The Rational Almanac

The Rational Almanac is not really an almanac but a history of the form, from early Egyptian almanacs to modern-day. Moses Cotsworth builds on that history and proposes that in the future, holidays are fixed on particular dates to make almanacs reusable.  He also recommends that some holidays be moved to different days or months more suitable for their celebration. He reasons that since everyone spends their time outside on Easter, we should move the holiday to May, when the weather is more agreeable. He also recommends adding a 13^th month in midsummer – who would not want more summer months?
