Changing a birthday to age in Google Sheets entails using specific formulas. This guide will walk you through the process step-by-step, ensuring accurate results.

You'll also learn key tips to streamline your workflow in Google Sheets. However, we’ll also explore why Sourcetable is a better alternative to using Google Sheets.

## Google Sheets: How to Change Birthday to Age

### Using DATEDIF Function

To convert a birthday to age in Google Sheets, use the DATEDIF function. This function calculates the number of days, months, or years between two dates.

The basic syntax to calculate age in years is:

=DATEDIF(start_date, end_date, "Y")

Replace start_date with the cell containing the date of birth (DOB). Use the TODAY() function as the end_date to get the current date. For example:

=DATEDIF(A1, TODAY(), "Y")

This formula will return the age in full years for the DOB in cell A1.

### Using YEARFRAC Function

The YEARFRAC function calculates the fraction of a year between two dates. Use this function if you need a decimal representation of age. The syntax is:

=YEARFRAC(start_date, end_date)

Similar to DATEDIF, use the TODAY() function for the current date:

=YEARFRAC(A1, TODAY())

This formula returns the age as a decimal fraction.

### Calculating Detailed Age

Combine DATEDIF with concatenation to create a detailed age statement in years, months, and days. For example:

=DATEDIF(A1, TODAY(), "Y") & " Years, " & DATEDIF(A1, TODAY(), "YM") & " Months, " & DATEDIF(A1, TODAY(), "MD") & " Days"

This formula provides a more comprehensive age calculation.

### Calculating Age Across Multiple Rows

Use ARRAYFORMULA with DATEDIF to calculate age for multiple rows at once. Here is an example formula:

=ArrayFormula(DATEDIF(A1:A5, TODAY(), "Y") & " Years, " & DATEDIF(A1:A5, TODAY(), "YM") & " Months, " & DATEDIF(A1:A5, TODAY(), "MD") & " Days")

This formula calculates and displays the age for each DOB listed in cells A1 through A5.

### Automate Age Calculation
