Formula for Yesterday
Name Manager, New Name. Yesterday =TODAY()-1. OK. Then, use =YESTERDAY in any cell. Tomorrow could be =TODAY()+1.

Try this code. The result starts from cell F2. Change it as required.
VBA Code:
``````Sub MissingDates()
Dim A
Dim T As Long, Ta As Long, X As Long, Y As Long

A = Range("A2").CurrentRegion.Offset(1, 0)
ReDim C(1 To 10 * UBound(A, 1), 1 To 3)
For T = 1 To UBound(A, 1) - 1
X = X + 1
C(X, 1) = A(T, 1): C(X, 2) = A(T, 2): C(X, 3) = A(T, 3)
If A(T, 1) = A(T + 1, 1) And A(T + 1, 2) > A(T, 2) + 1 Then
For Ta = A(T, 2) + 1 To A(T + 1, 2) - 1
X = X + 1: Y = Y + 1
C(X, 1) = A(T, 1): C(X, 2) = A(T, 2) + Y
Next Ta
End If
Y = 0
Next T
Range("F2").CurrentRegion.Clear
Range("F2").Resize(X, 3) = C

End Sub``````
