There are several functions in Excel that deal with time. However, there is no special function for calculating the difference between two times variables. While you may know, a time value is a numeric value that is represented as time, subtracting one value from another produces a decimal number, which must be structured as time again. In this tutorial, we’ll show you how to calculate the time difference between AM and PM in Excel by applying formulas.

## 6 Ways to Calculate Time Difference Between AM and PM in Excel

We’ll go through six different approaches to compute the time difference in the sections below. We estimated the time difference in a variety of units, including hours, minutes, seconds, and also for negative values. A sample Data set is provided to do the task.

### 1. Use Formula to Calculate Time Difference Between AM and PM in Hours and Minutes

Follow the instructions below to determine the time difference in hours and minutes.

**Step 1:**

- To subtract the difference from end time to start time, type the following formula in cell
**D5**.

`=C5-B5`

**Step 2:**

- Press
**Enter**.

**Step 3:**

**AutoFill**the rest cells with the same formula and get the final results.

**Notes.** Look carefully that the difference is shown in **AM/PM** units. But, if you want to show it just the time difference with hours/minutes, you need to change the format. To change the format follow the procedure.

**Step 1:**

- Press
**Ctrl**+**1**to open the**Format cells**dialog box. - Click on the
**Time**option and select the**Format**as shown in the image below. - Finally, click on
**OK**.

- Therefore, the time difference will be shown in
**hh:mm.**

### 2. Calculate Time Difference Between AM and PM in Hours in Numbers by Applying Formula

The time difference is usually formatted as the **Time **format. We can’t calculate the difference in hours in decimal numbers in this format. As a result, you must change the format to the Number format. Follow these easy steps to complete the task.

**Step 1:**

- Firstly, type the formula in cell
**D4**.

`=(C5-B5)*24`

**Step 2:**

- From the
**Number**tab, select the**Number.**

**Step 3:**

- Therefore, you will find the hours will be changed to decimal numbers.

**Step 4:**

- Repeat the procedure for all cells in the column.

### 3. Apply the INT function to Calculate Time Difference Between AM and PM in Completed Hours

For counting the time difference in a marginal figure we will apply the **INT function **with the previous method. Follow the steps outlined below to get it done.

**Step 1:**

- Firstly, enter the following formula.

`=INT((C5-B5)*24)`

**Step 2:**

- Then, press the

### 4. Use Formula to Calculate Time Difference Between AM and PM in Minutes

We need to multiply the hour by **1440 **to get the time difference in minutes. Follow the steps outlined below to see how we did it.

**Step 1:**

- To calculate in minutes, write the formula in the formula bar.

`=(C5-B5)*1440`

**Step 2:**

- Then, press
**Enter**to the first result.

**Step 3:**

- Finally, fill up the required cells applying the same.

**Notes.** Remember that the tome Format has to be in the Number format.

### 5. Apply Formula to Get Time Difference Between AM and PM in Seconds

Additionally. we have to multiply the hours by **86400 **to get the hours minutes. Follow the instructions below to get the answers in the unit of seconds.

**Step 1:**

- At first, type the formula in cell
**D5**.

`=(C5-B5)*86400`

**Step 2:**

- Then, to see the result press
**Enter**.

**Step 3:**

- Therefore, repeat the steps again to fill up the required cells.

### 6. Apply the IF Function to Calculate Time Difference Between AM and PM for Negative Value

Importantly, the previous formulas won’t work if the end time is less than the start time. So, we will apply the conditional function **IF**. Follow the steps to know how to use it.

**Step 1:**

- First of all, write the following formula.

`=IF(C5>B5,C5-B5, (1-B5+C5))`

**Step 2:**

- Secondly, press
**Enter**to see the value.

**Step 3:**

- Finally, fill up the cells you need.

**Notes. ** Adding **1** means to add **24** hours in decimal point. By adding **1**, we convert the negative with a positive interval.
