Total worksheets based on Date

I've named all worksheets in a "dd-mmm-yyyy" format
there is a section in within every worksheet that I want to do a YTD total on.  The total should be the current sheet as well as all worksheets within the current year less than the date of the current worksheet. It's kinda hard to explain.
I've Attached a copy of my worksheet.  the area that needs to be YTD is in Orange.

Here is a working code for your problem. It should be pasted in ThisWorkbook section of VBA. When you run SumItAll, all values from C17 to S32 on all sheets with a valid date as a name will be set to $0.00.

Then each sheet with a valid date will be compared to the other and the appropriate values will be added one at a time. This is not the most effective way of doing this, so the calculation should not be done each time Excel does an automatic recalculation. Also, make sure that each person stays on the same column from sheet to sheet, as there are no checking of the names in row 3.

Finally, it's getting late, so I have not had time to debug this code thoroughly. Use it at your own risk and to control to see that the numbers really add up.
Sub SumItAll()
    Const NumbersOfDataRows = 16
    Const FirstSumRow = 17
    Const FirstSourceRow = 35
    Const FirstColumnToSum = 3
    Const LastColumnToSum = 19
    
    Dim CurrentSheet As Worksheet
    Dim DataSheet As Worksheet
    
    Dim CurrentDate As Date
    Dim DataDate As Date
    
    Dim ValidDate As Boolean
    
    Dim SplitDate As Variant
    
    For Each CurrentSheet In ThisWorkbook.Sheets
        ValidDate = SheetName2Date(CurrentSheet.Name, CurrentDate)
        If ValidDate Then
            'Zero the totals
            For r = 1 To NumbersOfDataRows
                For c = FirstColumnToSum To LastColumnToSum
                    CurrentSheet.Cells(r + FirstSumRow - 1, c).Value = 0
                Next c
            Next r
            
            For Each DataSheet In ThisWorkbook.Sheets
                ValidDate = SheetName2Date(DataSheet.Name, DataDate)
                If ValidDate Then
                    
                    'Dates on both sheets have been found valid
                    If (DataDate <= CurrentDate) And (DataDate >= DateSerial(Year(CurrentDate), 1, 1)) Then
                        'Date on DataSheet is within interesting range
                        For r = 1 To NumbersOfDataRows
                            For c = FirstColumnToSum To LastColumnToSum
                                CurrentSheet.Cells(r + FirstSumRow - 1, c).Value = _
                                CurrentSheet.Cells(r + FirstSumRow - 1, c).Value + _
                                DataSheet.Cells(r + FirstSourceRow - 1, c).Value
                            Next c
                        Next r
                        
                    End If
                End If
            Next DataSheet
        
        End If
    Next CurrentSheet
    
End Sub

You might consider using a user-defined function with a worksheet formula like:
=YTD(C35)

Put the following code in a regular module sheet:
Function YTD(CellToSum As Range) As Variant
Dim ws As Worksheet
Dim CurrentDate As Date
Application.Volatile
CurrentDate = CDate(CellToSum.Worksheet.Name)
If IsDate(CellToSum.Worksheet.Name) Then
    CurrentDate = CellToSum.Worksheet.Name
Else
    YTD = "#DATE!"
    Exit Function
End If
For Each ws In CellToSum.Worksheet.Parent.Worksheets
    If IsDate(ws.Name) Then
        If CDate(ws.Name) <= CurrentDate Then YTD = Application.Sum(YTD, ws.Range(CellToSum.Address))
    End If
Next
End Function

Open in new window


The attached workbook shows how it might work. See the formula in cell C17 on 6-Apr-2013 worksheet.

Mr. byundt,

what if I don't want to go for date based sum i.e. sum of all sheet cell excluding current sheet.

=YTD(C3) which calculate sum of all sheet excluding current sheet.

Cell Sum

Thanks
