Roman Months Posted by Brittany Britanniae on Sep 23, 2019 in Latin Language, Roman culture
Recently, I was having a conversation with my husband about the months of the year and the days of the week. While the days of week are more Germanic in nature (for English at least), the months of the year have a very interesting history. So, let’s dive in.
The Roman calendar used a system of months, and special days in each month. Some calendars were carved in marble or stone, but many were painted on walls for decoration.
In 45 B.C.E., Romans modified their method of marking time to keep it in phase with season. Eventually, they accomplished the Julian Calendar. Month lengths were extended to bring the calendar’s total to 365 days, making it truly solar. This change was accompanied by addition of an extra day every fourth year (after February 23rd) because of the almost six extra hours beyond 365 days in a tropical year.
Much of the knowledge we now have about early Roman calendars came from Ovid’s Fasti, a Roman born in 43 B.C.E., and from Plutarch, a Greek biographer who wrote between C.E. 105 and 115.
Initially, it contained only ten months. It has been suggested that those month lengths reflected growth cycles of crops and cattle. When compared with the solar year, it had an uncounted winter period of approximately sixty days.

As you can see from the chart above, that many of the months we will still use today are from Ancient Rome.
January — Janus’s month
ETYMOLOGY: Middle English Januarie
Latin Januarius “of Janus”
Latin Janu(s) “Janus” + –arius “ary (pertaining to)”
Latin Januarius mensis “month of Janus”
BACKGROUND: Janus is the Roman god of gates and doorways, depicted with two faces looking in opposite directions. His festival month is January. Januarius had 29 days, until Julius when it became 31 days long. There was also disagreement in Ovid’s day as to the sequence and time at which Januarius ( and Februarius) were added to the original ten months. Januarius became part of the calendar within half a century after Rome was founded because Plutarch said that Numa, the king who followed Romulus, made it the first month of the year and made February the last.
February — month of Februa
ETYMOLOGY: Middle English Februarius
Latin Februarius “of Februa”
Latin Februa(s) “Februa” + –arius “ary (pertaining to)”
Latin Februarius mensis “month of Februa”
Latin dies februatus “day of purification”
BACKGROUND: Februarius had 28 days, until circa 450 BC when it had 23 or 24 days on some of every second year, until Julius when it had 29 days on every fourth year and 28 days otherwise. Also, adding five days at year-end (to extend February’s length to 28) is similar to the change made by many other peoples who, around the time of Rome’s founding, added five days to their own calendar, but considered them to be unlucky and not part of the normal year.Februa is the Roman festival of purification, held on February fifteenth. It is possibly of Sabine origin.
March — Mars’ month

Old English Martius
Latin Martius “of Mars”
