To create the calendar, follow these steps.

Microsoft Excel 2003

  1. Create a new workbook.
  2. On the Tools menu, point to Macro, and then click Visual Basic Editor.
  3. On the Insert menu, click Module.
  4. Copy the Visual Basic for Applications code below into the module sheet.
  5. On the File menu, click "Close and Return to Microsoft Excel."
  6. Click the Sheet1 tab.
  7. On the Tools menu, point to Macro, and then click Macros.
  8. Click CalendarMaker, and then click Run to create the calendar.

Microsoft Excel 2007 and Excel 2010

  1. Create a new workbook.
  2. On the Developer ribbon, Click Visual Basic. 
  3. On the Insert menu, click Module.
  4. Copy the Visual Basic for Applications code below into the module sheet.
  5. On the File menu, click "Close and Return to Microsoft Excel."
  6. Click the Sheet1 tab.
  7. On the Developer ribbon, click Macros
  8. Click CalendarMaker, and then click Run to create the calendar.

NOTE: If the Developer Ribbon is not showing go to Excel Options and enable it. In Excel 2007 you will find it in the Popular menu and in Excel 2010 you will find it in the Customize Ribbon menu.

           & Chr(13) & "Spell the Month correctly" _
           & " (or use 3 letter abbreviation)" _
           & Chr(13) & "and 4 digits for the Year"
       MyInput = InputBox("Type in Month and year for Calendar")
       If MyInput = "" Then Exit Sub
       Resume
   End Sub
				
You can add other code to customize the calendar to meet your needs. Insert extra rows for entry on the screen for each day or resize the screen to see all of the calendar based on screen size and resolution.
