Introduction:
Calculating age in Excel can be a useful tool, particularly when analyzing or categorizing data based on a person’s age. In this article, we will walk you through the process of calculating age in Excel using the DD/MM/YYYY format.
Step 1: Preparing the data
To calculate age in Excel, you need two dates: the person’s date of birth and the date you want to calculate their age as of (usually the current date). Ensure that these dates are positioned next to each other in separate columns. For example, if column A contains the names of individuals, column B would hold their date of birth, and column C would have today’s date.
Step 2: Calculating age using DATEDIF function
Microsoft Excel doesn’t have a dedicated function for calculating age; however, you can use the DATEDIF function to achieve this. The syntax for DATEDIF is as follows:
=DATEDIF(Start_date, End_date, Unit)
For our purposes:
– Start_date: Date of birth (use cell reference)
– End_date: The date you want to calculate the age as of (use cell reference)
– Unit: “Y” for years
Assuming that your data is prepared as mentioned above, enter the following formula into an empty cell adjacent to a person’s birthdate:
=DATEDIF(B2,C2,”Y”)
This formula calculates the number of complete years between the two dates but doesn’t display months and days.
Step 3: Extracting months and days
In order to extract months and days in addition to years, use a modified version of DATEDIF:
=DATEDIF(B2,C2,”Y”) & ” Years, ” & (DATEDIF(B2,C2,”YM”)) & ” Months, ” & (DATEDIF(B2,C2,”MD”)) & ” Days”
This formula calculates the age in years, months, and days.
Step 4: Applying the formula to all data
To apply the formula to all individuals in your dataset, simply click on the cell containing the formula, and then use the handle (the small square located on the bottom-right corner of a selected cell) to drag it down to other rows.
Step 5: Formatting
For a cleaner look, apply appropriate formatting to the calculated ages. Select the cells with the results of your formulas and find the formatting options under ‘Home,’ or simply press Ctrl + 1 to open the ‘Format Cells’ dialog box. From there, you can choose a custom format or create your own.
Conclusion:
Calculating age in Excel using the DD/MM/YYYY format is a straightforward process that can provide valuable insights into your data. Once you have mastered this process, you’ll be able to efficiently analyze data based on individuals’ ages and make better-informed decisions.
