Sheet: Update

 |  | I would like to link this sheet with the Input_Data sheet and update colum A dates, accordingly. Column B, will be the same throughout the years and will always start with MON and ends with FRIDAY. For example, if user changes the year to 2014, the cell A6 should be blank as April 2012 1st working day is Tuesday and so on.
