Calculating age can be a tedious task, but with the use of Excel, it can be done in just a few clicks! In this article, we will show you different ways on how to calculate age in Excel, whether it be in years, months, or even days!
Method 1: Using the DATEDIF Function
The DATEDIF function stands for Date difference, and as the name suggests, it calculates the difference between two dates. In this case, we will be using it to calculate the age of a person. Here is the syntax for the DATEDIF function:
=DATEDIF(start_date,end_date,unit)
The start_date is the first date, while the end_date is the second date. The unit is the interval type, such as months, years, or days. For example, if you want to calculate the age of someone in years, you would enter “Y” as the unit.
Let’s say we have the birthdate of a person in cell A1, we can use the DATEDIF function to calculate their age like this:
=DATEDIF(A1,TODAY(),"y")
The TODAY() function is used to get the current date, so it could accurately calculate the age. The “y” in the formula tells Excel that we want to calculate it in years.
Method 2: Using the YEARFRAC Function
The YEARFRAC function calculates the fraction of a year between two dates. The syntax for the YEARFRAC function is:
=YEARFRAC(start_date,end_date,basis)
The start_date and end_date are the two dates you want to calculate the age difference between, and the basis is optional. If you leave it blank, it will default to the US method of calculating fractions of years.
Using the same example as before, we can calculate the age of a person using the YEARFRAC function like this:
=YEARFRAC(A1,TODAY())
This formula calculates the age of the person by calculating the fraction of a year between their birthdate and today’s date.
Method 3: Using the INT and DATEDIF Functions
If you want to calculate the age of a person in years, months, and days, you can use the INT and DATEDIF functions together. Here’s how:
=INT(DATEDIF(start_date,end_date,"y")&" years, "&DATEDIF(start_date,end_date,"ym")&" months, "&DATEDIF(start_date,end_date,"md")&" days")
In this example, we will calculate the age of a person in years, months, and days, and then concatenate the results into a single text string. The INT function is used to round down the calculated age to a whole number.
Frequently Asked Questions (FAQs)
Q: Can I calculate the age of a baby who hasn’t been born yet?
A: No, you cannot calculate the age of a baby who hasn’t been born yet because the DATEDIF and YEARFRAC functions require two dates to calculate the difference. However, you can use the formula to calculate the number of days until the baby’s due date, and then estimate the age once the baby is born.
Q: How accurate are these formulas?
A: These formulas are accurate to the day. However, because months have varying lengths, it is possible to have some discrepancies when calculating the age in months. For example, a person who was born on October 31st, 2021, and another person who was born on November 1st, 2021, are both one month old on November 30th, 2021, even though they were born on different days.
