One of the ongoing struggles of the Roman polytheistic life is trying to figure out when the year begins. The original Roman year began in March, or Martius, the opening of the “war” season. The original calendar was also lunar, which means that kalends falls on the new moon and ides on the full moon. So the first of your year could be March 8th, or January 9th, or January 1st, since our current calendar is based on the Roman one.
None of this helps you figure out what Roman year it is, since that’s figured “after the founding of the city of Rome, inconveniently marked as April 21st, 753 B.C. E. That makes it 2768, for now.
May Janus, god of good beginnings, bless you and your household in this New Year. Whenever it starts for you!
