Roman Emperor Augustus and Caesar each had their own names for the month. Roman citizens and the Senate asked the then Roman Emperor Tiberius to name November. But Tiberius did not agree, and he wisely told everyone that if each Roman emperor named his month, what would happen to the thirteenth emperor? So, November still retains the old name Novem, That is, the Latin "9" means that this month in the old calendar turned out to be the ninth month. English November evolved from this. It is also called winter moon, frost moon and frost moon.
