Summary of the opening times of iOS 15 and iPadOS 15 upgrades in major cities in the world’s time zones

As Apple announced at the California Call event on September 14, the public release of iOS 15 will be on Monday, September 20. iPadOS 15, watchOS 8 and tvOS 15 will arrive on the same day, and the release date of macOS 12 Monterey has not yet been announced. Although we know that iOS 15 will arrive on September 20, Apple did not specify on which day it will be released. However, we can make an educated guess about the release time.

The most frequent time for Apple software releases is around 10 a.m. Pacific time. In some parts of the world, this is equivalent to the early morning of the next day, and Apple’s regional websites in some of these countries list the release date as September 21 instead of September 20.

Based on this information, iOS 15 is likely to be released at around 10 am Pacific time (Monday), September 20. Regarding the local time in your area, we have compiled a list covering major cities in most time zones in the world.

Apple sometimes releases software updates close to 1 pm Pacific time, but this is inconsistent with the information on Apple’s India website, which is designated to be released on September 20, so the release time needs to be determined before 11:30 am Pacific time.
