Shifting columns in a workbook

Hello Experts,

I have a workbook with 12 sheets where Column A is Blank column B is details and column C to column N I have months (Jan’13, Feb’13,Mar’13…….) Column O has Year to Date Total 2013. In Column P to AA I have Jan’14 through Dec’14 and Column AB has Year to Date column.
Structure/Layout of all the worksheets is same

What I want to achieve is:

For each worksheet in the workbook place Months next to each other so that columns show:
Column C: Jan’13
Column D: Jan’14
Column E: Feb’13
Column F: Feb’14
.
.
.
Column AA: YTD 2013
Column AB: YTD 2014

Attached, is a workbook showing how columns currently look
