History of New Year’s Day: Why on January 1?


We have the ancient Romans to thank for celebrating New Year’s Day on January 1. It wasn’t always that way. Previous civilizations celebrated it in March to observe the “new year” of growth and fertility.

Before calendars existed, the time between seed sowing and harvesting was considered a cycle or a year. But the Romans moved the date of New Year to January 1, as I’ll explain below, but first a little on calendars.

The word Calendar comes from the first day of a month in the Roman (Latin) calendar: kalendae.



A variety of calendars were developed for all kinds of purposes:

  • Religious: “holy days” or holidays. Some can be regional and historical: Christian, Chinese, Jewish, and Islamic.
  • Astronomical: connecting the movement of celestial objects in the sky. There may be lunar (Jewish), solar (Julian), or even lunisolar calendars (Gregorian.)
  • Commercial: tracking trade and billing.
  • Arithmetic: for calculating differences between dates. Because there was no Year 0, the difference between 1 BC and AD 1 is one year, not two years. Which is a challenge for Astronomical Calendars

JanuaryCalendars often track the movement of the sun, moon, or both. Like the Egyptians of antiquity, some traced the movements of planets such as Venus.

Setting the date for the universal observance of Easter has caused international controversy – until resolved at the Council of Nicaea in AD 325 – and occasioned several calendar reforms. Emperor Constantine wanted Easter observed on the same day across the Roman Empire and not be tied to the Jewish calendar.

If you don’t account for Easter, there are only 14 different permutations of the de facto international standard Gregorian Calendar (named after Pope Gregory XIII, who established it in 1582) now commonly in use. But because the date for Easter Sunday can vary so much – it’s the first Sunday after the first Paschal Full Moon after the Vernal Equinox, and let’s not forget Leap Year – there are 70 different calendars.


Date of New Year’s Day

So, back to the date for New Year. Originally, it was celebrated late in March when Spring began with the Vernal Equinox. The ancient Babylonians were the first recorded observers of New Year festivities some 4,000 years ago. They marked it with the priests offering sacrifices at their temple, kind of like their church.

These celebrations lasted 11 days due to the numerous state-sponsored football bowl games played then. But because there were also the priestly religious observances held at this time, it caused a cry from the populace for the “separation of church and state-championships.”


Roman New Year

New YearThe Romans also celebrated the New Year in March. Still, there were so many adjustments to their calendar by their rulers, in part – this may be hard to believe – to extend their terms of office that calendar dates no longer were synchronized with any astronomical movements. The Roman Senate was forced in 153 BC to start the new year on January 1.

This did not sufficiently discourage calendar tampering, and in 46 BC, Julius Caesar allowed the year to extend to 445 days, the “Year of Confusion,” until his new calendar reformed matters. It was called, ironically, the Julian Calendar.

This calendar continued to be used for over 1600 years in Europe and European colonies and is still used by the Eastern Orthodox Church. Generally, a Julian date can be calculated as thirteen days earlier than (behind) the Gregorian Calendar date. (See my explanation here.)


Christianity’s Influence on New Year’s Day

Circumcision of Christ

When Christianity became the Roman Empire’s official religion in the 4th century, some Emperors continued holding riotous New Year’s celebrations, like our “toga parties” but more authentic.

In part to counter this activity, the Church established a holy day on January 1, the Feast of the Circumcision of Christ, also known as the Feast of the Holy Name of Jesus, when the name Jesus would have been conferred upon his circumcision. Catholics, Lutherans, Episcopalians, and some Eastern Orthodox sects have still observed it through the centuries.

The jury is still out on whether this has quieted New Year’s celebrations.
