Custom Calendars

This is probably a rather unique/special need but I use Capacities primarily to organize my creative writing and it's amazing (and much better than most specialized applications) for creating and connecting character sheets, locations, chapters, notes, alternative versions etc. One thing I'm really missing is the option to create a custom calendar system for fictional worlds.

This is probably smth that would be hard to impossible to implement given how the current calendar is used and integrated but since Writing is explicitly addressed as a use case for Capacities I thought it might be interesting to consider adding this in the long run.
