Description
Description:
Add the ability to define and display intercalary days (days that are not assigned to any day of the week) within a calendar.
These days should:
Appear at a fixed position in the calendar (e.g., between two specific weeks, at the end of a month, or mid-year).
Not increment the weekday counter (e.g., if the day before is a “Saturday,” the day after should be “Sunday,” with the intercalary day in between).
Support custom naming (e.g., “Mid-Fortnight Festival,” “Lithe,” etc.).
Optionally allow event scheduling on them.
Example Use Case:
In the Hyperborean (FGG - The Lost Lands) calendar, each fortnight is 15 days long: two 7-day weeks separated by a non-weekday festival day. That festival day is not part of any week and should be represented distinctly in the calendar UI without shifting the weekday cycle.
