SUMMARY

This article describes a function that you can use to find the date of the Monday prior to the current day.

This article assumes that you are familiar with Visual Basic for Applications and with creating Microsoft Access applications using the programming tools provided with Microsoft Access. For more information about Visual Basic for Applications, please refer to your version of the "Building Applications with Microsoft Access" manual.

NOTE: Visual Basic for Applications is called Access Basic in Microsoft Access versions 1.x and 2.0.

MORE INFORMATION

The following function determines Monday's date according to the following criteria:

  • If the current date is Tuesday through Sunday, it yields the prior Monday's date.
  • If the current day is Monday, it returns the current date.
  • If the date is Null or is not a valid date, it returns Null.

         Function GetMonDate(CurrentDate)
         If VarType(CurrentDate)<>7 then
           GetMonDate=Null
         Else
           Select Case WeekDay(CurrentDate)
             Case 1       ' Sunday
               GetMonDate=CurrentDate-6
             Case 2       ' Monday
               GetMonDate=CurrentDate
             Case 3 to 7  ' Tuesday..Saturday
               GetMonDate=CurrentDate-WeekDay(CurrentDate)+2
           End Select
         End If
        End Function
                            

To test the function, type the following line in the Debug window (or Immediate window in versions 1.x and 2.0), and then press ENTER:

Print GetMonDate(#4/30/93#)


Note that you receive the following result:
