Next starting time calculation

Hi all,

I believe someone already asked this question but I cannot find it or figure out how to calculate time in Excel 2007.
Here is the example:

column C represent start time in hh:mm format
column D represent job hours

all I need is a formula to calculate what time the next job starts, so C7 is 08:00, D7 is 10, Ideally I`d like to get 18:00 in the column C8 automatically after D7 is updated.

Going forward I`d love to update the column D only with number of hours for the job required and get starting time.

thanks

Excel does hours in a decimal system. 24hours = 1
6 hours is = 6/24 = 0.25
I hope this helps.

I did just do an answer that you can look at which might point you in the right direction
