Grouping by dates- Pivot table-

I have Excel 2010- I odn't have the analyze-insert timeline- available. SO with that being said. I was wondering if there was a way to show how many jobs were completed within 1 weeks time. The week of course would begin on a Sunday and end on a Friday. I attempted to do this and I just couldn't get the actual number per week. Please anything at this point would be helpful. Please see the attached sample sheet.
