Hi there Esmeralda,
Welcome to planDisney and thanks so much for your question! I love visiting during the
Halloween season with my family - so I'm happy to hear you're planning a trip during this spooky season!
Ultimately, the best and most authoritative answer to your question will be through the
Hours & Events Calendar on the Disneyland Resort website. This is the official planned schedule for the parks and includes a few toggles at the top of the page including a date selector, park selector, and a toggle between a 1- and 5-day view.
This calendar is available about six weeks out from the current date, so it's not currently available for early October quite yet. From what I've seen in previous years, the schedule for
Fantasmic! and
fireworks looks a bit different during the Halloween and Christmas seasons. However, you can typically spot the pattern of the schedule once the first week or two of that season shows up on the Hours & Events Calendar.
For example, if you check the Hours & Events Calendar around the end of next week, it should show through around the 27th or 28th of August (depending on when you look at the page). The Halloween season kicks off on August 21, so you can check the calendar page for how the nighttime spectaculars are handled that first weekend to get a sense of what to expect for the rest of the season.
Then, I'd still recommend checking back in around August 23-24 as the schedule for October 4 should be published by then and you can get a better confirmation of what to expect on the day of your visit! One other caveat to note is that the calendar is the currently planned schedule but it is subject to change and shows like Fantasmic! and fireworks are very dependent on how the weather is that day. Keep an eye on the
Disneyland app the day of your visit to confirm those details!
Thanks again for your question, Esmeralda! I hope you have fun on your trip this fall to the Happiest Place on Earth.
Have a Magical Day,
Greg
