Hey there Chelsie,
Welcome to planDisney and thank you for your question! I'm happy to hear that you're hard at work planning your next visit to the Happiest Place on Earth!
I'll start by saying that the schedule for
nighttime spectaculars does fluctuate throughout the year due to local rules and regulations and is subject to change at any time due to things like inclement weather. However, from my experience, there have historically been nighttime spectacular options on most nights, but the versions of those shows with fireworks are usually relegated to the weekends except during peak seasons.
Having said that, the place for you to get the definitive answer will be on the
Hours & Events calendar, where you can filter for the dates of your visit and the areas of the Disneyland Resort that you're interested to see the schedule for. I'll note that this schedule is released about six weeks out from the current date so you will need to wait another few weeks before the dates of your trip are available.
In the meantime, make sure to also check out the
Disney Parks Blog for additional news on all the fun things happening at the Happiest Place on Earth during your visit!
Thanks again for your question, Chelsie, and have a great trip!
Have a Magical Day,
Greg
