#### FAQ – Pearson age calculator

### How do you calculate age formula?

The formula for calculating age based on a given date of birth and a reference date (such as today’s date) is:age = (reference date – date of birth) / 365.25Here, the “reference date” is the date for which you want to calculate the age, and the “date of birth” is the person’s birthdate.The division by 365.25 is used to account for leap years, which occur every 4 years. This helps to make the age calculation more accurate.Note that this formula assumes that the person has already had their birthday this year. If the person has not yet had their birthday this year, you would need to subtract an additional 1 from the result.Also, keep in mind that this formula only provides an approximate age, as it does not take into account the exact time of birth or the number of leap seconds that have been added to the atomic clock since the person’s birth.

### How do you calculate age in mm/dd/yyyy manually?

To calculate age in mm/dd/yyyy format manually, follow these steps:Subtract the birth year from the current year to find the difference in years.If the current month is greater than the birth month, then the age is simply the difference in years calculated in step 1.If the current month is equal to the birth month, compare the current day to the birth day. If the current day is greater than or equal to the birth day, the age is the difference in years calculated in step 1. If the current day is less than the birth day, subtract 1 from the age calculated in step 1.If the current month is less than the birth month, subtract 1 from the age calculated in step 1.For example, suppose someone was born on June 15, 1990, and today is February 19, 2023. Here are the steps to calculate their age:Calculate the difference in years: 2023 – 1990 = 33.Since the current month (February) is less than the birth month (June), subtract 1 from the age: 33 – 1 = 32.Therefore, the person’s age in mm/dd/yyyy format as of February 19, 2023, is 32.

### Can Excel calculate age?

Yes, Excel can calculate age using a simple formula. Assuming you have the birthdate of a person in a cell, you can use the DATEDIF function to calculate their age in years, months, or days.

Here’s an example of how to calculate someone’s age in years in Excel:Enter the birthdate of the person in one cell (let’s say A2). Make sure the date is in a date format, not in text format.In another cell (let’s say B2), enter the following formula: =DATEDIF(A2,TODAY(),”Y”)Press Enter to see the result. This formula calculates the number of whole years between the birthdate (cell A2) and today’s date (which is obtained by the TODAY function).

The result should be the person’s age in years. You can also modify the formula to calculate age in months or days by changing the last argument of the DATEDIF function to “M” or “D”, respectively.
