Iran, Teheran - Nayrouz (The New Year Festival) - an event which was Coptic and originated in Egypt. Ignorant of the Egyptian language for the most part, Arabs confused the Egyptian new year's celebrations (called the feast of Ni-Yarouou - the feast the rivers), with the Persian feast of Nowruz. The misnomer remains today, and the celebrations of the Egyptian new year on the first day of the month of Thout are known as the Neyrouz.
