mentioned date and time functions to a worksheet cell means that Excel will format the cell
with its default Date format.
There are a number of other date-related and time-related functions that you can use to
perform calculations in your Excel VBA code. The two most useful functions are DateAdd and
DateDiff . DateAdd , as the name implies, lets you add a time period to a date or time. Yes, you
can add three days to a date with simple addition, as in the following procedure:
Public Sub AddDays()
Dim datFirst, datSecond As Date
datFirst = #1/9/2004#
datSecond = datFirst + 3
MsgBox ("The new date is: " & datSecond & ".")
End Sub
