Now, before I bringout my first guest, I just want to say that February is Black History Month. Isn't that nice? The Man gives us February because it's the shortest month of the year! Now, I'm not complaining, but I think we deserve at least a thirty-day month. It's also the coldest month of the year, just in case we wanted to have a parade.
The hobbit calendar from Lord of the Rings had 5 (or 6, in leap years) days that weren't part of any month in order to make the whole thing work out perfectly. That allowed every month to have exactly 30 days, and any given date would have the same associated day of the week every year. No need to change calendars every year.
Also, the elven calendar added 3 leap days every 12 years instead of 1 every 4 years. That seems kind of interesting.
I wonder if people will still use current Roman calendar in the year 2100...
We should change our calendar to 46 weeks, all weeks = 8 days except for the last. The last week is 5 days, where the leap day is added. There would be 10 months.
