Apple's tagline for the event is "Wonderlust," a play on the word wanderlust. The September 12 event will take place at 10:00 a.m. Pacific Time.

Apple began using unique Twitter "like" animations to promote its events three years ago, with the first occasion being for 2020's September "Time Flies" event.

We can expect to see four new iPhones, two, or possibly three, new Apple Watches and perhaps AirPods fourth-generation go on sale next month. Before the release comes the event announcement ...

Twitter said the animation is part of an ad product the company is testing, called Branded Likes. The Apple Event animation will be live until 11:59 p.m. PT on Tuesday.

Other than a pretty, multicolored glowing logo, and the event’s date and time–September 9th at 10 a.m. Pacific Time–Apple revealed little about the upcoming occasion.
