Here's When iOS 27 Rolls Out Today in Every Time Zone [Update: It's Out]

Update 10:04 a.m.: iOS 27 is rolling out now, though it may take a bit for all users to see it, so keep checking!

Apple is about to release ‌iOS 27‌, which will finally deliver more advanced Siri AI capabilities as well as a variety of other refinements, improvements, and new features to iPhones. It's Apple's biggest software update of the year, and Apple announced at Wednesday's iPhone event that it will be releasing ‌iOS 27‌ sometime today – Monday, September 14.

‌iOS 27‌ won't be the only release today, as macOS Golden Gate and other releases in the OS 27 family will also drop around the same time as ‌iOS 27‌.

Based on past releases, the update is likely to drop at around 10:00 a.m. Pacific Time/1:00 p.m. Eastern Time. Apple's own websites for countries around the world also suggest a 10:00 a.m. Pacific Time release, with Apple's site for India listing a September 14 launch while the company's pages for Singapore, Hong Kong, and others in that region list a September 15 release. That points to a narrow release window around 10:00 a.m. Pacific to line up with time zones where it will be after midnight in some of those countries.

To give iPhone users globally an idea of when ‌iOS 27‌ should become available as an over-the-air update, we've compiled the below list of time zone conversions for a number of countries. This list isn't exhaustive, so please verify the exact time for your specific location, and bear in mind that there could always be a delay as Apple prepares its servers for rollout.

Be Prepared to Wait

When ‌iOS 27‌ and iPadOS 27 become available as an over-the-air update, make sure your device is fully charged before you start the process over Wi-Fi, as it may take some time to complete. To check that the update is available, go to Settings ➝ General ➝ Software Update, and wait a moment for your device to contact Apple's servers. If you're in no rush, you can wait for ‌iOS 27‌ to be delivered to your iPhone when you next plug it into your computer.

On that note, a word of caution: During the initial rollout of major software updates like ‌iOS 27‌, Apple users may experience slower download speeds and sluggish performance when trying to update their devices. This is largely due to the high demand on Apple's servers, as millions of users worldwide attempt to download the update simultaneously.

The surge in traffic can overwhelm network capacity, leading to delays in downloading or installing the update. To avoid these potential issues, you may want to wait a day or two before installing the update, allowing server congestion to subside and ensuring a smoother upgrade experience.
