Overview

This code snippet demonstrates how to use the Calendar Service API for Web Runtime (introduced in S60 5th Edition) to add and delete calendars.

To obtain access to a service object for the Calendar Service API, the device.getServiceObject("Service.Calendar", "IDataSource") method is used.
