Numbering every event which was splited from range to separate line - vba

Question

I found a VBA code online which does the hardest part of splitting absences data from ranges to separate line for each day. But one thing I cannot figure out how to do it is how to assign a number to each day that was requested. Could anyone help me? For better understanding see screenshot. Greatly appreciated!
Yellow and Green coloured lines separates events. Orange is the thing I am trying to accomplish. Absences
Sub One_Day_Per_Row()
Dim a, b
Dim rws As Long, sr As Long, i As Long, j As Long, k As Long, r As Long
a = Range("A2", Range("A" & Rows.Count).End(xlUp)).Resize(, 6).Value
rws = UBound(a, 1)
For r = 1 To rws
a(r, 6) = a(r, 5) - a(r, 4) + 1
k = k + a(r, 6)
Next r
If k < Rows.Count Then
ReDim b(1 To k, 1 To 4)
sr = 1
For r = 1 To rws
For i = 0 To a(r, 6) - 1
For j = 1 To 3
b(sr + i, j) = a(r, j)
Next j
b(sr + i, 4) = a(r, 4) + i
Next i
sr = sr + a(r, 6)
Next r
Range("G2").Resize(k, 4).Value = b
Range("G1:J1").Value = Array("emp number", "emp name", "absence code", "date")
Else
MsgBox "Too many rows"
End If
End Sub

Something like this should work:
Sub Tester()
Dim data, rw As Long, ws As Worksheet, dStart, dEnd, d, n As Long
Dim cOut As Range
Set ws = ActiveSheet 'or whatever
'read the data
data = ws.Range("A2:E" & ws.Cells(Rows.Count, "A").End(xlUp).Row).Value
Set cOut = ws.Range("G2") 'cell to begin output
For rw = 1 To UBound(data, 1)
dStart = data(rw, 4) 'start date
dEnd = data(rw, 5) 'end date
n = 1 'reset counter
For d = dStart To dEnd 'loop date range
cOut.Resize(1, 3).Value = Array(data(rw, 1), data(rw, 2), data(rw, 3))
cOut.Offset(0, 3).Value = d
cOut.Offset(0, 4).Value = n
n = n + 1
Set cOut = cOut.Offset(1, 0) 'next output row
Next d
Next rw
End Sub
