The Upper Darby School District calendar includes events, activities and important deadlines for the school year. Updates may be made to this calendar as the year progresses, so please visit this page often to stay up-to-date.  School buildings keep their own calendars of events on their webpages that include dates for school-related events. Please visit your school building website for more information. You can also access the district and school-level calendars on the Upper Darby School District mobile app. Visit your App Store to download it today! For general calendar questions, please contact Aaronda Q. Beauford, Director of Communications, at abeauford@upperdarbysd.org.
