Popularity Over Time
Ides draws upon the Latin “Īdūs” and the old French “Ides,” but the word is also related to the Etruscan “iduāre,” meaning “to divide.”
Did you Know?
In ancient Roman times, "ides" referred to a month's first new moon, which placed the ides between the 13th and 15th day of the month. The term has always been closely associated with “the ides of March,” mentioned in Shakespeare’s history play “Julius Caesar,” but there are ides in every month. Formally, the ides are 15th day of March, May, July, and October, and the 13th of the other months.
