When you have dragged your date to the row or column, right click and select field setting. You go to the field settings, and instead of date you select custom settings, and after that you can select exactly how you want to show your dates.
In my case it was enough to select the date setting, and the setting you asked for was there directly
Do you want to show dates from 1-5 as a grouping? Or do you want to show day by day?. The first one you can see above, while the second one I need some extra info about.
