Code to be used for all the ranges in the column

[Tharabai]

I have used the below code to generate the dates within the date range (H3:I3)

Sub GenerateDates1()
Dim FirstDate As Date
Dim LastDate As Date
Dim NextDate As Date

FirstDate = Range("H3").Value
LastDate = Range("I3").Value

NextDate = FirstDate
Range("H4").Select

Do Until NextDate >= LastDate
NextDate = DateAdd("d", NextDate, 1)
    ActiveCell.Value = NextDate
    ActiveCell.Offset(1, 0).Select
 
Loop
End Sub

Can someone help me. I need to check all the date range in the column H and I.

Very Urgent… very grateful if someone can provide me the coding.
