Inserting A Monthly Calendar

I don't know of anything "basic" for a calendar. Any solution will require VBA as Excel does not have a built in calendar.

Do you want a SHEET that is a calendar that you can enter data into? (you can download one from Chip Pearson's site here: http://www.cpearson.com/excel/download.htm Choose Calendar from the list of available downloads and follow the instructions)

Do you want a calendar that 'pops up' when a specific cell is selected?[vba]
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
If Target.Cells.Count > 1 Then Exit Sub
' set the Range below to the cell you want to select to pop up the calendar
If Not Application.Intersect(Range("A1"), Target) Is Nothing Then
Calendar1.Left = Target.Left + Target.Width - Calendar1.Width
Calendar1.Top = Target.Top + Target.Height
Calendar1.Visible = True
' select Today's date in the Calendar
Calendar1.Value = Date
Else: Calendar1.Visible = False
End If
End Sub[/vba] Entered in the Worksheet project in the VBA Editor where you want it displayed (Today's date will be highlighted).

If desired: [vba]
Private Sub Calendar1_Click()
ActiveCell.Value = CDbl(Calendar1.Value)
ActiveCell.NumberFormat = "dd-mmm"
ActiveCell.Select
End Sub[/vba] will enter the selected date (by clicking on the calendar) into the target cell specified in the previous code as "Range".


Will one of these meet your needs?


More info, please.
