Planning Notes
Cook County Schools' 2026-2027 page centers on Spring Break and the other dated breaks families compare across Georgia districts.
Cook County Schools' 2026-2027 source gives August 5, 2026 as the first student date and May 20, 2027 as the final student date.
Cook County Schools separates 4 multi-day break blocks and 2 one-day break labels: Fall Break on October 9-12, 2026; Thanksgiving Break on November 23-27, 2026; Christmas Break on December 21, 2026 through January 1, 2027; Winter Break on February 15, 2027; March Holiday on March 15, 2027; Spring Break on March 29-April 2, 2027.
Early-release or half-day entries are separate from full breaks: Last Day - Half Day on May 20, 2027. Staff workday, conference, or student-holiday labels include Teacher InService on September 8, 2026; Teacher InService on October 13, 2026; Teacher InService on December 18, 2026; Teacher InService on January 4, 2027; Teacher InService on January 5, 2027; plus 2 more entries in the date table.

One source detail worth preserving: Christmas Break crosses the calendar year from December 21, 2026 through January 1, 2027, which is the date range to check when planning the January return. The final student date, May 20, 2027, is also labeled Last Day - Half Day.
