How to Calculate Chronological Age in Google Sheets
Using DATEDIF Function
The DATEDIF function is essential for computing age based on a birthdate in Google Sheets. This function requires three parameters: the start date (DOB), the end date (usually the current date using TODAY()), and the unit of measurement (years, months, or days). To calculate age in years using DATEDIF, the syntax is '=DATEDIF(start_date, TODAY(), "Y")'.
Using YEARFRAC Function
Alternatively, the YEARFRAC function provides a simpler method, particularly for calculating just the fraction of a year between two dates. This function is beneficial for determining age as it calculates the years more precisely. The typical formula to compute age using YEARFRAC would be '=YEARFRAC(DOB, TODAY())'.
Advanced Calculations
For a more detailed age calculation, such as including years, months, and days, you can employ DATEDIF with concatenation. Additionally, to compute age across multiple rows with either DATEDIF or YEARFRAC, incorporate the ARRAYFORMULA function, enabling the formula to fill down automatically across other cells.
These functions offer robust solutions for anyone needing to manage and analyze age data effectively within Google Sheets, making them indispensable tools in both personal and professional settings.
How to Calculate Chronological Age in Google Sheets
Calculating chronological age in Google Sheets is streamlined with the DATEDIF and TODAY() functions. This method ensures accuracy in reflecting the total number of years from a given date of birth (DOB) to today's date.
Using DATEDIF and TODAY()
To begin, the =DATEDIF(start_date, end_date, "Y") formula is crucial, where start_date is the DOB and end_date is the current date retrieved by =TODAY(). For a practical example, entering =DATEDIF(A1, TODAY(), "Y") in a cell will return the age in complete years for the DOB located in cell A1.
Detailed Age Breakdown
For a detailed age statement that includes years, months, and days, combine the DATEDIF function with concatenation: =DATEDIF(A1, TODAY(), "Y") & " Years " & DATEDIF(A1, TODAY(), "YM") & " Months & " & DATEDIF(A1, TODAY(), "MD") & " Days". This formula provides a comprehensive age calculation showcasing years, months, and days.
Calculating Age Across Multiple Rows
When dealing with multiple data entries, the ARRAYFORMULA function can be implemented to calculate ages for a range of rows simultaneously. Use the formula: =ArrayFormula(DATEDIF(A1:A5, TODAY(), "Y") & " Years " & DATEDIF(A1:A5, TODAY(), "YM") & " Months & " & DATEDIF(A1:A5, TODAY(), "MD") & " Days"). This method efficiently processes each DOB from A1 to A5, returning the age in years, months, and days for each entry.
This approach to calculating age in Google Sheets not only enhances productivity but also maintains accuracy, making it invaluable for personal and professional use.

Calculating Chronological Age in Google Sheets
Example 1: Basic Age Calculation
To calculate chronological age simply, subtract the birth date from the current date. Use the formula =DATEDIF(A2, TODAY(), "Y") where A2 holds the birthdate. This formula provides age in complete years.
Example 2: Including Months and Days
To include months and days in the age calculation, use the extended formula =DATEDIF(A2, TODAY(), "Y") & " Years, " & DATEDIF(A2, TODAY(), "YM") & " Months, " & DATEDIF(A2, TODAY(), "MD") & " Days". This breaks down the age into years, months, and days for a detailed view.
Example 3: Age on a Specific Date
If you need to find someone's age on a specific past or future date, replace TODAY() with a specific date in the formula. For instance, =DATEDIF(A2, "2023-12-31", "Y") calculates the age on December 31, 2023.
Example 4: Age Calculation for a List
For calculating ages for a list of people, input their birthdates in column A, then drag the fill handle down on the cell containing your chosen age calculation formula to apply it to all entries. This efficient method ensures quick calculations for multiple data entries.

Frequently Asked Questions
How do I calculate chronological age in years using Google Sheets?
To calculate chronological age in years from a date of birth in Google Sheets, use the DATEDIF function with TODAY() as the end date. The basic formula is '=DATEDIF(A1, TODAY(), "Y")', where A1 is the cell containing the date of birth.
Can I calculate detailed age including years, months, and days in Google Sheets?
Yes, you can calculate a detailed age statement in Google Sheets by using the DATEDIF function with concatenation. The formula is '=DATEDIF(A1, TODAY(), "Y") & " Years " & DATEDIF(A1, TODAY(), "YM") & " Months & " & DATEDIF(A1, TODAY(), "MD") & " Days"', where A1 is the cell containing the date of birth.
How to use the YEARFRAC function to calculate age in Google Sheets?
