I need to calculate the average client visit days for our sales staff & I'm
stumped. Last year I entered each week's total visit days separately and my
spreadsheet was large. This year I thought I'd be clever and enter a monthly
total instead.

I created an abbreviated example of my spreadsheet below. I feel silly, but
I can't figure out how to get the average visit days per week based on the
total visit days per month. Can you help with the calculation formula?
Thanks!

Visit days per week: ?
Total visit days : 25
