How to Calculate Age from Date of Birth in Google Sheets

Calculating age in Google Sheets can be a helpful tool when you need to quickly determine someone’s age based on their date of birth. In this post, we will cover how to calculate age using the date difference function in Google Sheets.

The date difference function has three parameters: start date, end date, and unit. The accepted units for this function are y (years), ym (whole months after subtracting years), and md (days after subtracting whole months). To calculate age in years, we will use the y unit.

To use the date difference function to calculate age in years, simply input the function `datedif(start_date, end_date, “y”)` into a cell in your Google Sheet. In this function, replace “start date” and “end date” with the appropriate cell references and ensure that “y” is in quotation marks.

To calculate age in months or days, use the units ym and md respectively. You can input the function `datedif(start_date, end_date, “ym”)` to calculate age in months and `datedif(start_date, end_date, “md”)` to calculate age in days.

To calculate age in years, months, and days in one formula, you will need to nest the date difference function using the “and” symbol. The formula for this would be `=DATEDIF(A2,B2,”Y”) & ” Years, ” & DATEDIF(A2,B2,”YM”) & ” Months, ” & DATEDIF(A2,B2,”MD”) & ” Days”`. In this formula, replace A2 and B2 with the appropriate cell references.

In conclusion, calculating age in Google Sheets is a simple process using the date difference function. By inputting the correct parameters and units, you can easily determine someone’s age based on their date of birth.
