Hi Michele,
As of now, the specific times of those events for
Star Wars Weekends haven't been released. However, you can explore previous Event Guides from past years to use as a possible guide to predict this year's time. If you visit www.allearsnet.com and do a search for
Star Wars Weekends, the results should lead you to copies of them. Just keep in mind the times may change, but it at least gives you a picture of when the events were held to make a tentative plan.
I'd also begin visiting the
Disney Parks Blog regularly since it will likely begin sharing more news about Star Wars Weekends, too, as the dates draw closer.
Have an great trip and enjoy all things Star Wars!
