Monthly Totals with multiple date ranges

I am trying to make a table of all vacations by month. Cells F21:F35 have the total days per request and I'd like to keep the total by month in Column B. I'd also like to only total them if Column G says Approved. I stopped in Feb 2024 but as more come in in future months, Columns A & B will get bigger.

I manually entered the totals in F2:F17 while I was trying various formulas but none seemed to give me the right answers.
I also highlighted one particular request in Row 34. There will be some requests that start in one month and end in another.
