Count the number of files that contain a specific tag in dataview

About dataview I would like to use dataview to count the number of files with a particular tag in the daily notebook files created this year, by month.
In the front matter of all daily notebook files, there is a date, and the year and month are filled in, so I want to narrow it down from there.
For example, if I want to count the number of files with the tag #I’m not feeling well

January 10

February 5

March 9

April 10
etc…

I would like to be able to display something like Does anyone know of a code that can do this?
I am using deepl, so apologies if the text is unnatural! Thank you for viewing!
