy and mathematics. However, these were not only scholarly pursuits. These developments had an important impact in the everyday activities of common people. For example, in agriculture.

One of the most significant advancements of the Egyptian civilization was the development of an irrigation system. This involved the construction of drainage canals and other aspects of hidraulic engineering. These extensive systems would not have been possible without their knowledge of mathematics.

There were significant achievements in the field of astronomy as well. Based on their observations of the sun and the moon's movements, the Egyptians developed an accurate calendar organized in twelve 30-day months, three seasons of four months each, plus an extra five days, giving a 365-year day but with no way of accounting for the extra quarter day each year. Day and night were split into 24 units. This allowed people to farm the land more successfully.
