You can also choose to send the vCalendar in a multimedia message.

About the Calendar widget
There’s a Calendar widget available that you can add to your Home
screen, and it comes in different calendar views. Tapping a day or
event on the widget brings you to the Calendar application.
To find out how you can add a widget, see “Personalizing your Home
screen with widgets” in the Personalizing chapter.
