How Can We calculate our age in Excel ?
1️⃣ Basic Age in Years
If your birthdate is in cell A1:
excelCopyEdit=DATEDIF(A1, TODAY(), "Y")
"Y"gives the number of complete years.
2️⃣ Age in Years, Months, and Days
excelCopyEdit=DATEDIF(A1, TODAY(), "Y") & " Years, " & DATEDIF(A1, TODAY(), "YM") & " Months, " & DATEDIF(A1, TODAY(), "MD") & " Days"
"YM"= months after the last complete year."MD"= days after the last complete month.
3️⃣ Age in Decimal Years
excelCopyEdit=YEARFRAC(A1, TODAY())
- Gives a decimal number like 25.67 years.
4️⃣ Age in Months
excelCopyEdit=DATEDIF(A1, TODAY(), "M")
- Counts total full months since birth.
5️⃣ Age in Days
excelCopyEdit=TODAY() - A1
- Just subtracts dates to get days lived.
