Since you've dropped the lunar aspects, you can just intercalate a whole week at a time instead of having an orphan day every year, although this would cause the equinoxes and solstices to drift.

Your proposal seems to be: https://en.wikipedia.org/wiki/International_Fixed_Calendar

I independently derived it, and chose a different location and name for the new month, but it’s fundamentally identical to the IFC, yes. I chose the name Leftober because it’s made from the leftover 2 or 3 days from the other months. Also, from the article:

Every year has 4 equal-length quarters of 91 days, each 13 weeks or 3+1⁄4 months long.

13 is my favorite prime number and 91 my favorite nonprime. It’s 7x13, a semiprime, and the only composite below 100 which can’t be factored by tricks and must be memorized:

  • Multiples of 2 and 5 end in 0,2,4,6,8 and 0,5 respectively
  • Multiples of 3 and 9 have their digits sum to 3,6,9 and 9 respectively
  • 49 is the square of 7 and is typically memorized in the square sequence 0,1,4,9,16,25,36,49,64,81,100,121,144
