The Thirteenth Month Solution

The radical proposition of a 13-month calendar isn't just some random thought experiment—it's actually the International Fixed Calendar, proposed by Moses Cotsworth in the early 1900s. Each month would have exactly 28 days (4 perfect weeks), with the 365th day being a special "Year Day" belonging to no month or week. Leap years? Just add another special day.

The lunar cycle is approximately 29.5 days, so we'd be closer to lunar alignment but still off. The real kicker? Companies actually tried this. Kodak used this calendar internally from 1928 to 1989. Sixty-one years of 13 months called things like "Sol" and "Liberty."

Would it work? Sure. Would humans collectively agree to change something as fundamental as our calendar? We can't even agree on whether pineapple belongs on pizza.
