Roman republican calendar

By Konstantin Bikos and Vigdis Hocken. The Roman calendar is the ancestor of our modern calendar. Some of its features are still in use today. The Roman calendar is the time reckoning system used in ancient Rome. However, because the calendar was reformed and adjusted countless times over the centuries, the term essentially denotes a series of evolving calendar systems, whose structures are partly unknown and vary quite a bit.

Attributed to Romulus himself, the Roman calendar originally was determined by the cycles of the moon and the seasons of the agricultural year. Beginning in March in the spring and ending in December with the autumn planting, the year then was ten months long and had six months of thirty days and four of thirty-one, for a total of days ten lunar months actually comprise about days.

Since each month began and ended with the new moon, that day would have belonged both to the new month and the old and must have been counted twice. The remnants of this early calendar still can be recognized in the numbered names for Quinctilis July , Sextilis August , September, October, November, and December. The two months of winter, when there was no work in the fields, were not counted; Cato, for example, speaks of payment for olives being due in ten months De Agricultura , CXLVI.

Christmas is celebrated to remember the birth of Jesus Christ , who Christians believe is the Son of God. The name ‘Christmas’ comes from the Mass of Christ or Jesus. A Mass service which is sometimes called Communion or Eucharist is where Christians remember that Jesus died for us and then came back to life. The ‘Christ-Mass’ service was the only one that was allowed to take place after sunset and before sunrise the next day , so people had it at Midnight!

The dating system presently adopted in most countries of the world, as well as many names too, such as those of months and weekdays, are largely based on the ones that were already in use well over years ago; the same word “calendar” comes from Kalendae , indicating the first day of each month. Some details of this system, though, would now appear very complicated and unpractical. This page describes how the archaic systems developed into the present one, and its many connections with the city of Rome.

This scheme, likely of Greek origin, was already in use by the time of Rome’s foundation, but it was obviously inaccurate; for this reason, an uncounted number of days was likely added, so that events for which a specific timing was required, such as sowing or gathering the harvest, could be carried out reasonably on time. This year originally started with the month of March New Year’s Day fell on March 14 , probably because early spring is the period in which nature comes to new life again after the cold season.

But this change did not last long: when the Etruscan dynasty he belonged to was dismissed about one century later, March became again the first month, according to Latin tradition. The day system, though, kept causing a certain mismatch between different years, due to its short duration, and the problem was coped with by adopting a thirteenth month, named Intercalans “intercalary month” or Mercedonius “month of wages”, because by this time of the year workers received their payment ; its length was either 27 or 28 days.

About once every two years, the additional month was inserted between February 23rd and 24th, and the five remaining days of the month were cancelled. The pontefices , a body of officers who presided over religious celebrations, decided when the Intercalans had to be adopted, and how long it would have lasted. Their head was the pontifex maximus , a charge held by the emperor himself up to the early Christian age.

Numa Pompilius , according to tradition the second king of Rome ?

To obtain sufficient days for his new months, he is then said to have deducted one day from the day months, thus having 56 days to divide between January and February. But since the Romans had, or had developed, a superstitious dread of even numbers, January was given an extra day; February was still left with an even number of days, but as that month was given over to the infernal gods, this was considered appropriate.

The system allowed the year of 12 months to have days, an uneven number.
