Hey there Lanette,
Welcome to planDisney and thank you so much for stopping by with your question!
My preferred place to find things like theme park hours, entertainment schedules, and more for all areas of the Disneyland Resort is the
Daily Events Schedule page. When you visit this page, you'll see a date selector in the top left corner, clickable buttons for different areas of the resort (you can select more than 1!) and a toggle in the top right for a Day View or a 5-Day View.
One thing to note is that the official schedule is available about six weeks out from the current date, so if you're hoping to see this information for May 12, then you'll want to wait until March 31 or later for it to be made available.
May will be a great time to be in the parks as you'll be visiting in the midst of the
Disneyland Resort 70th Anniversary as well as the
Disney California Adventure Park 25th Anniversary! Keep an eye on the
Disney Parks Blog for more details on all the fun extras you'll get to check out on your upcoming trip.
Thanks again for stopping by planDisney, Lanette! I hope you have a wonderful visit to the Happiest Place on Earth.
Have a Magical Day,
Greg
