5 Ways To Calculate Years Between Dates In Excel

Intro

Discover 5 efficient ways to calculate years between dates in Excel, including using formulas like DATEDIF and YEARFRAC, and Excel functions like DATE and TEXT. Learn how to easily find the difference between dates, calculate age, and perform date arithmetic with step-by-step examples and expert tips.

When working with dates in Excel, it's common to need to calculate the number of years between two dates. This can be useful for a variety of purposes, such as calculating the age of an individual, determining the length of time between events, or analyzing trends over time. Fortunately, there are several ways to calculate years between dates in Excel, and we'll explore five different methods in this article.

Why is Calculating Years Between Dates Important?

Calculating years between dates is an essential skill in data analysis, particularly when working with datasets that involve time-based information. By calculating the number of years between dates, you can:

  • Determine the age of an individual or the length of time since an event occurred
  • Analyze trends over time, such as sales data or website traffic
  • Identify patterns or correlations between dates and other variables
  • Create age-based categorizations or groupings in your data

Method 1: Using the YEARFRAC Function

The YEARFRAC function in Excel calculates the fraction of a year between two dates. By multiplying the result by 12, you can calculate the number of months between the dates, and then divide by 12 to get the number of years.

Formula: =YEARFRAC(start_date, end_date)

Example: =YEARFRAC(A1, B1)

Assuming the start date is in cell A1 and the end date is in cell B1, this formula will return the fraction of a year between the two dates.

Method 2: Using the DATEDIF Function

The DATEDIF function in Excel calculates the difference between two dates in a specified interval, such as days, months, or years.

Formula: =DATEDIF(start_date, end_date, "y")

Example: =DATEDIF(A1, B1, "y")

Assuming the start date is in cell A1 and the end date is in cell B1, this formula will return the number of years between the two dates.

Method 3: Using the INT and YEAR Functions

This method involves using the INT function to extract the year from each date and then subtracting the start year from the end year.

Formula: =INT(YEAR(end_date)) - INT(YEAR(start_date))

Example: =INT(YEAR(B1)) - INT(YEAR(A1))

Assuming the start date is in cell A1 and the end date is in cell B1, this formula will return the number of years between the two dates.

Method 4: Using the DATE Function

This method involves using the DATE function to create a new date based on the year of the end date and the month and day of the start date. The difference between this new date and the start date is then calculated.

Formula: =DATE(YEAR(end_date), MONTH(start_date), DAY(start_date)) - start_date

Example: =DATE(YEAR(B1), MONTH(A1), DAY(A1)) - A1

Assuming the start date is in cell A1 and the end date is in cell B1, this formula will return the number of years between the two dates.

Method 5: Using the POWER and YEAR Functions

This method involves using the POWER function to raise the end year to the power of 1 and then subtracting the start year.

Formula: =POWER(YEAR(end_date), 1) - YEAR(start_date)

Example: =POWER(YEAR(B1), 1) - YEAR(A1)

Assuming the start date is in cell A1 and the end date is in cell B1, this formula will return the number of years between the two dates.
