Final answer:
To convert a birthdate to age in Excel, you can use the DATEDIF function. For example, if the birthdate is in cell A1, the formula would be: ' =DATEDIF(A1, TODAY(), "Y")' for years.
Step-by-step explanation:
In Excel, the DATEDIF function calculates the difference between two dates in various units, including years. The formula '=DATEDIF(A1, TODAY(), "Y")' subtracts the birthdate in cell A1 from the current date (TODAY()) and returns the result in years. The "Y" argument specifies the unit as years. This formula provides an accurate age calculation that updates automatically with the current date.
It's crucial to use the "Y" argument in the formula to specify that the desired unit is years. The dynamic nature of this approach ensures that the age calculation automatically adjusts as time progresses, always reflecting the current age based on the present date. This method is efficient for maintaining accurate age records, especially in scenarios where ages need to be continuously updated without manual intervention. Employing DATEDIF in Excel streamlines the process of converting birthdates to ages and facilitates the management of age-related data in spreadsheets.
By using the DATEDIF function in Excel, you can easily convert a birthdate to age. This method is dynamic, ensuring that the age automatically updates as the current date changes, making it a convenient and accurate way to track and display ages based on birthdates in your Excel spreadsheets.
