Add Time in Excel Using the Addition Operator
The addition operator is the basic method to add time to a duration or a time in a day in Excel.
However, the formatting of the input values is a critical variable for accurate results. You must apply custom cell formatting to appropriately express time values in an Excel cell. Otherwise, you might get incorrect results. While you can manually correct a few incorrect time calculations doing the same for a large dataset is truly challenging.
![Project table](http://cdn-5a6cb102f911c811e474f1cd.closte.com/wp-content/uploads/2024/01/Project-table.png)
Suppose you’ve got a dataset resembling the above table. You need the updated duration for projects in column D.
![The addition operator to add time](http://cdn-5a6cb102f911c811e474f1cd.closte.com/wp-content/uploads/2024/01/The-addition-operator-to-add-time.png)
Go to the first cell where you’d like to calculate the addition of a time to a duration in Excel. Enter the following formula into the cell:
=B2+C2
Hit Enter to get the updated duration.
![Using the fill handle](http://cdn-5a6cb102f911c811e474f1cd.closte.com/wp-content/uploads/2024/01/Using-the-fill-handle.png)
Now, use the fill handle of the first cell and drag it down the column to get the new time durations for the rest of the cells.
If the input duration values aren’t in the right format, you won’t get the results displayed above. Hence, you must transform your input data before performing the above calculation.

Highlight all the duration values in your worksheet. Press Ctrl + 1 to bring up the Format Cells dialog.
In the Format Cells dialog, go to the Number tab and click on the Time category. Inside the Type list on the right side, choose numbering code 37:30:55. Click OK to apply the time formatting.
Add Time in Excel Using the SUM Function
The SUM function is suitable when you need to add durations of subtasks to get the total duration of the project.
![Add time in Excel using SUM](http://cdn-5a6cb102f911c811e474f1cd.closte.com/wp-content/uploads/2024/01/Add-time-in-Excel-using-SUM.png)
Go to the cell where you want to sum up a bunch of time entries in HH:MM:SS format. Copy and paste the following formula into the cell and hit Enter:
=SUM(B2:B6)
You should customize the above SUM formula depending on the dataset you’re working on. If the input durations aren’t in the appropriate format of time values, use the Format Cells dialog to reformat the time entries.
Add Time in Excel Using the TIME Function
The TIME function in Excel is a useful tool for manipulating and working with time values. It allows you to create time entries by specifying the hour, minute, and second components.
The syntax for the TIME function is pretty straightforward: =TIME(hour, minute, second).
For example, to represent 3:30 PM, you would use =TIME(15, 30, 0), provided that the cell formatting is h:mm AM/PM.
This function is particularly handy when dealing with time-based calculations or when combining durations with other functions to perform complex operations.
You can use the TIME function to create a data entry form where employees can update extra hours, minutes, and seconds of projects and tasks to get the new project duration for accurate billing. here, you’ll add hours, minutes, and seconds to an existing time duration.
This method is more flexible than the ones explained so far because you don’t need to apply any custom cell number formatting. The TIME function will automatically express the resulting duration in HH:MM:SS format.
![Example of a project duration dataset](http://cdn-5a6cb102f911c811e474f1cd.closte.com/wp-content/uploads/2024/01/Example-of-a-project-duration-dataset.png)
Suppose you’ve got or want to create an Excel worksheet that will contain a column for existing durations of projects or sub-projects. Then, there will be three columns for data entry of additional hours, minutes, and seconds used by by the projects or sub-projects. Finally, there will be another column for the total duration or updated completion time.
![A TIME formula](http://cdn-5a6cb102f911c811e474f1cd.closte.com/wp-content/uploads/2024/01/A-TIME-formula.png)
In the first cell of the total duration column, enter the following formula and hit Enter to easily add time in Excel:
=B2+TIME(C2,D2,E2)
Do change the cell references according to your own Excel worksheet.
![A TIME formula](http://cdn-5a6cb102f911c811e474f1cd.closte.com/wp-content/uploads/2024/01/Fill-handle-copied-formula.png)
To apply the same formula to the rest of the cells in the column, simply drag the fill handle down the column until there are reference cell values in the adjacent columns.
![Fill handle copied formula](http://cdn-5a6cb102f911c811e474f1cd.closte.com/wp-content/uploads/2024/01/Adding-time-to-Excel-using-TIME.png)
Now, as you keep entering the values in Hour, Minute, and Second columns, Excel will add up the values automatically and populate the result in the cell you selected.
Add Time to AM/PM Format Using the TIME Function
Imagine you’re overseeing a bus service schedule in an Excel worksheet. Your goal is to precisely monitor delays in the start times of services across different bus routes.
![Sample dataset](http://cdn-5a6cb102f911c811e474f1cd.closte.com/wp-content/uploads/2024/01/Sample-dataset.png)
In this scenario, your primary task involves incorporating hours, minutes, or seconds to the original start times, which are typically in AM/PM format. This ensures accurate tracking of delayed service durations, allowing for effective management of the bus schedule.
You can customize your worksheet according to the above example to have three distinct columns for time entries. These columns are the Start Time for AM/PM time entries, the Delayed BY column for hour, minute, or second, and the New Start Time column where you’ll do the calculations.
![Using a TEXT and TIME combo](http://cdn-5a6cb102f911c811e474f1cd.closte.com/wp-content/uploads/2024/01/Using-a-TEXT-and-TIME-combo.png)
Now, highlight the first cell below the New Start Time column and enter the following formula into it:
=TEXT(B2 + TIME(0,C2,0),"h:mm AM/PM")
Hit Enter to get the calculated time value.
![Apply formula to multiple cells](http://cdn-5a6cb102f911c811e474f1cd.closte.com/wp-content/uploads/2024/01/Apply-formula-to-multiple-cells.png)
Drag the fill handle down the column to copy and paste the same formula for all the bus routes.
Don’t forget to customize the cell references in the above formula according to your own dataset. The current formula only adds minutes to an AM/PM time format.
If you need to add hours, use this formula:
![TEXT TIME combo for hour](http://cdn-5a6cb102f911c811e474f1cd.closte.com/wp-content/uploads/2024/01/TEXT-TIME-combo-for-hour.png)
=TEXT(B2 + TIME(C2,0,0),"h:mm AM/PM")
Or, you might need to add seconds, so use this formula:
![TEXT TIME combo for second](http://cdn-5a6cb102f911c811e474f1cd.closte.com/wp-content/uploads/2024/01/TEXT-TIME-combo-for-second.png)
=TEXT(B2 + TIME(0,0,C2),"h:mm:ss AM/PM")
