Excel calculates age accurate to a few years of age a few months

First, the following conditions are met

1 years old or older

month of January or more,

Less than a month to write days.

Second, the macro code

Function Getdatediff (STARTD, ENDD)

Dim y%, m%, d%

If STARTD > Endd or Not IsDate (STARTD) or not IsDate (endd) Then Getdatediff = "Data Error"

y = DateDiff ("yyyy", STARTD, ENDD)

If DateSerial (ENDD), Month (STARTD), Day (STARTD)) > Endd Then

y = y-1

If y >= 1 Then GoTo 100

m = 12-month (STARTD) + Month (ENDD)

Else

m = Month (endd)-Month (STARTD)

End If

If Day (ENDD) >= Day (STARTD) Or Day (ENDD) = Day (DateSerial (year (ENDD), Month (ENDD) + 1, 0)) Then

If Day (ENDD) >= Day (STARTD) Then d = Day (ENDD)-Day (STARTD)

If Day (ENDD) < Day (STARTD) and day (ENDD) = Day (DateSerial (ENDD), Month (ENDD) + 1, 0) Then d = Day (DateSerial (Ye AR (STARTD), Month (STARTD) + 1, 0))-Day (STARTD)

Else

m = m-1

D = Day (DateSerial (STARTD), Month (STARTD) + 1, 0))-day (STARTD) + Day (ENDD)

End If

If m >= 1 Then d = 0

100:getdatediff = IIf (Y > 0, Y & "old", IIf (M > 0, M & "month", D & "Day"))

End Function

Sub get Month Day ()

Dim arr1, ARR2 ()

arr = Sheet1.range ("A2:b" & Sheet1.range ("A65536"). End (Xlup). Row)

ReDim arr2 (1 to UBound (arr), 1 to 1)

For i = 1 to UBound (arr)

ARR2 (i, 1) = Getdatediff (arr (i, 1), arr (I, 2))

Next I

Sheet1.range ("C2:c" & Sheet1.range ("A65536"). End (Xlup). Row) = arr2

End Sub

The code above is a macro code that is used in a module.
