MORE INFORMATION ================ Microsoft provides programming examples for illustration only, without warranty either expressed or implied, including, but not limited to, the implied warranties of merchantability and/or fitness for a particular purpose. This article assumes that you are familiar with the programming language being demonstrated and the tools used to create and debug procedures.

The DateValue() function converts a specified date, beginning with December 30, 1899, to a serial number. Syntax: DateValue(DateText$) Examples -------- x = DateValue("12/30/1899") ' returns 0 or zero x = DateValue("12/31/1899") ' returns 1 x = DateValue("12/5/1992") ' returns 33943 The Sgn() function is used to determine if the difference between two dates is a negative(date in the past) or positive(date in the future) number. Sub DayDiff() Dim sDate As String Dim intNumDays As Integer On Error GoTo errhandler ' Prompt for a date. sDate = InputBox$("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."
