Ancient Everyday – The Days and the Weeks in Ancient Rome

Salve readers!

We’re back in the Roman world for the third part in this mini Ancient Everyday blog series about, you guessed it: Time.

In the last two posts, we looked at how Romans tracked the years, as well as the evolution of the calendar in ancient Rome.

Today, we’re going to take a brief look at the Roman days and weeks which, in addition to many things, are one of their legacies to us.

The Roman days of the month were not numbered serially as they are today. They were numbered in relation to three specifically named days. It was from these three specific days that the other dates were counted retrospectively.

So, what were these special days, you might ask? They were the:


(the Kalends – first day of the month, and origin of our word ‘calendar’)


(the Nones – the ninth day before the Ides, or the fifth day of the month; seventh in a 31-day month; originally, the Nonae corresponded with the first quarter moon of the lunar month)



(the Ides – the thirteenth day; or the fifteenth day in a 31-day month; the Ides originally corresponded with the full moon of the lunar month)

The Ides of March – the date of Caesar’s assassination

So, those are the ‘special’ days in the Roman month. But how did they count the rest?

This is where it gets complicated…

The day was numbered or named by its place so many days before (ante diem) the Kalends, the Nones, or the Ides of the month.

But! The day immediately before one of the three named days was called pridie.

If you ever try to read Roman dates, you will also notice that they are always abbreviated.

In ancient Rome, the official Calendar was drawn up by the pontiffs (priests) who ensured the inclusion of the dates for religious festivals – and in ancient Rome, there were many of those! These festivals would be indicated by a letter or abbreviation representing a particular celebration beside the date.

So, those are the days of the Roman calendar, but what of the weeks? Did they have the exact same weekdays that we do? Or rather, do we have the same ones as the Romans?

Not exactly.

A Roman market day

Early on, the Roman week was eight days long. The eighth day was a market day, or nundinae.

The market day was a day of rest from agricultural labour, a time to take the produce or livestock to market.

To confuse things a little more, the period of time between market days was known as a nundinum.

The eight-day week did not last however.

The seven day period that we are familiar with was used at first in the East, especially by Hellenistic astrologers.

In Rome, the earliest reference to a seven day week is supposedly from the time of Augustus (27 B.C. – A.D. 14). This was eventually officially adopted by Emperor Constantine in A.D. 321.

Finally, what were the names of the days of the week in ancient Rome?

Well, they were named after the gods and planets, and to this day the names used in the various Romance Languages preserve the Roman tradition. Beginning with Monday, they are:

Dies Lunae (the day of the Moon)

Dies Martis (the day of Mars)

Dies Mercurii (the day of Mercury)

Dies Jovis (the day of Jupiter)

Dies Veneris (the day of Venus)

Dies Saturni (the day of Saturn)

Dies Solis (the day of the Sun)

There you have it, the Roman days and weeks!

The legacy of the Romans never ceases to amaze me.

Next week is the fourth and final part of this Ancient Everyday blog series in which we will be looking at how the Romans told the time of day.

Until then, thank you for reading!


The World of Children of Apollo – Part III – The Severans

Imperial Family - The Severans

Imperial Family – The Severans

The Severans were a very interesting family and not without their tales of violence and greed and uniqueness of character. The period is not marked by something so brutal as the psychotic reign of Caligula, but there are certainly many more dimensions. It is a time of militarism, of a weakened Senate, a time of spymasters in various camps. It is a time marked by the rise of lower classes, the presence of powerful women and, over it all, a blanket of religious superstition at the highest levels. Many believe that it is this period in Rome’s history that marks the true beginning of the end of the Roman Empire.

The emperor at the time that Children of Apollo takes place is Septimius Severus (A.D. 193-211). He was the son of an Equestrian from Leptis Magna in North Africa. When Commodus was killed in A.D. 192, Severus was governor of Pannonia. When the Praetorians decided to auction the imperial seat a short time later, Severus’ legions declared him Emperor. He subsequently defeated his two opponents who had also declared themselves Emperor: Clodius Albinus and Pescennius Niger. A purge of his opponents’ followers in the Senate and Rome made Severus sole ruler of the largest empire in the world.

Septimius Severus

Septimius Severus

Septimius Severus was a martial emperor, the army was his power and he knew how to use it, how to keep the legions loyal and happy. He increased troops’ pay and in a radical move, allowed soldiers to get married. Severus was good to his troops, his Pannonian Legions and victorious Parthian veterans. He promoted equestrians to ranks previously reserved for aristocrats and lower ranks to equestrian status. There was a lot of mobility within the rank system at the time due to Severus ‘democratization’ of the army. Remember, this was an emperor who favoured his troops, especially those who distinguished themselves. The Emperor is open and friendly with Lucius Metellus Anguis in Children of Apollo, but there are prices to be paid. No favour is free.

Julia Domna

Julia Domna

One of the most interesting characters of the period is Severus’ Empress, Julia Domna. She appears as one of the strongest women in Rome’s history, an equal partner in power with her husband who heeded her advice but also respected her. Julia Domna was the first of the so-called ‘Syrian women’, she and her sisters hailing from Antioch where their father had been the respected high priest of Baal at Emesa (Homs in modern Syria).

Julia Domna was also highly intelligent, known as a philosopher, and had a group of leading scholars and rhetoricians about her. They came from around the Empire to be a part of her circle, to win commissions from her. No doubt, her strength also bought her a great many enemies, including the Praetorian Prefect and kinsman to Severus, Gaius Fulvius Plautianus. The conflict between the Empress and the Prefect of the Guard is something that will cause Lucius Metellus Anguis a good deal of trouble in Children of Apollo and sequel, Killing the Hydra. To boot, Plautianus’ daughter, Plautilla, was married to the Empress’ son, Caracalla. One can imagine what family gatherings must have been like!

Apart from the power, their keen ability to wield it, and their nurturing of the army’s loyalty, a very interesting and important aspect of Septimius Severus and Julia Domna is the great faith they both placed in astrology and horoscopes. They consulted with their astrologer and the stars on all decisions. Astrology affected everything, including Severus’ choice of her as his wife – he was greatly impressed by her horoscope.

By all accounts Caracalla and Geta, Severus’ heirs, were both at odds much of the time. The two brothers seem to have tolerated each other’s presence and competed fiercely, even in the hippodrome where at one point they raced each other so fiercely on their chariots that they ended up with several broken bones, almost leaving their father without a successor. Caracalla seems to have been the favourite of the Empress, though in later years Julia Domna does come to Geta’s defence, however much in vain.

Julia Maesa

Julia Maesa

The Syrian women continued to hold power under the daughters of Julia Domna’s older sister, Julia Maesa who, herself, managed to save the dynasty for a time after the death of Caracalla. Julia Maesa was the mother of Julia Soaemias and Julia Mamaea, both mothers in their turn, of the last Severan emperors, Elagabalus and Alexander Severus. These powerful women held the family together. However, in the end, under Alexander Severus, the loyalty of the army was lost, and what once gave the Severans their ultimate power became their downfall.

There is a lot more to each of the people I have mentioned so briefly here and it is a part of Roman history that is not often explored. However, the Severans made their mark on the Empire and brought about massive changes, from artwork, to marriage for legionaries, to a crippling of the Senate and the extension of Roman citizenship to people all over the Roman Empire. They were strong, religious, varied and flawed, and all make for fantastic fiction!



In the next instalment of The World of Children of Apollo, we’ll be following Lucius Metellus Anguis to Ostia and Rome itself as he leaves North Africa to return home after many years. If you are up for a Roman holiday, be sure to check it out!
