Is There a Plugin to Attach to a Calendar?

Fantasy calendars are built for D and D people, but you can just use it as a normal calendar. Because it's D and D, you can literally make anything so you could instead of weeks, it could be something else like rename how many weeks there are in the year. You've got moon settings and there's so much stuff in there. That plugin will take you a while to play with because there are soYou literally create the calendar. But you can't if you want to use them for a real life use case - then you need to connect the plugin with the thing you want it to do. It just isn't around at the moment.
