I have a calendar of events that we use to track when people will be out for Vacation. The only columns in the list are Title, StartDate, EndDate. If I create an event that last a month, then create one that last a week, then create an even that last more than 2 days but less that a week, the even that is 2 days will not display on the monthly view. I can click on the individual days and it's there. Here is a specific example. - Create even for Title: User VAC Monthly StartDate: 7/01/2010 EndDate: 7/30/2010 - Create even for Title: User VAC 1 StartDate: 7/28/2010 EndDate: 7/30/2010 - Now Create even for Title: User VAC 3 StartDate: 7/23/2010 EndDate: 7/30/2010 If I look at the Monthly view of the Calendar it will not show the entry for User VAC 3. Does anyone have any idea why this would happen and what I can do to fix it. The expand/collapse links do not have any affect on the items. Thanks

I've determined this only happens when you are using a Calendar View of a Custom SharePoint list.

Apparently there is an issue with using a calendar view on a custom list. I resolved my problem by creating a new calendar list and copying my data from the custom list to it. The calendar list displays everything as I would expect it to.
