The following Visual Basic for Applications sample macro prompts for a date in the mm/dd/yy format, and returns the number of days between the current date and the specified date.

The DateValue function converts a specified date, beginning with December 30, 1899, to a serial number.

Syntax: DateValue(DateText$)

Examples
  x = DateValue("12/30/1899")  ' returns 0 or zero x = DateValue("12/31/1899") ' returns 1 x = DateValue("12/5/1992")  ' returns 33943 The Sgn function is used to determine if the difference between two dates is negative or positive number. A negative value indicates a date in the past, while a positive value indicates a date in the future. Sub DayDiff Dim sDate As String Dim intNumDays As Integer On Error GoTo errhandler ' Prompt for a date. sDate = InputBox$("Enter a date in the mm/dd/yy format") ' Get difference between dates. intNumDays = CInt(DateValue(sDate) - Now) ' Determine if difference is past or future. If Sgn(intNumDays) = 1 Then MsgBox "Days between " + sDate + " and today :" + CStr(intNumDays) Else MsgBox "The date " + sDate + " was" + CStr(Abs(intNumDays)) _ + " day(s) ago." End If errhandler: If Err > 0 Then MsgBox "Please enter a valid date."
