Hi Judy,
You can find the online park calendars by following these steps:-
1/ Visit the Walt Disney World website
2/ Click on PARKS
3/ Click on Magic Kingdom
4/ Click on Calendar (underneath Overview on the left hand side of the page)
5/ Select the proposed month of your visit by clicking on the drop down box next to View Month and selecting the month under consideration - for example January 2013 which you can see by clicking
HERE.
You can see the park hours for the other Disney Theme Parks and Water Parks by following these same steps but clicking on each individual Theme Park instead of selecting the Magic Kingdom.
The park calendars are normally available to view for the current month plus the following six months at all times and are updated at the beginning of each month. I would expect the park calendar for February 2013 to be available at the beginning of August 2012.
Wishing you a magical trip filled with memories which will last a lifetime!
