To add an event to an external calendar, such as MS Outlook, Apple iCal, or Google Calendar, go to the event page in public view and open the event details. In the top-right corner of the event details, click Add to my calendar.
An .ICS (iCalendar) file will be generated containing the event details and a link to the event page. The file will be downloaded via your browser.
You can now import the downloaded .ICS file into most calendar programs, including MS Outlook, Apple iCal, and Google Calendar. Your calendar program will automatically use the timezone of the event to set the equivalent event time in your calendar.
For instructions on importing the .ICS file into different calendar programs, see Adding an event to your calendar program.
