Update: iOS 16 is now rolling out to all eligible devices, though it may take a few minutes to show up for all users.
First announced in June at Apple's Worldwide Developers Conference, iOS 16 is launching today, September 12, 2022, in most countries around the world. Given a simultaneous worldwide release, some countries will not see a launch until the early hours of September 13.
While Apple hasn't officially announced what time iOS 16 will be released, we have a fairly good idea based on previous releases as Apple typically releases major operating system updates at around 10:00 a.m. Pacific Time. There have been a few exceptions to this schedule, but only on a very limited basis and usually in somewhat unusual circumstances that we aren't seeing for iOS 16.
Assuming the typical 10:00 a.m. Pacific launch time, iOS 16 will be available at approximately these times around the world:
- Honolulu, Hawaii — 7:00 a.m. HAST
- Anchorage, Alaska — 9:00 a.m. AKDT
- Cupertino, California — 10:00 a.m. PDT
- Phoenix, Arizona — 10:00 a.m. MST
- Vancouver, Canada — 10:00 a.m. PDT
- Denver, Colorado — 11:00 a.m. MDT
- Dallas, Texas — 12:00 noon CDT
- New York, New York — 1:00 p.m. EDT
- Toronto, Canada — 1:00 p.m. EDT
- Halifax, Canada — 2:00 p.m. ADT
- Rio de Janeiro, Brazil — 2:00 p.m. BRT

Note that iPadOS 16 will not be launching alongside iOS 16 today, an unusual separation in Apple's release schedule. In early August, Bloomberg reported that Apple was planning to delay the launch of iPadOS 16 until October, and Apple has since confirmed that iPadOS 16 will indeed be launched sometime in October.
