Adding to your calendar
You can choose to add an event or calendar to any calendaring application that supports the standard interchange format for calendars and events. Examples include Google Calendar, Microsoft Outlook, Apple iCal, Mozilla Sunbird, etc. An add to Google calendar button for individual events is provided for your convenience.
You may also get the .ics file for an individual event or calendar. This file should be recognized by most calendaring applications and be imported into your calendar.
