Google Calendar is an online calendar application that allows users to schedule, manage, and share events and meetings. Integrated with Gmail and Google Meet, it offers automatic event creation from emails, reminders, smart scheduling, and collaborative calendars for teams. Users can access it via web or mobile, and sync across devices. Features include recurring events, color-coded calendars, guest invitations, timezone handling, and public calendar sharing. For organizations, it supports room/resource booking, shared availability, and integration with third-party scheduling tools.

Google Calendar is inaccessible in mainland China due to national internet restrictions affecting Google’s suite of services. Attempts to access the service or sync events via mobile or desktop apps fail without circumvention tools. This has a significant impact on international scheduling and integration with other Workspace tools like Gmail or Meet. Furthermore, calendar links embedded in emails or websites may not render properly for users in China. As a result, Chinese businesses and users turn to domestic alternatives like Tencent Calendar, WPS Calendar, and enterprise-oriented tools in DingTalk or Feishu. These services offer similar basic scheduling functions but lack global interoperability and some advanced AI scheduling features found in Google Calendar. Developers offering SaaS products or scheduling apps in China should avoid reliance on Google Calendar APIs and instead support integrations with regional calendars or custom event systems hosted locally.

The information regarding service availability in China is provided for general reference purposes only. Due to the dynamic nature of network conditions and regulatory environments, the actual accessibility of these services may vary over time and by location. Users are advised to verify the current status independently.
