Ides!

Ides traditionally is the 15th of our MMJO months, all others are the 13th. Remember there is one market week between the Nones and Ides and from the Ides to the end of the month there were exactly 2 market weeks. "March, May, July, October, These are they, Make nones the seventh, Ides the fifteenth day." So now we know how to number the months based off of the Roman calendar and how it relates to March. I know, this has been more straight-laced and informative than usual but interesting for me.
