Note: Linked on the district calendar page as the 2027-28 district calendar (grid dated June 22, 2026). The version posted for the spring 2026 calendar survey was marked DRAFT; this one is not, but neither the document nor the page states an approval. Break names come from the listed 'District Calendar 2027-28' on the same page, which agrees with this grid. Oct. 18 and March 6 are staff development days with no school for students. Grades 9-12 also have no school on Friday, Jan. 14, 2028 (Teacher Work Day/Student Holiday, traditional schools only); PK-8 students attend that day. PK-8 schools instead have one floating teacher work day in October whose date is not on the district calendar (check with your school); both groups have 180 instructional days (the grid's monthly counts: October 20 for high school and 19 for PK-8, January 19 for high school and 20 for PK-8). Lincoln's Day is observed on Nov. 24, inside Thanksgiving week. Juneteenth (June 19) falls after the last day of school.
