The date is also listed on a sign at Apple Park that was shared today on Twitter, but the sign does not offer up a specific time for the event.
According to our source, the Apple Park Visitor Center features a gift shop with Apple-branded items available for purchase, much like the store at One Infinite Loop, but it does not have a full Apple Store and will not stock devices like the iPhone X.
Prior to the November 17 grand opening, Apple is inviting Cupertino residents who live near the Apple Park campus to preview the Visitor Center on Thursday, November 16. Residents can visit Apple Park from 3:00 p.m. to 8:00 p.m., with a photo ID confirming a nearby address required for entry.
