This Export button will export all of the events you have chosen to view into a file that you can then import into your own personal calendar.
Please note that if you choose this option, if any events change in date or time, you will not get that automatically updated and you would need to do another export and import.
iCal feed button will pull all of the events into your personal
calendar using an RSS feed. This allows your calendar to continue to
keep the most current changes to any event in your calendar as well.
This is a great way to stay updated.
