Thout (Coptic: Ⲑⲱⲟⲩⲧ, [tʰoːuːt]), also known as Thoth (Greek: Θωθ, Thōth) and Tut (Arabic: توت), is the first month of the ancient Egyptian and Coptic calendars. It lies between 11 September and 10 October of the Gregorian calendar. The month of Thout is also the first month of the Season of Akhet (Inundation) in Ancient Egypt, when the Nile floods historically covered the land of Egypt; it has not done so since the construction of the High Dam at Aswan.
