Calculating time differences in Excel is one of those tasks that seems simple until you actually try it. Whether you’re tracking work hours, measuring project durations, or comparing timestamps, understanding how to work with time correctly can save you a lot of confusion and errors
Excel stores times as fractional parts of a day, which means that formulas for calculating differences behave differently than typical number calculations. If your data includes hours and minutes, especially across midnight or multiple days, you need to use the right techniques to get accurate results.
One common scenario is calculating total hours worked. For example, if an employee clocks in at 9:00 AM and clocks out at 5:30 PM, you might expect a straightforward calculation — but you also need to handle lunch breaks, overtime, and potential cross-day shifts. Excel can handle this easily if you structure your formulas correctly.
