From the Motorola Website: ===================== Calendar works with Google Calendar web-based calendaring service for creating and managing events, meetings, and appointments. When you first set up your phone, you configured it to use an existing Google Account, or you created a new account. The first time you open the Calendar application on your phone, it displays any existing calendar events from your Google Account on the web. Calendar on the phone is optimized for the phone. There are some Calendar features (such as creating Calendars and inviting guests to events) that are only available in Calendar on the web. Be sure to visit Google Calendar on the web (http://calendar.google.com) to learn more about the features the web and phone versions share, and to learn about and use web-only features. To create an event: From the Applications Menu, touch Calendar Press Menu Touch New Event to open the Event details screen. You can also touch & hold a spot in Day, Week, or Month view to open a menu where you can touch New Event, to open the Event details screen with that day and time pre-entered. Add details about the event. You enter a name, time, and optional additional events about the event, just as you do in Google Calendar on the web. If you have more than one calendar, you can choose the calendar you want to add the event to. You can touch the plus button to add additional reminders Press Menu and touch Show extra options to add additional details about the event. Scroll to the bottom of the Event details screen and touch Done. The event is added to your calendar. To invite others to the event and configure additional details, open the event in Google Calendar on the web. To change your calendar view: From the Applications Menu, touch Calendar Press Menu Touch Agenda, Day, Week or Month Each view displays in the events in your calendar for a period of time. To view more information about an event in Agenda view, touch the event. To view more information about an event in Day or Week view, touch the event to open a quick view summary. Touch the quick view for even more information. To view the events of a day in Month view, touch a day. Note: Meetings can be accepted and rejected via the calendar application, not the email application.
