How to Add Hours to Time in Excel (8 Quick Ways)

If you want to add hours to time in Excel easily, then you can follow this article to learn various ways to do this job. So, let’s get into the main article to explore those ways.

How to Add Hours to Time in Excel: 8 Ways

Here, we have the following two datasets; one is for the Entry Time, and working Time Period of the employees of a company and the other contains the records of the Order Time, Duration between the order time, and delivery time of the products of another company.
Using these datasets, we will illustrate the ways to add hours to time in Excel easily.

We have used the Microsoft Excel 365 version here, you can use any other version according to your convenience.

Method-1: Add Hours to Time in Excel for Less than 24 Hours

Here, we will normally add the Entry Time with the Time Period to get the Exit Time of the employees, and here the results after summing up will be less than 24 hours so no extra step will be needed here.
For adding up the times simply with the addition operator you have to keep both of the values in Time format like below.

Steps:
➤ Use the following formula in cell E5.

Here, C5 is the Entry Time, and D5 is the Time Period.

➤ Press ENTER and drag down the Fill Handle tool.

After adding up hours with the Entry Times we are getting the following Exit Times.

Method-2: Add Hours to Time in Excel for More than 24 Hours

To get the Exit Times more than 24 hours after adding up hours with the Entry Times, we have increased the hours of the Time Periods in this example.

Steps:
➤ Use the following formula in cell E5.

Here, C5 is the Entry Time, and D5 is the Time Period.

➤ Press ENTER and drag down the Fill Handle tool.

So, we can see that after adding up values we are not getting our expected Exit Times because for equal to or more than 24 hours Excel will consider 24 hours into a day and then show up only the remaining hours and minutes as results.

To solve this problem select the Exit Times and then go to Home Tab >> Number Format dialog box symbol.
You can go there also by clicking CTRL+1.

Then the Format Cells dialog box will pop up.
➤ Go to Number Option >> Custom Option >> write [h]:mm in the Type box >> press OK.

Afterward, we will get our real added values for more than 24 hours.

Method-3: Add Hours to Time in Excel Using the TIME Function

Here, we will use the TIME function to add up hours with the Entry Times to get the Exit Times and you can keep the hours of the Time Periods in General format here.

Steps:
➤ Type the following formula in cell E5.

Here, C5 is the Entry Time, and D5 is the Time Period.

➤ Press ENTER and drag down the Fill Handle tool.

Finally, we are getting the Exit Times after adding up the hours of the Time Periods with the Entry Times.

Method-4: Add Hours to Time in Excel for Negative Hours

Suppose, we have some negative hours as Time Periods and here we will add these negative hours with the Entry Times.

Though it’s quite unusual to have a negative time period, we are showing through this dataset to maintain consistency and simplicity.

Steps:
If we use the following formula like the previous method, then we will have #NUM! error due to the negative results as time can’t be negative.

So, we will solve this problem by using the following formula

Here, C5 is the Entry Time, and D5 is the Time Period.

➤ Press ENTER and drag down the Fill Handle tool.

Instead of getting #NUM! error, now, we are adding up to 24 to those negative values.

Method-5: Add Hours to Time in Excel for a List of Date Time

Here, we have the date and time combinations in the Order Time column, and with these times we will add up the hours of the Durations to get the Delivery Times.

Steps:
If we use the following formula then instead of adding hours we will add the duration to the days,

We can rectify that formula by dividing the hours of the Durations by 24 to convert the day into hours. (1 day = 24 hours)

➤ Press ENTER and drag down the Fill Handle tool.

As a result, we can successfully add the hours to the Order Times to get the Delivery Times (m-d-yy h: mm AM/PM) now.

➤ Press ENTER and drag down the Fill Handle tool.

Eventually, we are getting the Delivery Times for the products.

=TIME(MOD(D5,24),0,0)+C5+INT(D5/24)

Method-8: Using a VBA Code to Add Hours to Time in Excel

Here, we will use a VBA code to add up the Duration hours with the Order Times to get the Delivery Times.

Steps:
➤ Go to Developer Tab >> Visual Basic Option.

Then, the Visual Basic Editor will open up.
➤ Go to Insert Tab >> Module Option.

After that, a Module will be created.

➤ Write the following code

Function Houraddition(value As String, x As Integer) As String

Dim dt1 As Date
dt1 = CDate(value)
dt1 = DateAdd("h", x, dt1)
Houraddition = Format(dt1, "m/d/yy hh:mm AM/PM")

End Function

This code will create the function Houraddition, CDATE will convert the given value into a date and DATEADD will add the hour value to this date. Finally,  will give our desired format to this date-time.

Now, go back to the sheet and write the following formula in cell E5

Here, C5 is the Order Time, D5 is the Duration and Houraddition will add up the Duration to the Order Date.

➤ Press ENTER and drag down the Fill Handle tool.
