To calculate days and hours in Excel, you can use the DATEDIF function for days and subtract the start time from the end time for hours. For days, =DATEDIF(A1, B1, "d") where A1 is the start date and B1 is the end date. For hours, =(B2-A2)*24 assuming A2 is the start time and B2 is the end time. Ensure both cells are formatted correctly; dates as 'Date' and times as 'Time'. This will give you a straightforward calculation of the difference in days and hours between two points.
