Integration with Google Suite: Since Google Calendar is a part of Google's Suite of services, it seamlessly integrates with Gmail, Google Meet, Google Chat. With the integration, users can schedule meetings directly from their inbox, without having to shift to another platform.

Ease of Time Zone Management: Google Calendar has a useful feature which automatically adjusts the meeting time for the guests based on their location. This is crucial for scheduling meetings with participants located in different time zones.

Calendar Sharing and Permission Control: Being a cloud-based tool, Google Calendar allows for calendar sharing amongst a team where individuals can view each other's availability. Furthermore, it gives you the control to decide who can view, edit, or manage your calendar, providing a tiered access system.

Meeting Details and Attachments: Google Calendar allows for comprehensive detail addition to each event. Users can add not just the time and venue, but also a descriptive agenda, attachments from Google Drive, and even custom reminders.

Availability Visualisation: Google calendar provides visual cues of free and busy slots, so it makes it easier for teams to schedule meetings when all/most participants are available, thereby improving the efficiency of scheduling.

Limited integration with third-party apps: While Google Calendar does integrate with other Google Suite products, it may not be as seamlessly integrated with other applications or online tools that your organization might be using.

Limited customization: Google Calendar offers only limited options for customization. For example, you can't customize the interface to match your company branding, neither can you add personalized fields or tags to the calendar events.

Lack of advanced scheduling features: Compared to some dedicated scheduling tools, Google Calendar lacks advanced features such as automated meeting transcription, tracking of meeting attendance and duration, or complex rules for availability.

No built-in video conferencing tool: Though Google Calendar integrates with Google Meet, it requires separately launching the video conferencing tool, which can create additional steps and hassles during the meeting scheduling process.

Absence of time zone conversion: Especially for organizations with international teams, a lack of automatic time zone conversion can lead to scheduling confusion and miscommunication. Although you manually can specify a time zone for each event, the process isn't automated and could be easily overlooked when arranging meetings across different time zones.
