We are in the process of moving to MySOSM (Blackbaud School Management System). You received an email in May about this upgrade (read it here). While we transition, some events or event details may not be displayed on this calendar.
Please see the link below for the 2025-2026 Calendar Highlights, which was sent to all school families in April. This includes all the days off, breaks, early dismissals, etc. The second page of the PDF contains all the special days (e.g., Special Person Day, Catholic Schools Week) that were available at the time of publishing. We are working diligently and will email all families when MySOSM is available.
Thank you for your patience.
