The schedule is going to vary depending upon the days of your particular trip. The only way to know for certain is to visit the Disney World web site at:

Bear in mind that the hours and scheduled events are subject to change right up to the actual dates of your trip, so you'll have to double-check when you arrive.
Generally speaking, the afternoon parades at Magic Kingdom, Disney Studios and Animal Kingdom will occur each afternoon, weather permitting. Illuminations fireworks are a nightly event at EPCOT. Fantasmic will play once or twice a night at Disney Studios. Magic Kingdom has Fire in the Sky (fireworks) and Spectromagic (parade) as its nighttime activities, but these two are often scheduled only when crowds are expected to be on the higher side.
