September, the ninth month of the Gregorian calendar.
During Ramadan, the ninth month of the year, that's around September on our calendar (Gregorian).
November used to be the ninth month of the year (and logically should be), until countries changed from the Julian Calendar to the Gregorian Calendar. For instance, England did not change to the Gregorian Calendar until 1752.09.14. The states of Washington, Oregon, and those on the Eastern Seaboard, changed on this date, as well. The rest of the United States of America changed in 1582.November Latin: November. From the word novem, nine, because it was the 9th month in the old Roman calendar. http://www.tondering.dk/claus/calendar.html = The Calendar FAQhttp://www.norbyhus.dk/calendar.html = The Perpetual Calendar (dates for when most countries switched to using the Gregorian Calendar)http://sacred-texts.com/time/smd/smd13.htm = The Romans and the 9th MonthOf course, for general knowledge, you can search "Julian calendar" and "Gregorian calendar" on Wikipedia.org.
