Calendar notes: what to plan around

Long weekends and breaks

Every stretch of three or more days with no school, counting weekends. A half day next to a weekend adds half a day.

• 3-day weekend: Saturday, Sept. 5 to Monday, Sept. 7. Labor Day. Back Tuesday, Sept. 8.
• 9 days off in a row: Saturday, Sept. 19 to Sunday, Sept. 27. Fall break. Back Monday, Sept. 28.
• 9 days off in a row: Saturday, Nov. 21 to Sunday, Nov. 29. Thanksgiving break. Back Monday, Nov. 30.
• 17.5 days off in a row: Friday, Dec. 18 at early dismissal to Monday, Jan. 4. Last day before winter holidays early release, winter holidays and teacher workday (no school for students). Back Tuesday, Jan. 5.
• 3-day weekend: Saturday, Jan. 16 to Monday, Jan. 18. Martin Luther King Jr. Day. Back Tuesday, Jan. 19.
• 9 days off in a row: Saturday, Feb. 13 to Sunday, Feb. 21. Winter break (February). Back Monday, Feb. 22.
• 9 days off in a row: Saturday, April 3 to Sunday, April 11. Spring break. Back Monday, April 12.
• 2.5-day weekend: Saturday, May 15 to Sunday, May 16. A regular weekend. Monday, May 17, an early release day.

One early release on a Friday or Monday makes a 2.5-day weekend.

Weeks with fewer than five school days

Five weeks have fewer than five school days, and six weeks have none at all.

Teacher workdays: no school for students

Two of the days off are staff days. Teachers work; students stay home. Plan child care as you would for a holiday.

• Tuesday, Nov. 3: Election Day (no school for students)
• Monday, Jan. 4: teacher workday (no school for students)

Makeup days

The calendar names no makeup days. If school closes for weather, the district announces how the day is made up.

Also worth knowing

• School is open on some federal holidays: Columbus Day (Monday, Oct. 12) and Veterans Day (Wednesday, Nov. 11). Banks, post offices and many offices close; school does not.
• The calendar prints no testing dates. Cobb posts separate elementary, middle and high school testing calendars on its calendar page.
• Remote school days: Monday, Aug. 17, Monday, Oct. 12, Tuesday, Dec. 1 and Monday, March 1. It counts as a school day, but students learn at home. Plan for a child at home.
• After the last day, the calendar still shows Post-planning (teachers only) (May 20) and Memorial Day (May 31). Students are already out.

First and last day of school

The first day of school is Monday, Aug. 3, 2026. The last day is Wednesday, May 19, 2027, with early dismissal.

Teachers start sooner. Staff days before school run July 27 to 31.

Grading periods

Cobb grades in nine-week quarters, two to a semester. The quarter dates come from the district's 2026-27 Staff Use Calendar, which also marks the end of each 4½-week and six-week stretch.

What the district notes

• Digital Learning Days (Aug. 17, Oct. 12, Dec. 1 and March 1) are school days at home while teachers attend professional development. Students work on teacher-made assignments posted in CTLS, with no live instruction. Elementary assignments are not graded.
• Early release times are not printed on the calendar. Schools share the dismissal time.
• High school commencements run May 16 to 23, 2027. The ceremony schedule was still to be announced when the staff calendar was printed.
• Cobb school start and end times differ by level: most elementary schools 7:45 or 7:50 a.m. to 2:15 or 2:20 p.m., middle schools 9:15 a.m. to 4:15 p.m., high schools 8:20 a.m. to 3:30 p.m.

How we checked these dates

We read every date off the district's own calendar twice: once from the PDF's text and once from the image, cell by cell against its legend. Then we checked each one against the Cobb Calendar page, the Cobb 2026-2027 Staff Use Calendar and the Digital Learning Days page on the district's site.

Every weekday on this page matches its date. If the district changes its calendar, its page is the final word.
