1. January 1st was not considered a new year until recently. Most medievals celebrated New Year’s in mid-March, when melting snow followed by sprouting greenery signaled the awakening of new life.
2. The first medievals to celebrate the New Year on January 1st were the Romans in 153 B.C. January, as a month, did not even exist until Julius Caesar created a new calendar based on the sun instead of the moon.
In order to synchronize the calendar with the sun, he extended the year to 355 days. It was this new ‘Julian’ calendar that included the months of January and February, and heralded the celebration of the New Year in January.
