By default, in Calendar, when you click Week or Month, the calendar displays Monday, Tuesday, Wednesday, Thursday, and Friday, and Saturday and Sunday are compressed and shown half the size of the other five days. You can change the display of the Month view so that Saturday and Sunday are shown the same size as other days of the week. You cannot modify the Week view.

1. In Calendar, right-click a blank area of the calendar grid, and then click Other Settings on the shortcut menu.
2. In the Format Day/Week/Month View dialog box, under Month, clear the Compress weekend days check box.
