1. Using Arithmetic Operator to Subtract 30 Minutes from a Time in Excel

In our very first method, we will perform subtraction using a simple formula. It’s simple and easy, just follow along.

Steps:

• At the very beginning, create a new column Total Time between columns Out Time and Lunch Time. Basically, it sits on Column E.

• Then, write down the following formula.

Here, C5 and D5 represent the In Time and Out Time of Robin consecutively.

• After that, press the ENTER key.

• Now, bring the cursor to the bottom right corner of cell E5. Thus, it’ll look like a plus (+) sign. It’s the Fill Handle tool.
• Then, double-click on it.

• Automatically, it copies the formula to the lower cells. Hence, we also get the results in the remaining cells also.

• At this moment, we’ll change the format of Lunch Time into h:mm.
• For this, select cells in the F5:F14 range.
• Later, press CTRL + 1 on the keyboard.

• Suddenly, the Format Cells dialog box opens.
• Here, go to the Number tab.

However, the fraction formula is not required when the minute input is in the right format like Method 1, which is the minute format. So, without further delay, let’s dive in!

Steps:

• In the first place, select cell G5.

Sub subtract_30()
Dim in_time As Date, out_time As Date
Dim total_time As Date
For x = 5 To 14
in_time = Cells(x, 3).Value
out_time = Cells(x, 4).Value
total_time = out_time - in_time - Cells(x, 5).Value
Cells(x, 6).NumberFormat = "hh:mm"
Cells(x, 6).Value = total_time
Next x
End Sub

• Lastly, select the Run icon or press F5 on the keyboard.

• Now, return to the VBA worksheet.
