While we do know that iOS 15 is coming on September 20, Apple has not specified what time of day it will be released. We can, however, make an educated guess as to when to release.
The most common time of day for Apple software releases is around 10:00 a.m. PT. In some parts of the world, that is the early morning hours of the next day, and Apple’s regional websites for some of those countries say the release date is September 21 rather than September 20.
Based on this information, it seems very likely that iOS 15 will actually be released around 10:00 a.m. PT on Monday, September 20. For the local time in your area, we’ve compiled this list covering some major time zone cities around the world:

Apple has occasionally released software updates closer to 1:00 p.m. PT, but that doesn’t match information from Apple’s India site, which specifies a September 20 launch. For this to be the case, a release would have to take place before 11:30 a.m. PT.
