Apple will hold its biggest event of the year in Cupertino, California on Wednesday, Sept. 9. The keynote is just the first part of a series of events which will culminate with the new products including the iPhone 18 Pro going on sale. There’s a lot happening, but we’ve got your back. This is the latest on what’s happening when so you can set your calendar.

iPhone 18 Pro: Launch Event At 10 a.m. Pacific, Wednesday, Sept. 9

The keynote that will see the launch of three iPhones, two Apple Watches and perhaps new AirPods will take place at Apple’s HQ.

The Steve Jobs Theater will be the venue and on Sept. 9, we’ll finally get to see Apple’s new products. The expectation is that the iPhone 18 Pro, iPhone 18 Pro Max and the first foldable iPhone will be unveiled alongside the Apple Watch Series 12 , Apple Watch Ultra 4 and possibly new AirPods.

That’s the latest list of products, and we’ll learn the answers to a bunch of questions: what will the foldable be called (and it may not be what you’re expecting ), what colors will the new iPhones be, will the foldable be on time and, crucially, how much will the new handsets cost?

The event starts at 10 a.m. Pacific, 1 p.m. Eastern and 6 p.m. BST (that’s British Summer Time in the U.K.). About 90 minutes later, the event, which will be introduced for the first time by Apple’s new CEO John Ternus, will have revealed everything.

iPhone 18 Pro: Pre-Orders Begin At 12 a.m. Saturday, Sept. 12

The next big event in the calendar is the opening of pre-orders, and it looks like this year that will happen a few hours later than usual.

Pre-orders routinely begin on the Friday after the keynote, at 5 a.m. Pacific, but things are going to be different this year. Just as the keynote was bumped from its routine Tuesday slot because Labor Day falls on Monday, Sept. 7, and Apple never holds an event on the day after Labor Day, so the pre-order schedule has changed.

The reason isn’t hard to see: Friday is Sept. 11, and not just any Sept. 11 but the 25th anniversary of the 2001 terrorist attack. So, out of respect, Apple is avoiding the date.

But only just. Instead of opening pre-orders at 5 a.m., it’s predicted to do so in the first seconds of Saturday, Sept. 12, that is, at 12 midnight Pacific. This works out to 3 a.m. Eastern, 8 a.m. U.K.

iPhone 18 Pro: On-Sale Date Friday, Sept. 18

Of all the dates in the calendar, this is the most certain prediction, although there’s still the question of whether the foldable will arrive at the same time.

The on-sale date for flagship iPhones is always on the Friday in the week after the keynote, which means Friday, Sept. 18. That looks certain to be the case this year, though the foldable phone could be later. This date will be revealed at the keynote.
