If you are not familiar with creating collections you can find more information here
Note: If the event is a reoccurring event that was created before the creation date defined but also includes future dates it will be listed as well. So the dates you see on a listed event necessarily won't show as a past date for reoccurring events. Just know that the event was created before the date you have defined. This only applies to reoccurring events and is not an issue with pages or News Items.
This Search term can be easily be modified to search for pages. news Items and more by changing the Type of item your looking for. The same applies for the "Before Date" you can change that date to reflect any before date.
