Tell us what you are trying to do?
I am trying to filter dates in chronological order from newest to oldest but I am not sure how to do that.
My options are:
"Order by: Name, ID, Count, Slug, Group, None"
I was not sure if I had to create a taxonomy for these dates since I already have a sermon date option but it would show up as a calendar icon instead of a drop-down menu.
Is there any documentation that you are following?
No
Is there a similar example that we can see?
The dates on this page: hidden link
You want to be able to filter posts by date, but you want the filter to appear the same as in the link you shared, where "dates" are in a dropdown with the month and year, e.g. November 2020 etc. Is that right?
If you use a Types date field you are adding a date as a point in time, e.g. midnight November 1, 2020, so you can use that kind of filter. To filter for November you would effectively need to add a range filter, between 00:00 November 1, 2020 and 24:00 November 30, 2020.
So a taxonomy would likely work better for your example.
You have a taxonomy called, say, Publish Date, and then you add terms for each month/year, and then assign those to the posts.
But then that brings us to your question about ordering these in the dropdown. You would have to include something in the slug to force the correct order.
So if you added a term "November 2020" you should specify that its slug is 202011, and if you do the same for all terms then when you choose to order by slug they will be in the required order.
