Dallas ISD starts on a Tuesday and finishes on a Wednesday: the first day of class is August 11, 2026 and the last is May 26, 2027. In between, the days that catch families out are the two-day fall break in October, the early-release days that apply to secondary schools only before everyone gets one, the parent-conference days split by school level, and the two Mondays the district holds in reserve for bad weather.
Here is the district's traditional calendar, every entry, in the district's own words and in one table you can scroll on a phone — then how to get it onto your own calendar beside the practices and games.
Source: Dallas ISD 2026–2027 Calendar, Traditional (PDF) and Dallas ISD Approved Calendars. Last checked November 6, 2026. This is the district's Traditional calendar (its PDF is titled "2026–2027 Calendar/Calendario"); Dallas ISD also publishes a separate ADSY (Additional Days School Year) calendar for early-start campuses, which begins July 28 and adds instructional days.
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.
33 published entries, 12 of them closures or breaks and 3 flagged early release. A single entry can cover a span of days. Labels are the district's wording.

Dallas ISD publishes two 2026-27 calendars. This page is the Traditional one (first day of class August 11). The ADSY calendar, for Additional Days School Year campuses, starts July 28, 2026 and adds instructional days during the year (July 28–August 10, plus five single added days between September and February), while sharing the same holidays, breaks and May 26 last day. If your campus is ADSY, use the district's ADSY PDF instead.
The calendar lists December 16–17 and May 24–25 as early release for "Secondary only", and December 18 and May 26 as early release for "All schools". An elementary student keeps a normal day on the secondary-only dates. The district does not print dismissal times on the calendar; those come from your campus.
Fall conferences are October 19 (High School), October 20 (Middle School) and October 22 (Elementary School); spring conferences are January 25 (High School), January 26 (Middle School) and January 28 (Elementary School). The calendar lists the dates only — it does not say whether they change the school day, so check with your campus.
March 29 and April 19, 2027 are listed as Inclement Weather Days. The calendar does not spell out the mechanics, but a reserved make-up day is one not to book a trip on until the district confirms it will not be needed.
The printed calendar lists Professional Development for August 3–6, October 12, November 3 and January 5, and Teacher Workdays for August 3, 7 and 10 and May 27, as categories separate from "Staff/Student Holiday" and without saying whether students attend. The district's own events calendar at dallasisd.org settles it: Monday, October 12, Tuesday, November 3 and Tuesday, January 5 are each listed there as "Professional Development/Student Holiday", so students are off on all three; the August and May dates fall outside the student year. The calendar also lists Friday, March 26, 2027 as a Staff/Student Holiday without naming it, and Juneteenth (June 19) and Independence Day (July 4) as holidays that fall on Saturdays outside the student year. Two-day fall break, October 8–9, is "for students and campus team members".
Read off the calendar's bracket markers: August 11–October 9, October 12–December 18, January 6–March 5 and March 8–May 26. The second period begins on a Professional Development day and the third begins the day after one.
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 November 6, 2026, yours to edit. If Dallas ISD 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.

On the traditional calendar, the first day of class is Tuesday, August 11, 2026 and the last day of class is Wednesday, May 26, 2027, which is also an early release day for all schools. ADSY campuses start earlier, on July 28, 2026, and end on the same May 26.
Fall Break is Thursday–Friday, October 8–9, 2026. Thanksgiving Break is Monday–Friday, November 23–27, 2026. Winter Break runs Monday, December 21, 2026 through Monday, January 4, 2027, followed by a Professional Development / Student Holiday on Tuesday, January 5, so students return Wednesday, January 6, when the next nine weeks begins. Spring Break is Monday–Friday, March 15–19, 2027, and Friday, March 26 is an additional Staff/Student Holiday.
December 16–17, 2026 and May 24–25, 2027 for secondary schools only, and December 18, 2026 and May 26, 2027 for all schools. Dismissal times are not on the district calendar; your campus publishes them.
Monday, March 29, 2027 and Monday, April 19, 2027 are listed as Inclement Weather Days on the district calendar. Treat them as dates that could become school days after weather closures and confirm with the district before making plans around them.
Every kid, every schedule, every app — merged, color-coded, and watched for changes.
