Hi Kishore,
You cannot see previous year data for current weekend date.
So one option is to choose either of the weekend date and month part as the base to show the data of current and previous years.
For example take 6/4 out of 6/4/2015 and show CY and PY data for the same date and month.
If you see your other fields you are showing only month number and quarter number but not the years. So similarly show the day number which is common for both the years.
Else choose the week numbers than week dates as Mahaboob suggested.
