Why Does the Year Start on January 1? (Encore)

Roman Calendar

The Roman calendar initially consisted of ten months, with the year starting in March. Gary Arndt explains that the months were named after their numbers, such as Quintilius and Sextilius, but this system left two months unaccounted for. To address this, King Numa added January and February, shifting the year's start to January 1, possibly due to the consuls' terms or its proximity to the winter solstice 1.

The Romans set January as the first day of the year Julius Caesar sets the Julian calendar. And we get to where we are today.

However, the calendar system fell apart in the Middle Ages, leading to various New Year dates across Europe until the Gregorian reforms standardized January 1 again.

   

Gregorian Reforms

Pope Gregory XIII addressed the Julian calendar's inaccuracies by introducing the Gregorian calendar, reinstating January 1 as New Year's Day. Gary Arndt notes that this change was initially resisted by Protestant and Orthodox countries, with England adopting it only in 1752 2.

The very first thing mentioned in the act was the problem with using March 25 as the new year, when almost everyone else in Europe used January 1.

Despite the widespread adoption of the Gregorian calendar, various cultures continue to celebrate their traditional New Year on different dates, highlighting the diversity in how we mark the passage of time.
