Hours per week label

I added an "hours per week label" to the schedule page UI. I figured this would give students an easier and more accurate method of counting up their weekly hours rather than doing it manually. 

Here is a screenshot of the changes I made to the UI:

The "if loop" on the <div class = date-range>, (the display for the dates for the current week) did not have any indent as well. So should I change the format for that as well?
