## Calculating Age from DOB in Excel

Age is a very important factor when it comes to dealing with data. Knowing the age of a person is often necessary to make decisions. Excel provides the formula to calculate the age from the date of birth. The formula uses the DATEDIF function which takes a start date and an end date and calculates the difference between the two. This function can be used to calculate the age from the date of birth.

To use the DATEDIF function, the user needs to provide the start date, which is the date of birth in this case, and the end date which is the current date. The resulting value is the number of years, months, and days between the two dates. This value is then divided into the years, months, and days to get the exact age that the person is.

### Steps to Calculate Age from DOB in Excel

#### Step 1: Enter the Date of Birth
