Leap year
After Caesar's assassination, Mark Antony had Caesar's birth month Quintilis renamed July (') in his honor. After Antony's defeat at Actium, Augustus assumed control of Rome and, finding the priests had (owing to their inclusive counting) been intercalating every third year instead of every fourth, suspended the addition of leap days to the calendar for one or two decades until its proper position had been restored. See Julian calendar: Leap year error. In 8BC, the plebiscite "Lex Pacuvia de Mense Augusto" renamed Sextilis August (') in his honor.
