At the WWDC26 event, Apple unveiled the iOS 27 system, which now includes built-in support for holiday and compensatory workday alarms in mainland China. This enhancement effectively eliminates the problem of iPhone alarms not functioning correctly on compensatory workdays. The Clock app in iOS 27 is now capable of directly identifying Chinese public holidays and compensatory workday schedules. When setting alarms, users can now choose a new option labeled "Workdays (Including Compensatory Workdays)," which allows for a combination of settings for regular workdays, compensatory workdays, and custom cycles. Once configured by the user, the system will automatically manage the alarm status: alarms will sound punctually on weekdays that are compensatory workdays, while remaining silent on public holidays or regular days off. This update specifically targets a common frustration among Chinese users, prompting widespread discussion.
