Story of 9/11

September 11 is the 254th day of the year (255th in leap years) in the Gregorian calendar. There are 111 days remaining until the end of the year.

It is usually the first day of the Coptic calendar and Ethiopian calendar (in the period AD 1900 to AD 2099).

The terms September 11th, 11th September, 11 September, and 9/11 (pronounced "Nine-eleven") have been widely used in the Western media as a shorthand for the September 11, 2001 attacks on the World Trade Center and The Pentagon in the United States of America.

In other places of the world the media also use it as shorthand for other events; for example, the September 11, 1973 Coup d'État in Chile is referred to as "El 11 de Septiembre" or "El once" ("September 11" or "The eleventh" in Spanish) as shorthand for the Coup events; September 11 is also Enkutatash or New Year's Day in the Ethiopian calendar.
