Pivot table month sort order

I have date Column named Month formatted as "02/11/2009". In a separate column I use a =text(cell,"MMM-YY") formula to get the dates into a month format so "02/11/2009" becomes "Feb-09" in the new column. However, when I create a pivot table, it sorts the "MMM-YY" alphabetically instead of chronologically,
How to sort it properly?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Rather converting to text, use a function to round the date to the end/beginning of the month:

End of month

Beginning of Month

The numerical parameter is the number of months to add to the date. Adding 0 months just rounds to the end of the month; -1 months rounds back to previous month end and then adding 1 to the result gives the first of the next month.

Format the result as "mmm-yy" and you will see the same result but the dates will then sort in order as expected.

Alternatively, I know there is a function, but not sure how to do it, where you can group data such as dates in a Pivot Table so that you still see only the one column per month rather than a column for each day of the month.

You then wouldn't need the extra column at all.

How to apply them? ..In source data column  or in pivot area?
 Is that used with  separate new column or existing one?

No just one of them depending whether you want the date rounded up or down.
