Is it possible that the discrepancy is due the difference between the Julian and Gregorian calendars?

[Verginius Rufus]

No--this was almost 300 years before the Gregorian calendar was introduced, and the discrepancy between the Julian calendar and what the date should have been (assuming the calendar had been as accurate from A.D. 325 as it was after A.D. 1582) would have been about 8 days, not 6.

If they were counting days in the Roman fashion, the first day of November would be the Kalends of November and the 7th day of November would be the 7th day before the Ides of November.
