So here’s what I’ve figured out. The calendar will only allow you navigate to months that have events. So even though you start the calendar “Today” if you don’t have events until two months later, once you navigate there, you can not return to “Today” unless you refresh the page.
Yes, you can override the color of the disabled class, but that does not allow you to navigate.
I don’t believe this is a great user experience, so I’m wondering if I need to add some kind of explanation for why the arrows disappear. Has anyone else done something like this? It’s a bummer that we would even need to do this.
