If you click on the "Attendance" tab, you'll be able to see a list of all of your attendance records. This list will also show days that you were tardy, or late for school. If you only want to see the days you were out of school entirely, use the "Type" filter on the left hand side. This will allow you to view only absence records.

The "Class Attendance" tab will show you which classes you've missed, even on days that you were in school.
