Google Calendar settings allow you to customize the way that your calendar works and looks. Some of the key settings that you can change include:

• General: This section allows you to change the language and time zone, as well as the way that events and reminders are displayed.

• Calendar: This section allows you to add, edit, and delete calendars, as well as change their settings, including the calendar color and notifications.

• Event settings: This section allows you to control the default settings for new events, such as the default duration and whether events automatically show as busy or free.

• Notifications: This section allows you to control the way that you receive notifications for events and reminders, including the type of notification (email, pop-up, or SMS), the time before an event, and the notification sound.

• Integrations: This section allows you to connect Google Calendar to other Google services, such as Google Drive and Google Maps, as well as to other non-Google services.

To access the Google Calendar settings, click on the gear icon in the top right corner of the screen and select "Settings" from the drop-down menu. From there, you can navigate to the different sections and make changes as needed. You can also adjust the settings for individual calendars as needed.
