The Romans later renamed months after Julius Caesar and Augustus, renaming Quintilis as "Iulius" (July) in 44 BC and Sextilis as "Augustus" (August) in 8 BC. Quintilis was renamed to honour Caesar because it was the month of his birth. According to a senatus consultum quoted by Macrobius, Sextilis was renamed to honour Augustus because several of the most significant events in his rise to power, culminating in the fall of Alexandria, occurred in that month.

Other months were renamed by other emperors, but apparently none of the later changes survived their deaths. In AD 37, Caligula renamed September as "Germanicus" after his father; in AD 65, Nero renamed April as "Neroneus", May as "Claudius" and June as "Germanicus"; and in AD 84 Domitian renamed September as "Germanicus" and October as "Domitianus". Commodus was unique in renaming all twelve months after his own adopted names (January to December): "Amazonius", "Invictus", "Felix", "Pius", "Lucius", "Aelius", "Aurelius", "Commodus", "Augustus", "Herculeus", "Romanus", and "Exsuperatorius". The emperor Tacitus is said to have ordered that September, the month of his birth and accession, be renamed after him, but the story is doubtful since he did not become emperor before November 275. Similar honorific month names were implemented in many of the provincial calendars that were aligned to the Julian calendar.

Other name changes were proposed but were never implemented. Tiberius rejected a senatorial proposal to rename September as "Tiberius" and October as "Livius", after his mother Livia. Antoninus Pius rejected a senatorial decree renaming September as "Antoninus" and November as "Faustina", after his empress.
