Now, copy the formula to all the cells below to add minutes to all the time cells.

2. Use of Excel TIME Function

The TIME function in excel allows creating a time by specifying individual components like hours, minutes, and seconds. This function is also useful to add to the existing time. This is especially true if you have to assemble this function inside another formula. Note that the individual time components have to be integers and not decimals.


2.1 Add Hours

To add an additional hour, insert the formula below in cell C5:

=B5+TIME(1,0,0)

Now, press Enter and copy this formula to the cells where you want to add hours.


2.2 Add Minutes

If we want to minutes to our existing time using the TIME function, we can use the following formula.

=B5+TIME(0,1,0)

Things to Remember

  • Remember to format the time cells as Time before inserting any data otherwise they won’t work.
  • If you want to format the time difference, you can do that by right-clicking on the required cells and selecting Format Cells.
  • If you get any #NUM! error, then it may be because you entered a negative number.
  • You might also get a #VALUE! Error if you enter a non-numeric value.
