For the table above, I would like to return the dates corresponding to the first and last values in the row.
For example, Start Date for category A would Feb-20, End Date Apr-20.

Array formulas
Entered with Ctrl+Shift+Enter. If entered correctly, Excel will surround with curly braces {}.
Note: Do not try and enter the {} manually yourself.
