When did the great pyramid workers work?

The workers who built the Great Pyramid of Giza primarily worked during the annual flooding of the Nile, which occurred from June to September. This seasonal flooding made farming impossible, so laborers, often skilled artisans and laborers rather than slaves, took part in the pyramid construction as a form of employment. They worked in organized teams, and the construction likely took around 20 years to complete, with work continuing until around 2560 BCE.
