Misty Mere Calendar

by Dag Ole Nordhaug

The Misty Mere Calendar is a variation of the Thirteen Month Leap-Month Calendar.

A year is usually made of 364 days or thirteen moonats (a mashup of "Moon" and the German word for month, "Monat").

Every moonat has 28 days or four weeks.

Moonats

Moonat names

After 293 moonats, an extra intercalary moonat called Ygdrasil is inserted and the year has fourteen moonats (392 days). The interval between long years is approximately 22.53 year.

Leap Cycle

The Misty Mere calendar leap cycle is 541 years which is 45 years less than two leap cycles in the original calendar.

On the last year of the cycle Ygdrasil occurs just before the last moonat.

The average year length is:

${\frac {(541\times 13+24)\times 28}{541}}=365.242144{\text{ day}}$

The epoch of the calendar is Monday, 15 January 0001 in the Proleptic Gregorian calendar (two weeks later than the original). Every year and every moonat in the Misty Mere calendar begins on a Monday.

Year 2029 is long with an intercalary moonat inserted between At-Wyrd and At-Vi'ansa.
