Hey there Hussein,
Welcome back to planDisney and thank you for your question! It sounds like you might be headed to the Happiest Place on Earth to ring in the new year next week - how fun!
As you mentioned, there will be fireworks at 9:00 PM on December 31st and then at 12:00 AM on January 1st. When looking at the
Hours & Events Calendar for those dates, it looks like the specific show that will be featured is called "New Year's Eve Fantasy in the Sky Fireworks Spectacular."
While there isn't currently a separate page detailing more about this show, it sounds like it will be likely be similar to previous New Year's Eve fireworks spectaculars and should be absolutely incredible!
My suggestion would be to keep an eye out when you arrive to the parks on December 31st especially in the daily guidebooks near the entry gates and within the
Disneyland Resort mobile app for more information on any other special themed entertainment and opportunities that will be available that day. Additionally, the Holiday season will still be in full swing so make sure to check out the
foodie guide on the Disney Parks Blog if you haven't already!
Thanks again for your question, Hussein! I hope you have a great time on your upcoming park visit and that you have a happy new year!
Have a Magical Day,
Greg
