Arapahoe County Colorado Schools Calendar

Five districts hold most of the students in this metro county south and east of Denver, and Cherry Creek School District 5 alone enrolls more than 50,000 of them. Add Littleton Public Schools, Englewood Schools, Sheridan School District 2, and the Arapahoe County portion of Aurora Public Schools, and the county’s public school population is well over 100,000. Each district’s elected board adopts its own calendar, so a family in Greenwood Village and a family in Deer Trail can face very different schedules.

School District Structure in Arapahoe County

Colorado has no countywide school system, and Arapahoe County government has no say in school calendars. The county seat is Littleton, but education is run entirely by local school districts, each with an elected Board of Education that hires a superintendent. Districts serving Arapahoe County include:

• Cherry Creek School District 5: the largest district based in the county, serving Greenwood Village, Cherry Hills Village, Centennial, Foxfield, Glendale, and parts of Aurora. Its administration is in Greenwood Village.
• Aurora Public Schools (Adams-Arapahoe 28J): serves much of Aurora and spans two counties, so its calendar affects families on both sides of the Adams-Arapahoe line.
• Littleton Public Schools (District 6): serves Littleton and neighboring areas, and its boundaries extend into Jefferson and Douglas counties.
• Englewood Schools (District 1): a compact urban district serving the city of Englewood.
• Sheridan School District 2: a small district serving Sheridan and adjacent neighborhoods.
• Deer Trail School District 26J: a small rural district on the Eastern Plains.
• Byers School District 32J, Strasburg School District 31J, and Bennett School District 29J: rural Eastern Plains districts that each reach into the county’s eastern reaches.

Each board generally meets on a regular schedule, often monthly, with agendas and minutes posted online. If you are unsure which district serves your address, the county assessor’s office or a district enrollment office can confirm it.

Academic Calendar Structure

Most suburban districts in the county, including Cherry Creek, Littleton, Englewood, Sheridan, and Aurora, begin classes in mid-August and finish in late May or the first days of June. Boards typically approve the next year’s calendar in the spring, and some adopt calendars a year or more ahead. Exact first and last days change annually, so use the current board-approved version rather than a past year’s dates.

Most districts divide the year into two semesters, with the fall semester ending near winter break and the spring semester starting in early January. Secondary schools usually report by quarter or semester, while elementary schools may use trimesters or quarters. Your school’s handbook shows which applies.

Colorado sets minimum instructional time mostly in hours: 1,080 for secondary students, 990 for elementary students, and 450 for half-day kindergarten, with a 160-day standard that hour-based calendars can satisfy. Larger suburban districts such as Cherry Creek generally meet this with a conventional five-day week. Smaller rural districts on the Eastern Plains, where bus rides are long, may use longer days across a four-day week. If you live in the Deer Trail or Byers area, confirm the weekly schedule.

Bell times vary. Elementary, middle, and high schools in a district commonly start at staggered times to coordinate bus runs, and the arrangement differs between Cherry Creek, Littleton, and Aurora. Check your school’s page or enrollment packet for exact times.

School Holidays and Breaks

The districts here follow a broadly similar set of breaks, but details differ by board:

• Labor Day: first Monday of September, schools closed.
• Fall break: some districts schedule a few days off in October, often combined with conferences. Others do not.
• Thanksgiving break: usually Wednesday through Friday or the full week.
• Winter break: typically about two weeks around Christmas and New Year’s Day.
• Martin Luther King Jr. Day: third Monday of January.
• Presidents’ Day: usually a day off in February.
• Spring break: generally one week in March, often similar across Front Range districts, though not always the same week.
• Memorial Day: last Monday of May.

Colorado does not mandate a list of school holidays beyond the instructional-time minimums, so each board decides.

Comparing Calendars Across Colorado Counties

Because this part of the metro area includes districts that cross county lines, many families end up comparing calendars. The Arapahoe County schools calendar reflects a dense suburban and urban setup with several districts and a mid-August start. By contrast, the Alamosa County schools calendar reflects a rural, high-altitude setting in the San Luis Valley with just two districts. Looking at them side by side shows how Colorado’s local control produces different start dates, break lengths, and weather policies within the same state, which matters for families who relocate, share custody, or coordinate travel.

How to Find the Official Arapahoe County School Calendar

No single office publishes a countywide calendar. Go to the website of the district that serves your address, such as Cherry Creek School District 5, Littleton Public Schools, Englewood Schools, Sheridan School District 2, or Aurora Public Schools. Calendars are normally approved at a regular Board of Education meeting in the spring, then posted as a PDF or interactive calendar under tabs such as “Calendar,” “Families,” “Parents,” or “Community.” Many districts also provide a feed you can add to your phone.

Individual schools often keep supplemental calendars for concerts, conferences, assemblies, and athletics, so check your child’s school page as well as the district’s.

Early Release Days, Teacher Workdays, and Professional Development

Teachers generally report several days before students for planning and training. During the year, districts schedule professional development days when students stay home. Some also use early release or late start days so staff can collaborate, and the frequency varies widely between districts. Families usually hear about these through the school calendar, newsletters, automated calls and texts, and the student information portal.

Colorado requires some staff training, including child abuse recognition and mandatory reporting, but each district decides when to hold it.

Emergency Closures and Weather Days

Arapahoe County sits on the Front Range and the Eastern Plains, where weather swings quickly. Spring snowstorms, hard cold snaps, and high winds can all disrupt school. Conditions can differ across the county: a storm may be manageable in Englewood or Littleton and far worse on the open plains near Deer Trail and Byers, where unplowed rural roads weigh heavily in transportation decisions.

The superintendent or a designee usually decides early in the morning after consulting transportation staff and weather forecasts. Options include a full closure, a delayed start, or an early release. Notices usually go out through:

• Automated calls, texts, and emails from the district
• The district website, mobile app, and social media
• Denver-area television stations such as 9NEWS, Denver7, FOX31, and CBS Colorado
• Local radio

Because the larger districts share a metro media market, closure announcements for several districts appear together. Make sure you check your own district’s name. Makeup policies vary. Some districts build extra time into the calendar, and some use remote learning days instead of canceling instruction, so read your district’s weather policy.

Graduation and End-of-Year Schedule

High school final exams generally fall in the last week or so of the school year, followed by graduation ceremonies in mid to late May. Larger districts commonly hold ceremonies at stadiums, event centers, or other large venues in the metro area, while small rural districts may hold them on campus. Elementary and middle schools often hold promotion or recognition events in the final week. Final report cards and transcripts are generally available through the district portal after the term ends, though access during summer varies.

Back-to-School and Registration Information

New families should first confirm which district serves their address. Colorado has school choice enrollment, and Cherry Creek, Aurora, and Littleton each run their own processes, so families can apply to schools outside their attendance zone within district-set windows. Contact your district for dates.

Commonly requested documents include:

• Proof of residency, such as a lease, utility bill, or mortgage statement
• Proof of the child’s age, such as a birth certificate
• Immunization records or an approved exemption
• Records from the previous school, if transferring

Most districts offer online registration along with help from a central office or the school. Supply lists are usually posted in July or early August, and many schools host open houses or meet-the-teacher events shortly before classes begin.

Special Programs and Their Calendar Implications

Several programs may follow different schedules. Magnet, charter, and specialty programs can set calendars that start earlier or end later than neighborhood schools. Cherry Creek’s Innovation Campus offers career and technical programs that combine school and workplace learning, so check its schedule separately. Students in dual enrollment courses, such as those through Arapahoe Community College in Littleton or the Community College of Aurora, follow the college calendar for those classes. Alternative schools may run flexible hours, and Colorado’s Universal Preschool program serves four-year-olds with providers whose calendars may differ from the K-12 year. Online options, whether district-run or statewide, may also follow different calendars.

Athletics and Extracurricular Calendar Context

High school athletics are governed by the Colorado High School Activities Association (CHSAA), which sets season dates, eligibility rules, and postseason schedules. These are separate from the academic calendar but intersect with it. Fall sports begin in August around the first days of school, and winter and spring seasons collide with exam periods and spring break. Large districts such as Cherry Creek have extensive athletic programs, so weekend and evening events can be numerous. Check athletic schedules separately from the academic calendar.

State-Level Calendar Requirements and How Colorado Law Governs Arapahoe County

The Colorado Department of Education (CDE) administers state education law, and the State Board of Education adopts regulations. The state sets minimum instructional hours but leaves start dates, holidays, and weekly structure to local boards. That is why Cherry Creek, Littleton, Aurora, and the rural plains districts can have different calendars. Districts that adopt nontraditional schedules, such as four-day weeks, must still meet the hour requirements. Questions about state rules can go to CDE.
