Pax Calendar
Pretty unpleasant to have an extra week once in a while, IMO. Seems this calendar would lead to confusing seasonal drift in more stable (pre-industrial) climate, but I guess there&#x27;s no seasonal predictability going forward .<p>As a fun thought experiment, I once devised my own Equal Terrestrial Calendar, intended to be both predictable and <i>actually</i> secular.<p>- Weeks are 5 days long.<p>- Months are 6 weeks long (exactly).<p>- Thus, a month is 30 days, and as close as possible to an average lunar month.<p>- Every week&#x2F;month&#x2F;year begins on the same day of the week<p>- Work weeks are 3 days long.<p>- 3 intercalary holidays at the winter solstice, and 2 intercalary holidays at the summer solstice (make it 3 every leap year)<p>- 30 days&#x2F;month * 12 months + 5.25 days (intercalary) = 365.25, but in a fairly even spread<p>Not possible for a calendar to be perfect, but I&#x27;d really enjoy living in this world.
