Fireworks are shown every night at Magic Kingdom, HS, and Epcot year round.

The only way you wouldn’t see it is if there’s a ticketed event going on that you don’t want to purchase, the park is rented out, or its a closed event for cast members. But all of those scenarios are usually announced months in advance so you’ll know far ahead of time.

Unless you see otherwise, you can plan for seeing fireworks nightly
