# How to Calculate Difference in Dates in Excel?

Do you ever find yourself needing to calculate the difference between two dates in Excel? Whether you’re a finance manager keeping track of transactions or a project manager monitoring deadlines, Excel can be a powerful tool to help you quickly and accurately measure the difference between two dates. In this article, we’ll show you how to calculate difference in dates in Excel in just a few simple steps.

## Understanding the Date Difference Function in Excel

Excel is a powerful tool for data analysis and manipulation. One of its many features is the ability to calculate the difference between two dates in days, months, and years. This article will explain how to use the date difference function in Excel to determine the difference between two dates.

The date difference function in Excel is a simple formula that can be used to quickly and accurately determine the amount of time between two dates. The formula takes two dates, subtracts them, and then returns the amount of time between in days, months, and years. This makes it easy to compare dates, such as the start and end dates of a project, or to calculate the amount of time between two events.

The formula for calculating the difference between two dates is simple. It requires the two dates in question, as well as a unit of time to measure the difference. The options for units of time include days, months, and years. Once these values are entered, the formula will calculate and return the amount of time between the two dates.

### Using the Date Difference Function in Excel

Using the date difference function in Excel is a straightforward process. First, two dates must be entered into two separate cells. Then, the formula for the date difference function must be entered into a third cell. The formula should include the two dates and the unit of time to measure the difference. Once the formula is entered, the result will be automatically calculated and returned.

The formula for the date difference function is as follows: =DATEDIF(start date, end date, unit of time). For example, if the start date is in cell A1 and the end date is in cell B1, the formula would be =DATEDIF(A1,B1,”y”). This formula would calculate the difference between the two dates in years.

### Using the Date Difference Function in Other Formulas

The date difference function in Excel can also be used in other formulas. For example, it can be used to calculate the amount of time between the start and end dates of a project, or to determine the amount of time between two events. The formula can also be used to calculate the age of a person, or to compare two dates to see which is earlier or later.

The formula for using the date difference function in other formulas is the same as the formula for calculating the difference between two dates. However, the formula must be adjusted to include the additional parameters for the other formula. For example, if the formula for calculating the amount of time between two events is =Hours(start date, end date), the formula must be adjusted to include the additional parameter for hours. The formula would then be =Hours(DATEDIF(start date, end date, “h”)).

## Calculating the Difference Between Two Dates in Days, Months, and Years

Calculating the difference between two dates in days, months, and years is a simple process that can be done using the date difference function in Excel. To calculate the difference, two dates must be entered into separate cells, and then the formula for the date difference function must be entered into a third cell. The formula should include the two dates and the unit of time to measure the difference.

Once the formula is entered, the difference between the two dates will be calculated and returned in the unit of time specified. For example, if the unit of time is days, the difference will be returned in days; if the unit of time is months, the difference will be returned in months; and if the unit of time is years, the difference will be returned in years.

### Calculating the Difference Between Date Ranges

Calculating the difference between two date ranges is similar to calculating the difference between two dates. Instead of entering two dates into separate cells, two date ranges must be entered. For example, if the date range is from 1/1/2020 to 12/31/2020, the formula would be =DATEDIF(1/1/2020, 12/31/2020, “y”). This formula would calculate the difference between the two dates in years.

### Calculating the Difference Between Date Strings

Calculating the difference between two date strings is similar to calculating the difference between two dates. However, instead of entering two dates into separate cells, two date strings must be entered. For example, if the date string is “1/1/2020 to 12/31/2020”, the formula would be =DATEDIF(“1/1/2020”, “12/31/2020”, “y”). This formula would calculate the difference between the two dates in years.

## Using the Date Difference Function in Other Formulas

The date difference function in Excel can also be used in other formulas. For example, it can be used to calculate the amount of time between the start and end dates of a project, or to determine the amount of time between two events. The formula can also be used to calculate the age of a person, or to compare two dates to see which is earlier or later.

The formula for using the date difference function in other formulas is the same as the formula for calculating the difference between two dates. However, the formula must be adjusted to include the additional parameters for the other formula. For example, if the formula for calculating the amount of time between two events is =Hours(start date, end date), the formula must be adjusted to include the additional parameter for hours. The formula would then be =Hours(DATEDIF(start date, end date, “h”)).

## Few Frequently Asked Questions

### What is the Formula to Calculate Difference in Dates in Excel?

The formula to calculate the difference between two dates in Excel is =END_DATE – START_DATE. This formula will return the number of days between the two given dates. For example, if the start date is 1/1/2018 and the end date is 1/10/2018, the formula would be =1/10/2018-1/1/2018, which would return 9.

### How Do I Calculate Duration Between Two Dates in Excel?

To calculate the duration between two dates in Excel, you first need to calculate the difference between the two dates. To do this, you can use the formula =END_DATE – START_DATE. Once you have the number of days between the two dates, you can then use the DATEDIF function to calculate the duration in a specific unit of time such as months, years, or days. For example, if you wanted to calculate the duration in months, you would use the formula =DATEDIF(START_DATE, END_DATE,”m”).

### What is the Best Way to Format the Date Difference in Excel?

The best way to format a date difference in Excel is to use the DATEVALUE function. This function will convert a text string into a date value. For example, if you have a date difference of 9 days, you can use the formula =DATEVALUE(“9d”) to format the date difference as 9 days.

### What is the Shortcut Key to Calculate Difference in Dates in Excel?

The shortcut key to calculate the difference between two dates in Excel is to press the F9 key while the formula is selected. This will cause Excel to recalculate the formula and display the result.

### How Can I Automatically Calculate Date Difference in Excel?

To automatically calculate the date difference in Excel, you can use the formula =END_DATE – START_DATE. You can then set up the spreadsheet to automatically calculate the difference when the start date or end date is changed. To do this, you can select the formula cell and then click the “Data” tab in the ribbon. In the “Data Tools” section, click the “Formulas” button and then select the “Calculation Options” button. Finally, select the “Automatic” option and the date difference will be automatically calculated.

### Can I Use a Function to Calculate Date Difference in Excel?

Yes, you can use the DATEDIF function to calculate the date difference in Excel. The DATEDIF function allows you to specify a unit of time to calculate the difference in, such as months, years, or days. For example, if you wanted to calculate the difference in months, you would use the formula =DATEDIF(START_DATE, END_DATE,”m”). This formula will return the number of months between the two specified dates.
