The calendar has been updated, it now does not use FullCalendar. In my mind, FullCalendar is great and worked out of the box without modding it.... but it was overkill for what this project needed.
Pulling in the crypto data has been moved back to using jQuery and away from React Fetch. I was getting odd errors.... and until I get to understand React a little better, I felt it was best to use what worked all the time.
