What are the Ides, you wonder?
The Roman calendar consisted of 3 reference days:
1. Kalends marked the New Moon and the first day of the month.
2. Nones was the first quarter moon and the 7th day if the month had 31 days in it. Otherwise it was the 5th.
3. Ides was the Full Moon and the 15th day if the month had 31 days in it. Otherwise it was the 13th.
All other days were described by how many days until Kalends, Nones, or Ides.
They had a 10 month lunar calendar starting on March 1. January and February did not exist as they didn't count the 61 days of winter as nothing grew during that time. The Ides of March was a time of celebrating the New Year and the start of the growing season for this agrarian society.
In no small part, Shakespeare's play "Julius Caesar" has brought March 15 to mean a something bad is going to happen. Several TV episodes and even a movie have been based The Ides of March. This year, Groundspeak has given The Ides of March as the deadline for the Pi Day souvenirs. Not saying that's a bad thing, just that I found it humorous.
This is a little meetup under the shelter in Hillendale Park to talk about anything cache related, including how many of the Pi Day souvenirs you plan to get from two days before the Ides until the Ides of March.
