Add leap year exceptions so we can have a proper Gregorian calendar

Feature Upgrade · Calendars · Created by Fociño

calendar chronicles leap Gregorian leap-year Julian

What functionality is missing? What is unsatisfying with the current situation?

  Currently, even if calendars in the Chronicles feature do permit setting up leap years, there are no exceptions in regards of skipping years that are evenly divisible by certain numbers (which is how the Gregorian calendar actually works, as well as the Revised Julian).   We are only capable to have the basic original Julian Calendar, where leap years happen every 4 years and that's it, without exceptions.  

How does this feature request address the current situation?

  Adding a new field of "except evenly divisible by" or similar, to avoid such year from being a leap year, would fix the inability to have a Gregorian Calendar in World Anvil.   But if you wanted to take it further, maybe some sort of equation field, or some extra exception options (evenly divisible, having remainders of X when divided by Y...) would make World Anvil able to have a Revised Julian Calendar ("in the Revised Julian version, years evenly divisible by 100 are not leap years, except that years with remainders of 200 or 600 when divided by 900 remain leap years, e.g. 2000 and 2400 as in the Gregorian calendar") or any other complex calendar like lots of players seem to want to be able to do yet they can't.  

What are other uses for this feature request?

  It could eventually make its way to the Timelines feature too, whose calendars can't even add leap years yet. World Anvil has a lot of potential for complex worldbuilding yet it lacks some basics in this area, and many players are waiting hopefully.

It is not true that this has been suggested before, as far as I understand. In https://www.worldanvil.com/community/voting/suggestion/a17dd49b-5aca-4e16-befd-72ab2271e46a/view it was suggested to simply add leap years ("Make it possible to add leap days that occur every x years" is equal to adding simple leap years). It is not the same I'm asking, please, reread my suggestion.

    While complicated to build, these do allow for a system that fits more to both reality and our own creations.
