How to find the same day of a month in the table date values.

I have a table with date values for the next 10 years. Against each date there is a flat which will be updated if the date matches a requirement.

The Requirement is to find the same day of a month in all years in the table. e.g 2nd Sunday of October in current year and all the years stored in the table and update the flag to 1.

Currently I am using this:

UPDATE FILTERCALENDAR SET YEAR_WINDOW=1 WHERE c_date = NEXT_DAY( TO_DATE('OCT-2013','MON-YYYY'), 'SUNDAY') + (2-1)*7;

As this is only for the current year. Can anyone suggest how can that be achieve for every year saved in the database. Currently the database table have 10 years in it.

Can Any one help me please.
