This is the calendar for the entire district. If you would like to see fewer sections, click on the down-arrow button in the upper-right corner of the calendar. From there, you can turn on or off different categories of events. (For example, if you only want to see events relating to Cairo-Durham High School, you can check "School Closings," "High School Events," and "Athletics" and then uncheck all other categories.)
