Hide Columns automatically based on year month(YYYY-mm)

Dear all,

I'm new to this Macro programming. I was going through one of the report in which I have to first unhide Current and upcoimg month and then hide upcoming month. Example


2014-08 2014-09 2014-10 Total
ColA ColB Col C ColD ColE Col F ColG ColH Col I ColJ ColK ColL
# of Tkts # of Tkts linked # of KBs # of Tkts # of Tkts linked # of KBs # of Tkts # of Tkts linked # of KBs # of Tkts # of Tkts linked # of KBs

If I have to run a report for this week fortnight I unhide from Col D to Col L and input the data below D2,E2 and F2 and after completing the input of records hide Col G - Col L.

Do I have to Insert three columns every month or just hide and unhide of the columns can resolve the porblem.

Please help in resovling the query.
