Every year, Apple needs to whip up something exciting if it wants to get people hyped about the next iPhone. The same holds true especially for this year.

With iPhone sales falling 12% in the fiscal third quarter, profits expected to dip to $9.6 billion and more people trading in their iPhones for Androids, the company needs to make sure its iPhone 11, 11R and 11 Max (or whatever they'll be called) will be compelling enough to draw new customers or keep current customers updating.

So when will Apple officially announce the 2019 iPhones? The company hasn't sent out invitations to any iPhone events yet, but based on previous years, I predict Apple will unveil the next iPhones on Tuesday, Sept. 10.

Keep in mind this is just an educated guess, and we have no confirmation from Apple itself if this date is correct (Apple didn't immediately reply to a request to comment.) However, there are a few reasons why this is the likeliest date.

For the past seven years Apple has announced iPhones either in the same week as Labor Day, which is on the first Monday in September, or the following week. In the past, if the US holiday occurred on Sept. 3 or earlier, Apple announced its iPhone the following week. When Labor Day landed on the Sept. 5 or later, as it did in 2015 and 2016, Apple announced the iPhone the following Wednesday (two days after Labor Day). Peep the chart below to see what I mean:

APPLE IPHONE RELEASE AND ANNOUNCEMENT DATES (2012-2018)

This year, Labor Day is on Monday, Sept. 2. Keeping with the pattern, Apple would announce its new iPhones the following Tuesday or Wednesday: Sept. 10 or Sept. 11. Either date fits the pattern, but since the news cycle on Sept. 11 is best avoided for obvious reasons, I'd go with Sept. 10 as the safer bet. I also predict preorders will kick off that Friday, Sept. 13.

The date also aligns with the expected in-store release and shipping dates too, which I expect to both fall on Friday, Sept. 20. For the last seven years, you could purchase the regular flagship iPhones on a Friday, around the third week of September, about a week and a half after Apple makes its announcements. Specialty iPhones, like the iPhone XR, iPhone X and iPhone SE shipped out on their own timelines. Because the iPhone XR was available in October, there's a chance the iPhone 11R will be in users' hands in October too.

There you have it. I believe Apple will announce the new iPhone 11s on Sept. 10, with preorders on Sept. 13 and shipping starting Sept. 20. Again, without Apple's confirmation these are just predictions, but we'll find out soon enough if I'm correct.
