I’m getting a little tired of the Gregorian calendar and while I have considered the alternatives, I think Joli is onto something. First, Joli Q. is a world-class game author. He has created several dozen games over the past 30-plus years. He also invented a calendar called the Intercalian Perpetual Calendar. It is notable because it introduces a four day work week with a twist - there are only 6 days in each week. And let’s not forget Intercalia - a yearly festival week filled with games, beer, and general laziness. I like it!

Created by games inventor and teacher Joli Quentin Kansil, the Intercalian Perpetual Calendar is designed for practicality in that each month begins on Sunday and ends on Saturday. Thus, any date in any month always falls on the same day. For example, the 23rd of February ? or March or November ? always falls on Friday. Likewise, each year begins on Sunday and ends on Saturday so the calendar is perpetual in that it never needs to be replaced from year to year.

Each of the 12 months is divided into five weeks of six days. There is no natural reason why it is necessary to have seven days in a week! No Wednesday is included in this calendar, but in that there are more weeks in the year, the work week is still the same number of hours, and the school year is just as many days.

In addition to having only six days in a week, the other major change is the introduction of an extra week ? called Intercalia ? at the end of the half-year. It is designed to be a week of relaxation, festivities, etc., and each year there could be a world-wide theme attached to it. So as to conform to the exact length of a year, Intercalia does not occur every eighth year, and it is also eliminated one extra time every 800 years.
