Is there an example out there somewhere of how to render every possible input / output of the calendar?

Here's an example of an event with start date, end date, monthly recurrence until xx date on the first monday of every month.

I'm thinking I'll have to do a switch for every possible day / date option like 1 = monday, 2 = tuesday, etc. but wondering if anyone has found a better option.

{
"recurrence": "4",
"weekInterval": "1",
"monthYearOption": "2",
"interval": "1",
"weekDay": "1",
"month": "1",
"monthOption": "1",
"startDate": "2019-06-03 09:00",
"endDate": "2019-06-03 10:00",
"days": [],
"months": [],
"exceptDates": [],
"recurUntil": "2019-12-02"

}
