Hello, Jennifer!
Not to worry! What you may be seeing is that there are no specific "Special Events" held during July and August, so there's nothing to post there. This would involve performers, concerts and unique events particular to a time of year, which doesn't apply to your time of stay in the parks.
What you might find more helpful is to go to each park's webpage (
I've embedded a link to Magic Kingdom Park's Calendar Page here) and click on "Calendar." This will give you information, on a daily basis, for each park you're visiting, including parade times, fireworks and park open / close.
Additional events may be added from time to time, such as Fantasmic! Dining Experiences, but there won't be "Special Events" added for the time period of your stay.
Please send me more specifics as to your itinerary and resort, so I can give you some tips for the Fourth of July celebrations which will take place during your stay! You are in for a TREAT!
