To calculate age in Excel using an age calculator, you can use these formulas for different scenarios. For age on the last birthday, apply =DATEDIF(A2, B2, “Y”). If you need to determine age on the next birthday, use =DATEDIF(A2, B2, “Y”)+1. To find age in years and months, use =DATEDIF(A2, B2, “Y”) for years and =DATEDIF(A2, B2, “YM”) for months.
For calculating age in years and days, use =DATEDIF(A2, B2, “Y”) for years and =DATEDIF(A2, B2, “YD”) for days. To get age in years, months, and days, use =DATEDIF(A2, B2, “Y”) for years, =DATEDIF(A2, B2, “YM”) for months, and =DATEDIF(A2, B2, “MD”) for days.
