I want to filter the Calender in my SharePoint 2010. All Items with a Enddate older than 7 days must be hidden. I found no way to modified the Calender View to filter the elements because the field "Enddate" is not in list.
If it's anything like 2007, you need to do some Tomfoolery to make it work.
Create a calculated column called EndDateFilter and make it simply =[End Date]. Then filter the calendar view by EndDateFilter is less than or equal to [Today]+7.
