Paopi (Coptic: Ⲡⲁⲱⲡⲉ, Paōpe), also known as Phaophi (Greek: Φαωφί, Phaōphí) and Babah (Arabic: بابه, Baba), is the second month of the Egyptian and Coptic calendars. It lasts between 11 October and 9 November of the Gregorian calendar, unless the previous Coptic year was a leap year. The month of Paopi is the second month of the Season of Akhet (Inundation) in Ancient Egypt, when the Nile floods inundated the land. (They have not done so since the construction of the High Dam at Aswan.)
Name
