The CascadeOC calendar can be added to your calendar by either subscribing or downloading.
To subscribe to the calendar, copy and paste the URL below into your calendar settings. By subscribing to the calendar, any changes or additions to the calendar that the calendar owner (CascadeOC) makes will appear on your calendar. You will not be able to edit these events on your calendar.
Alternatively, you may download the calendar file and import it into your calendar. By downloading a file, you will get a snapshot of the calendar as it exists currently, and you will not get any changes or additions to the calendar unless you download and import the file again. You are able to edit (and delete) individual events from a downloaded calendar.
