Cobb starts early and finishes early: the first day of school is Monday, August 3, 2026 and the last day is Wednesday, May 19, 2027, with a full week off for fall break in September and a second week-long break in February on top of Thanksgiving, winter and spring holidays.
Here is the whole year as the district published it, in one table you can actually scroll on a phone, and then the five-minute way to get it onto your own calendar beside the practices and games.
Source: Cobb County 2026-27 Year at a Glance (PDF) and the district's 2026-27 staff-use calendar (PDF). Last checked October 28, 2026. The one-page calendar is marked "Revised: 3/11/26"; the staff-use calendar is dated 4/23/26, and the two agree on every date listed here.
Every date below is copied from the district's own published calendar, not estimated. Districts do revise mid-year, so confirm against the source before you book anything around a date.
24 published entries, 10 of them closures or breaks and 4 flagged early release. A single entry can cover a span of days. Labels are the district's wording.

The district marks August 17, October 12, December 1 and March 1 as Digital Learning Days, with a legend entry separate from both "Holiday – School Closed" and "Student Holiday/Staff Day". The published calendar does not describe what a Digital Learning Day looks like at your school, so treat the date as a flag and ask the school what it means for your child.
October 13–16 is Elementary & Middle School Conference Days. The calendar's own wording is "early release for elementary and middle schools only" — a high-schooler on the same calendar keeps a normal dismissal that week.
All levels release early on December 17 and 18 (the last two days of first semester) and on May 17, 18 and 19 (the last three days of the year). The district does not print dismissal times on the year-at-a-glance; those come from your school.
Tuesday, November 3, 2026 is listed as a Student Holiday with a Local School Professional Learning Day for staff, so there is no school that day even though it is not a federal holiday on the calendar.
Fall break September 21–25, winter break February 15–19 and spring break April 5–9 are each a full Monday-to-Friday week, and Thanksgiving (November 23–27) is a full week as well. Winter holidays run December 21 through January 1, with January 4 a student holiday and the second semester starting Tuesday, January 5.
The quick way: create a free Schedule Caddie account from this page and the 2026-27 calendar above is already on it as your own schedule — the version we verified on October 28, 2026, yours to edit. If Cobb County revises the calendar later, upload the new version and you see exactly which days changed before approving them.
Doing it yourself, or a different district:
The district publishes this calendar as a document, not a feed you can subscribe to. Schedule Caddie reads that document for you: download the 2026-27 calendar from the district (the source link above), upload it as a PDF, PNG, or JPG up to 10MB, and it pulls out the no-school days, breaks, early releases with their dismissal times, teacher days, and the first and last day of school.
Nothing is saved until you have looked at it. Every day it found shows up as its own row with the date and label, you uncheck what you don't want and fix anything it misread, and only then does it land on your family calendar, color-coded as School so a holiday Monday reads differently from a 4pm practice. Team schedules you have added as calendar links keep refreshing on their own; the school year sits beside them.
Either way it travels like anything else on your Schedule Caddie calendar: subscribe to your Schedule Caddie link in Google Calendar, Apple Calendar, or Outlook and the school days come along.

The first day of school is Monday, August 3, 2026. The first semester ends Friday, December 18 (an early release day), the second semester begins Tuesday, January 5, 2027, and the last day of school is Wednesday, May 19, 2027, also an early release day.
Monday, September 21 through Friday, September 25, 2026, listed as Fall Break – Student/Teacher Holidays. The next week-long breaks are Thanksgiving (November 23–27), winter break (February 15–19, 2027) and spring break (April 5–9, 2027).
Not according to the calendar. The district gives Digital Learning Days their own legend entry, distinct from "Holiday – School Closed" and "Student Holiday/Staff Day", and lists four of them: August 17, October 12, December 1 and March 1. What your child is expected to do on those days is set by the school, so check there rather than assuming a free day.
December 17 and 18, 2026 and May 17, 18 and 19, 2027 for all levels, plus October 13–16, 2026 for elementary and middle schools only (conference week). Dismissal times are not on the district calendar; your school publishes them.
Every kid, every schedule, every app — merged, color-coded, and watched for changes.
