Our Solutions:
Excel has a number of formulas that enable you to count the time between two dates. You can specify that you would like to count the difference in hours by adding a time specified to your formula or by altering the cell format in your spreadsheet. Excel also enables you to apply your formula to multiple cells simultaneously by clicking the corner of your primary formula cell and dragging it with your mouse. As long as you have a start time and an end time, Excel will be able to count the hours between them.
