BCPS Calendar 2026-2027: Baltimore County Public Schools Dates, Holidays, and A/B Day Schedule

The BCPS Calendar 2026-2027 is the official, Board of Education–adopted instructional schedule for Baltimore County Public Schools (BCPS), the Maryland school system headquartered in Towson, Maryland 21204.

Baltimore County Public Schools enrolls more than 111,000 students across 176 schools and operates a bus system that transports over 77,000 students twice daily, hiring teachers, administrators, and support staff to serve that population and running school buses across the county each day.

This calendar governs when those students attend class, when staff reports for duty, and when the district’s four marking periods begin and end.

BCPS adopted the 2026-2027 calendar on November 4, 2025, under a Pre-Labor Day Start format: classes open on Monday, August 31, 2026, and close no later than Thursday, June 17, 2027.

This guide breaks down every published date on the calendar — holidays, marking-period endpoints, the A/B day rotation for secondary schools, report-card distribution, and commencement — using the terminology and structure BCPS itself uses in the official PDF calendar.

BCPS Calendar 2026-2027 at a Glance

The BCPS Calendar 2026-2027 begins Monday, August 31, 2026, and ends Thursday, June 17, 2027, or Monday, June 14, 2027, if Baltimore County Public Schools uses none of its three built-in inclement-weather make-up days.

The calendar allots 183 to 184 total student days and up to 194 staff duty days, organized into four marking periods.

When Does the BCPS 2026-2027 School Year Start and End?

First Day of School: Monday, August 31, 2026

BCPS students begin full attendance on Monday, August 31, 2026, the calendar’s designated Opening Day for Students.

Staff reports earlier than students: administrative and supervisory personnel meet Friday, August 21, 2026; teachers and school-based staff report for duty Monday, August 24, 2026; systemwide professional development runs Tuesday, August 25, 2026; and teacher classroom preparation days fall on Wednesday, August 26, 2026, and Friday, August 28, 2026.

Students entering grades 6 and 9 attend a separate orientation on Thursday, August 27, 2026.

Kindergarten follows a distinct start: the first full day of kindergarten, when transportation begins, is Wednesday, September 2, 2026 — three school days after the general Opening Day.

Last Day of School and How Inclement Weather Changes It

The last day of school depends on how many emergency closures BCPS uses during the year. If the district uses all three built-in inclement-weather make-up days, classes run through Thursday, June 17, 2027, which also serves as the last day for teachers.

If no emergency closures occur, instruction ends earlier, on Monday, June 14, 2027, and the assessment days, along with the last day for prekindergarten and teachers, shift accordingly.

This dual-date structure differs from a fixed single end date and directly affects how families should plan summer travel around the calendar.

BCPS Calendar 2026-2027 Inclement Weather Make-Up Days

Three make-up days are pre-built into the calendar in case of snow days, delayed openings, or other emergency closures:

• Emergency Closure #1 Make-Up Day: Tuesday, June 15, 2027
• Emergency Closure #2 Make-Up Day: Wednesday, June 16, 2027
• Emergency Closure #3 Make-Up Day: Thursday, June 17, 2027

If BCPS records more than three emergency closures in a school year, the district implements virtual learning instead of adding more in-person make-up days, capped at a total of eight virtual days.

Beyond that threshold, the calendar itself may be adjusted — through re-designating holidays as student days, shortening spring break, converting professional development days into student days, or canceling planned early releases.

Why the BCPS Calendar Starts Before Labor Day

BCPS uses a Pre-Labor Day Start because Maryland law currently leaves school-year start dates to local boards of education rather than the state.

That local authority is relatively recent: the Maryland General Assembly voted in 2019 to override a gubernatorial veto and return school-calendar authority to local school boards, undoing a 2016 executive order that had required a post-Labor Day start statewide.

Since then, individual Maryland school systems have set their own opening dates, and BCPS has opted for a pre-Labor Day calendar for 2026-2027, opening Monday, August 31, 2026 — one week before Labor Day, Monday, September 7, 2026.

Maryland’s Instructional-Day and Seat-Hour Requirements

Maryland law does not regulate the exact start date, but it does set floors on instructional time. State law requires public schools to be in session for 180 days and to meet minimum seat-hour totals of 1,080 hours at the elementary and middle school levels and 1,170 hours at the high school level.

The BCPS 2026-2027 calendar is built around these same thresholds; the district’s own hour calculations (detailed later in this guide) reference these exact figures.

BCPS Calendar 2026-2027 Holidays and School Closures

BCPS closes schools and offices for some holidays but keeps schools open, with modified programming, on others. Distinguishing between the two matters for anyone planning travel or childcare around the calendar.

Full-Closure Holidays: Schools and Offices Closed

These dates close both schools and district offices for staff and students alike:

Holidays When BCPS Schools Remain Open

Not every nationally recognized holiday closes BCPS schools. Three dates on the 2026-2027 calendar carry an asterisk marking them as days when “schools open with appropriate exercises,” meaning classes are in session but include holiday-related programming:

• Columbus Day / Indigenous Peoples’ Day: Monday, October 12, 2026 — schools open, in session
• Veterans Day: Wednesday, November 11, 2026 — schools open, in session
• Maryland Day: Thursday, March 25, 2027 — schools open, in session

This is a distinction generic calendar listings frequently miss: Veterans Day, in particular, is a federal holiday that does not translate into a BCPS school closure.

Religious Observance Closures on the 2026-2027 Calendar

BCPS schedules three systemwide professional development days around major religious observances, closing schools for students while keeping teachers on duty:

• Yom Kippur: Monday, September 21, 2026
• Eid al-Fitr: Wednesday, March 10, 2027
• Eid al-Adha: Monday, May 17, 2027

On these dates, students do not attend class, but staff report for professional development activities rather than taking the day off.

The table below lists every dated event on the official BCPS 2026-2027 calendar, from Opening Day through the end of summer school.

Marking Periods, Report Cards, and Grading Windows

BCPS 2026-2027 Marking Period End Dates

BCPS divides the 2026-2027 school year into four marking periods, three of which have confirmed end dates published directly on the calendar.

Marking Period 1 ends Friday, October 30, 2026; Marking Period 2 ends Friday, January 15, 2027; and Marking Period 3 ends Friday, April 2, 2027. Each of these end dates triggers a 3-hour early dismissal for grade reporting and data analysis.

The fourth marking period concludes with the last day of classes — Thursday, June 17, 2027, under the worst-case snow-day scenario, or Monday, June 14, 2027, if no make-up days are needed; the calendar does not separately publish a distinct Marking Period 4 end date beyond this.

Report Card Distribution Dates

BCPS publishes three report card distribution dates on the 2026-2027 calendar: Thursday, November 12, 2026 (Marking Period 1); Thursday, January 28, 2027 (Marking Period 2); and Thursday, April 15, 2027 (Marking Period 3).

The calendar does not list a separate distribution date for Marking Period 4 report cards, since the marking period ends at or near the close of the school year.

BCPS Winter Break and Spring Break 2026-2027

Winter Break: December 24, 2026 – January 3, 2027

Winter break begins at the end of the school day on Wednesday, December 23, 2026, and runs through Sunday, January 3, 2027 — an 11-calendar-day closure. Students and staff return Monday, January 4, 2027.

Spring Break: March 20–29, 2027

Spring break begins at the end of the school day on Friday, March 19, 2027, and runs through Monday, March 29, 2027 — a 10-calendar-day closure. Schools reopen Tuesday, March 30, 2027.

BCPS A/B Day Schedule Explained

How the BCPS Calendar 2026-2027 A/B Rotation Works

BCPS secondary schools follow a continuous A/B day rotation rather than a fixed Monday-through-Friday subject schedule, meaning each in-session school day is designated either “A” or “B” regardless of the day of the week.

Opening Day, Monday, August 31, 2026, is designated an A day, and the rotation then advances one letter per school day held.

Because the sequence only advances on days students actually attend, holidays, closures, and non-attendance days do not break the count — the rotation simply resumes on the letter it left off on when school reconvenes.

Professional Development Days That Interrupt the Rotation

Systemwide professional development days are marked separately as “PD” days rather than being assigned an A or B designation, since no students attend.

These interruption points fall on Monday, September 21, 2026; Friday, October 16, 2026; Tuesday, January 19, 2027; Wednesday, March 10, 2027; and Monday, May 17, 2027.

On the final three assessment days of the school year, BCPS allows the rotation to be adjusted at the principal’s discretion, provided staff, students, and parents are notified in advance.

Instructional Hours and Minimum Day Requirements by School Level

BCPS calculates instructional-hour compliance separately for elementary schools versus middle and high schools, because Maryland’s required minimums differ by level.

The table below reproduces the district’s own hour math from the adopted calendar, based on a 6.75-hour student day and three emergency closure days deducted from the printed total.

High schools carry the smallest hour cushion of the three levels — 30.75 hours above the state minimum — because Maryland requires 90 more seat-hours at the high school level than at elementary or middle school.

Teacher duty days across the system will not exceed 191, even though total staff-day entries on the calendar sum to 194 when non-teaching staff duty days are included.

BCPS Graduation and Commencement Schedule 2027

Last Day for Seniors and Commencement Exercise Dates

The last day of school for BCPS seniors is Friday, May 21, 2027, roughly four weeks before the general student calendar closes.

Commencement exercises for the graduating class span two separate windows: Monday, May 24, 2027, through Saturday, May 29, 2027, and Tuesday, June 1, 2027, through Saturday, June 5, 2027.

BCPS spreads commencement across these two multi-day blocks to accommodate ceremonies for its 176 schools rather than holding a single systemwide date.

Does the BCPS Calendar Sync with Schoology?

Schoology functions as Baltimore County Public Schools’ official learning management system, and families access it through the BCPS One portal at bcpsone.bcps.org. Parents and guardians with a myBCPS account receive access to Schoology through BCPS One, where they can view student courses, grades, and assignments.

This guide compiles the same holiday, marking-period, and closure dates published in the district’s official adopted PDF calendar; individual schools may additionally post select events to their Schoology course calendars, but the Board-adopted PDF calendar remains the source of record for districtwide dates such as holidays and marking-period endpoints.

What This BCPS Calendar 2026-2027 Guide Does Not Cover

This guide addresses the systemwide student and staff instructional calendar only.

It does not cover: BCPS employee pay-date or payroll calendars, which are published separately from the instructional calendar; individual school event calendars, such as back-to-school nights or athletic schedules; standardized testing windows set by the Maryland State Department of Education; or after-school and extracurricular program calendars, which vary by school.

Families and staff needing those specific schedules should consult bcps.org directly, since they are not part of the Board-adopted instructional calendar analyzed here.
