The calendars on our site are pulled in from each school's Google Calendar. We have created a page where you can view the all calendars in various configurations.
Following a single calendar
For each of the schools and the district, we have tabs set up for the single calendar. If you want to connect a single calendar to a calendar service you use (Apple Calendar, Google Calendar, Outlook). Even if you are interested in multiple calendars, it might be useful to follow each one individually to keep it organized.
