Issue:

Is there a shared Google calendar that students and parents can download for WSU holidays and major school events?

Solution:

Currently the only calendars WSU provides are displayed below:
Academic Calendar: https://registrar.wsu.edu/academic-calendar 
Scheduling Office Campus Calendars: https://scheduling.wsu.edu/Content/campuscalendar.aspx
Listing of Events Calendars: https://wsu.edu/life/events/
Final Exam Schedules: https://registrar.wsu.edu/final-exam-schedules/
 
WSU displays all events and calendars within a web page for communication to the public, which allows for the greatest distribution of information via this web page. 
This provide details about these events and also allows anyone to add the events to their personal Google or Outlook calendars.
