PSO Calendar

Events for the entire 2026-2027 school year have been published to the public PSO Google Calendar! Separate from the official GHNO calendar, this calendar will have PSO specific events (i.e. events that will need volunteers, PSO meetings, community building and social events, and anything related to PSO).  

To sync the GHNO Family Calendar to an iPhone: 

Click your Calendar app, click calendars at the bottom, click, add calendar, then click add subscription calendar and paste the following into the box:

On the left side of the screen, find the Other calendars section.
