Introduction:
Calculating the number of years between two dates can be useful for various purposes, such as determining someone’s age or calculating the duration of a project. Microsoft Excel offers several methods to perform these calculations, and in this article, we will discuss how to calculate years between dates in Excel effectively.
Method 1: Using the DATEDIF Function
The most straightforward method for calculating the number of years between two dates in Excel is using the DATEDIF function. The DATEDIF function calculates the difference between two dates using specified intervals.
Syntax:
DATEDIF(start_date, end_date, “interval”)
Example:
Assume that you have the following dates:
Start_date: A2 (01/01/2000)
End_date: B2 (12/31/2021)
Using DATEDIF to calculate the years between these dates:
=DATEDIF(A2, B2, “y”)
This formula will return 21 as the number of years between the two dates.
Method 2: Using YEARFRAC Function
Another method for calculating the number of years between two dates is by using the YEARFRAC function. The YEARFRAC function computes a decimal value representing a fraction of a year between two given dates.
Syntax:
YEARFRAC(start_date, end_date, [basis])
Example:
Using the previous example:
Start_date: A2 (01/01/2000)
End_date: B2 (12/31/2021)
Using YEARFRAC to compute the difference between these two dates:
=YEARFRAC(A2, B2)
This formula will return approximately 21.9973 as the decimal value representing years between provided dates. You can round this figure based on your requirements using standard rounding techniques in Excel.
Method 3: Subtraction and Division
In some cases, you might want to calculate the number of years between two dates manually. To do that, you can subtract one date from another and then divide by 365 or 365.25 (considering leap years).
Example:
Using the previously mentioned example:
Start_date: A2 (01/01/2000)
End_date: B2 (12/31/2021)
Manually calculating years between two dates:
=(B2-A2)/365.25
This formula will give you approximately 21.9973 as the decimal value of years between the two dates.
Conclusion:
Calculating years between dates in Excel is easily done using the DATEDIF function or YEARFRAC function or even simple subtraction and division method, depending on your need for precision. These methods allow you to derive insights from your data and make informed decisions.
