5 Simple Ways To Calculate Years Between Two Dates In Excel

Calculating the number of years between two dates in Excel can sometimes feel daunting, especially if you're not familiar with the various date functions available. But don't fret! This guide will break down five simple methods for determining the years between dates, so you can easily manage your data like a pro. 📊 Let's dive in!

Method 1: Using the DATEDIF Function

One of the easiest ways to calculate the difference between two dates is by using the DATEDIF function. This function computes the difference in days, months, or years.

Step-by-step guide:

1. Open your Excel worksheet where you want to perform the calculation.
2. In cell A1, enter your start date (e.g., 01/01/2020).
3. In cell B1, enter your end date (e.g., 01/01/2023).
4. In cell C1, enter the following formula:

   =DATEDIF(A1, B1, "Y")
   

   This tells Excel to return the difference in complete years between the two dates.

Important Notes:

<p class="pro-note">📅 Pro Tip: Ensure that the start date is earlier than the end date; otherwise, the DATEDIF function will return an error.</p>

Method 2: YEAR Function Combined with YEARFRAC

Another method involves using the YEAR function along with YEARFRAC, which is a versatile way to calculate fractions of years.

Step-by-step guide:

1. With the same dates as above in cells A1 and B1,
2. In cell C2, input the following formula:

   =YEAR(B1) - YEAR(A1)
   

3. For a more precise calculation that considers the exact number of days in the year, you can use:

   =YEARFRAC(A1, B1)
   

This gives you a decimal number, which indicates the exact years between the two dates, including fractions.

Important Notes:

<p class="pro-note">⏳ Pro Tip: YEARFRAC may return values that include decimals, so round it if you want just the whole number of years.</p>

Method 3: Using the YEAR and DATE Functions

If you want to consider only complete years without decimals, using a combination of YEAR and DATE functions can be useful.

Step-by-step guide:

1. Using the same dates in A1 and B1,
2. In cell C3, enter this formula:

   =YEAR(B1) - YEAR(A1) - (DATE(YEAR(B1), MONTH(B1), DAY(B1)) < DATE(YEAR(A1), MONTH(A1), DAY(A1)))
   

This formula checks if the end date has passed the anniversary of the start date within that year and adjusts the count accordingly.

<p class="pro-note">📈 Pro Tip: This method is particularly useful for calculating anniversaries where the exact date matters.</p>

Method 4: Using the NETWORKDAYS Function

While NETWORKDAYS is primarily designed to count working days, it can also be cleverly adapted to calculate years by counting the total days and converting them into years.

Step-by-step guide:

1. Again using your dates in A1 and B1,
2. In cell C4, enter this formula:

   =NETWORKDAYS(A1, B1) / 365
   

Important Notes:

<p class="pro-note">📉 Pro Tip: This method gives you a rough estimate of the years and may not always reflect the exact number of years due to leap years.</p>

Method 5: Custom Function in VBA (Advanced)

For those who enjoy a little coding and want a more customized approach, you can create a simple VBA function.

Step-by-step guide:

1. Press Alt + F11 to open the VBA editor.
2. Insert a new module (Insert > Module).
3. Copy and paste the following code:

   Function YearsBetween(StartDate As Date, EndDate As Date) As Integer
       YearsBetween = Year(EndDate) - Year(StartDate) - (Format(EndDate, "mmdd") < Format(StartDate, "mmdd"))
   End Function
   

4. Close the editor and return to your Excel sheet.
5. In cell C5, use your custom function:

   =YearsBetween(A1, B1)
   

This creates a user-defined function that calculates the years between two dates exactly how you want.

Important Notes:

<p class="pro-note">💡 Pro Tip: VBA can be a powerful tool, but make sure to save your workbook as a macro-enabled file (.xlsm) to keep the function active!</p>
