5 Ways To Calculate Years Between Dates In Excel

Working with dates in Excel can be a challenge, especially when you need to calculate the years between two dates. This is a common task in various fields, such as finance, human resources, and project management. Fortunately, Excel provides several ways to calculate the years between dates, and in this article, we will explore five methods to achieve this.

Understanding Date Calculations in Excel

Before we dive into the methods, it's essential to understand how Excel handles dates. Excel stores dates as serial numbers, starting from January 1, 1900, which is represented as 1. This means that each subsequent day is represented by a unique serial number. For example, January 2, 1900, is represented as 2, and so on.

Method 1: Using the YEAR Function

The YEAR function is a simple way to extract the year from a date. You can use this function to calculate the difference in years between two dates.

Here's the formula:

=YEAR(B2) - YEAR(A2)

Assuming the start date is in cell A2 and the end date is in cell B2.

Method 2: Using the DATEDIF Function

The DATEDIF function is a more powerful function that can calculate the difference between two dates in various units, including years.

Here's the formula:

=DATEDIF(A2, B2, "y")

Assuming the start date is in cell A2 and the end date is in cell B2.

Method 3: Using the DATE Function

The DATE function can be used to calculate the difference between two dates by creating a new date that represents the start date plus the number of years you want to add.

Here's the formula:

=DATE(YEAR(B2), MONTH(B2), DAY(B2)) - DATE(YEAR(A2), MONTH(A2), DAY(A2))

Assuming the start date is in cell A2 and the end date is in cell B2.

Method 4: Using VBA Macro

If you prefer to use VBA macros, you can create a custom function to calculate the years between two dates.

Here's the code:

Function YearsBetweenDates(startDate As Date, endDate As Date) As Integer
    YearsBetweenDates = DateDiff("yyyy", startDate, endDate)
End Function

You can then use this function in your worksheet like any other function:

=YearsBetweenDates(A2, B2)

Method 5: Using Power Query

Power Query is a powerful tool in Excel that allows you to manipulate and analyze data. You can use Power Query to calculate the years between two dates.

Here's the formula:

=Date.Year([EndDate]) - Date.Year([StartDate])

Assuming the start date is in column [StartDate] and the end date is in column [EndDate].
