Calculating years between dates in Excel is a common task that can be accomplished using various formulas and functions. In this article, we will explore the different methods to calculate years between dates in Excel, including using the DATEDIF function, the YEARFRAC function, and simple arithmetic operations.
Understanding the Problem
When working with dates in Excel, it's often necessary to calculate the number of years between two dates. This can be useful in various scenarios, such as calculating the age of a person, the duration of a project, or the tenure of an employee. However, calculating years between dates can be tricky, especially when dealing with different date formats and leap years.
Method 1: Using the DATEDIF Function
The DATEDIF function is a built-in Excel function that calculates the difference between two dates in a specified interval, such as days, months, or years. The syntax for the DATEDIF function is:
DATEDIF(start_date, end_date, unit)
Where:
- start_date is the starting date
- end_date is the ending date
- unit is the interval to use (e.g., "D" for days, "M" for months, "Y" for years)
To calculate the number of years between two dates using the DATEDIF function, you can use the following formula:
=DATEDIF(A1, B1, "Y")
Assuming the start date is in cell A1 and the end date is in cell B1.
Example:
Start Date | End Date | Years Between |
---|---|---|
01/01/2010 | 01/01/2020 | 10 |
Method 2: Using the YEARFRAC Function
The YEARFRAC function is another built-in Excel function that calculates the fraction of a year between two dates. The syntax for the YEARFRAC function is:
YEARFRAC(start_date, end_date, [basis])
Where:
- start_date is the starting date
- end_date is the ending date
- basis is an optional argument that specifies the day count basis to use (e.g., 0 for the 30/360 day count basis)
To calculate the number of years between two dates using the YEARFRAC function, you can use the following formula:
=YEARFRAC(A1, B1)
Assuming the start date is in cell A1 and the end date is in cell B1.
Example:
Start Date | End Date | Years Between |
---|---|---|
01/01/2010 | 01/01/2020 | 10.00 |
Method 3: Using Simple Arithmetic Operations
You can also calculate the number of years between two dates using simple arithmetic operations. One way to do this is to subtract the start date from the end date and then divide by 365 (the number of days in a year).
=INT((B1-A1)/365)
Assuming the start date is in cell A1 and the end date is in cell B1.
Example:
Start Date | End Date | Years Between |
---|---|---|
01/01/2010 | 01/01/2020 | 10 |

Conclusion
Calculating years between dates in Excel can be accomplished using various formulas and functions, including the DATEDIF function, the YEARFRAC function, and simple arithmetic operations. Each method has its own strengths and weaknesses, and the choice of method depends on the specific requirements of the task. By understanding the different methods and formulas available, you can easily calculate years between dates in Excel and perform other date-related calculations with confidence.
