October (Roman month) did not number days of a month sequentially from the 1st through the last day. Instead, they counted back from the three fixed points of the month: the Nones (5th or 7th), the Ides (13th or 15th), and the Kalends (1st) of the following month. The Nones of October was the 7th, and the Ides was the 15th. The last day of October was the "pridie Kalendas Novembris," "day before the Kalends of November". Roman counting was inclusive; October 9 was "ante diem VII Idūs Octobris", "the 7th day before the Ides of October," usually abbreviated "a.d. VII Id. Oct."

In the "Laus omnium mensium" ("Praise of All the Months"), a poem dating to the early 6th century, September "divides the hours equally for Libra". In an ancient Christian mosaic from Gerasa in the province of Arabia (present-day Jordan), September has the typical attributes of a vintager in Roman art—a young man wearing a tunic and chlamys carries a bunch of grapes in his right hand and has a basket on his shoulder—but is labeled as "Gorpiaios", the first month of the year in the local calendar, equivalent
