Long Answer - Video: Add Time in Excel

Long Answer:

Enter your hours and minutes in the following format:

hh:mm            example         10:20        for 10 hours, 20 minutes, OR 
hh:mm:ss        example        10:20:32     for 10 hours, 20 minutes, 32 seconds

In excel's mind:                                12 hours + 13 hours = 25 hours (in yours too?)
However it will display to you as:         12 hours + 13 hours = 1 hour (it rolls over to the next day to show a time-of-day format)
To see the correct total of hours:

Method A 

Right Click on your total   
Click on Format Cells
On the Number Tab, under "custom" change your settings to [h]:mm 
Method B

Right Click on your total
Click on Format Cells
On the Number Tab, Select "Number" and 2 Decimal Places
In your formula bar, add *24 to the end of the sum formula    (example =SUM(A20:G20)*24 )


What is the difference between Method A and Method B?

In Method A, eight and a half hours will appear as 8:30
In Method B, eight and a half hours will appear as 8.50
