Calculating Age From a Date of Birth in Excel

Calculating age from a date of birth in Excel is a simple task that can be accomplished with the built-in DATEDIF function. This function is capable of calculating the difference between two dates in any unit of time, including years, months, and days. This article will explain how to use the DATEDIF function to calculate age from a date of birth in Excel.

Creating an Excel Spreadsheet

The first step in calculating age from a date of birth in Excel is to create an Excel spreadsheet. The spreadsheet should contain two columns: one for the date of birth and one for the age. Each row in the spreadsheet should contain a date of birth and the corresponding age. It is important to format the date of birth column as a date so that Excel can accurately calculate the age.

Using the DATEDIF Function

Once the spreadsheet is created, the next step is to use the DATEDIF function to calculate the age. This function takes three arguments: the start date, the end date, and the unit of time. In this case, the start date will be the date of birth and the end date will be the current date. The unit of time will be “y” for years. The formula for the DATEDIF function is as follows: =DATEDIF(start date, end date, “y”).

Formatting the Results

The final step in calculating age from a date of birth in Excel is to format the results. The results of the DATEDIF function will be a number, which can be formatted as a number or a date. To format the results as a date, right-click on the cell containing the results and select “Format Cells.” Then select the “Number” tab and select “Date” from the list of available formats. This will format the results as a date.

Updating the Age Automatically

The age calculated using the DATEDIF function will remain static until the spreadsheet is updated. To update the age automatically, the formula can be modified to include the TODAY function. This function will return the current date, which can be used as the end date in the DATEDIF formula. The modified formula is as follows: =DATEDIF(start date, TODAY(), “y”). This will update the age automatically each time the spreadsheet is opened.

Using Conditional Formatting

Another useful feature in Excel is the ability to use conditional formatting to highlight cells containing certain values. This can be used to highlight cells containing a person’s age. To do this, select the cells containing the age and then select “Conditional Formatting” from the “Home” tab. Then select “New Rule” and select “Format only cells that contain” from the list of available options. Finally, select the desired criteria and the desired formatting.

Making Calculations Easier

The DATEDIF function can also be used to make calculations easier. For example, the DATEDIF function can be used to calculate the number of days, months, or years between two dates. This can be useful for determining how long someone has been alive or how many days until a certain event. The formula for this is as follows: =DATEDIF(start date, end date, “d”). This will return the number of days between the two dates.

Using the AGE Function

The AGE function is another useful function for calculating age from a date of birth. This function takes two arguments: the date of birth and the date to calculate the age from. The formula for the AGE function is as follows: =AGE(date of birth, date to calculate age from). This function can be used instead of the DATEDIF function if the start date and end date are the same.

Storing the Date of Birth in a Cell

The date of birth can also be stored in a cell and then used as an argument in the AGE function. This can be useful if the date of birth is entered into the spreadsheet but not formatted as a date. To do this, the cell containing the date of birth must be formatted as text. Then the cell can be used in the AGE function. The formula for this is as follows: =AGE(date of birth cell, date to calculate age from).

Using the YEARFRAC Function

Finally, the YEARFRAC function can be used to calculate the number of years between two dates. This function takes two arguments: the start date and the end date. The formula for the YEARFRAC function is as follows: =YEARFRAC(start date, end date). This function can be used instead of the DATEDIF function if the unit of time is years.
