A year shaped by religion
For the Romans, the calendar was not just a way to count days. It sorted them into those on which public business and legal action were permitted and those set aside for the gods. Days were marked in a published list called the fasti, and the pontiffs, the priests who looked after state religion, were responsible for much of its administration. In the late Republic the calendar fell out of step with the seasons, and Julius Caesar introduced a reformed solar calendar that took effect in 45 BCE and is the basis of the Julian calendar. Many festivals are much older than the reform, and their original meanings were already unclear to Roman writers such as Ovid, whose poem on the calendar, the Fasti, is a key source. It covers only the first six months of the year.
Because ancient evidence for individual festivals is often scattered and late, descriptions below are cautious. Dates are traditional, and details of ritual sometimes come from authors writing long after the customs began.
Some of the main festivals
The Roman festival calendar contained dozens of observances. A few of the better-known ones, with their usual dates, were:
- Lupercalia (15 February): a rite involving the Luperci, priests who ran around a part of the city. The exact meaning is debated, but it is associated with purification and fertility.
- Matronalia (1 March): a festival of married women, connected to the goddess Juno, in which husbands traditionally gave gifts. The role of Roman matrons in religious life made this a recognised women’s occasion.
- Cerealia (mid-April): honoured Ceres, goddess of grain, with games.
- Parilia (21 April): a pastoral rite of purification that was also taken as the traditional date of Rome’s founding.
- Vestalia (9 June): the festival of Vesta, goddess of the hearth, when the temple was opened to married women.
- Ludi Romani (September): a major set of public games in honour of Jupiter.
- Saturnalia (from 17 December): the midwinter festival discussed below.
Not all festivals involved the whole city. Some were observed by families, neighbourhoods or specific guilds. Public festivals could be funded by the state, and games, theatre shows and processions were a way of tying religion to entertainment. When people attended games, they were taking part in a religious occasion as well as a spectacle.
Working days and holidays
Roman days were broadly classified as fasti (days on which legal business could be conducted), nefasti (days on which it could not) and others for assemblies. This meant the calendar directly affected courts and magistrates, a link visible in the history of Roman civil law. Festival days often meant a pause in ordinary work, though how fully people stopped depended on their status. Enslaved workers and the poor were not always free to take a day off.
Saturnalia
Saturnalia honoured Saturn, an old god linked with agriculture and associated in Roman tradition with a mythical golden age. It began on 17 December and, according to the sources, grew from a single day to as many as seven by the imperial period, although official length is debated. A temple of Saturn stood in the Roman Forum, and the festival opened with a sacrifice there, followed by a public banquet. Crowds are described shouting “Io Saturnalia”.
Several customs are repeatedly mentioned by writers such as Seneca, Martial, Lucian and the later author Macrobius:
- Gift giving. Friends exchanged small presents, including candles and little clay figurines. Gifts were not meant to be extravagant, though some sources mention complaints about lavish ones.
- Relaxed dress. People set aside the formal toga and wore a casual outfit, and many wore a felt cap that was associated with freed slaves.
- Gambling and games. Dice were allowed for the occasion, even though gambling was normally restricted.
- A mock ruler. Some households appointed a “king” of the festival whose commands everyone followed in jest.
- Role reversal. Roman slavery was a harsh institution, but the holiday involved some temporary relaxation of normal hierarchies. Sources describe slaves being allowed to speak freely and, in some accounts, being served by their masters or dining with them. The degree to which this happened in practice is uncertain, and the festival did not end slavery or alter the social order.
The seasonal feel of Saturnalia, with feasting, lights and gift giving in midwinter, is one reason it is often compared with later winter celebrations. Scholars are cautious about drawing direct lines, since customs that look similar can have separate origins, and the connection with Christian holidays is complicated. The Romans also celebrated other late-December occasions, and later imperial cults added further festivals.
The Kalends of January and the new year
The new year in the Republic came to be counted from 1 January, when the consuls took up office. The Kalends of January was marked by public ceremonies and private gifts, and it followed hard on the heels of Saturnalia. Because of this, midwinter in Rome was a lengthy stretch of holiday atmosphere. The Roman Senate also held ceremonial sessions to mark the start of the magistrates’ year.
Festivals across the empire
As Rome grew, it absorbed cults from the Greek East and other provinces, and local communities added their own holidays. Cities across the empire marked imperial anniversaries and festivals of the emperor, a development that took off after the Augustan principate. The calendar therefore reflected both inherited tradition and political power. It also meant a Roman in Gaul, Egypt or Syria might share a handful of holidays with someone in Rome while keeping many local ones, which is a reminder that “the Roman calendar” in practice was a patchwork.
