MSP begins a new week on Saturday at 2:00 PM instead of 12:00 AM on Saturday. Generally, we have found that this is the way most of the churches we work with would like their services to be grouped. However, you can control this option when exporting a schedule in any view that can be grouped by week.
1. Go to File - Export Schedule...
2. In the Layout Settings pane, look for the checkbox that says "Group services together by week"
3. Where it says "(start week: Sat, 2:00 PM)" click the blue link
4. Reset the start of the new week to the day (Saturday or Sunday) and time you want
5. Click OK and Export Schedule
