How we counted, and where this comes from
We read the official Baltimore County 2026-27 calendar on October 4, 2026: https://cdnsm5-ss3.sharpschool.com/UserFiles/Servers/Server_2744/File/Calendars/2026-2027/26-27%20BCPS%20Pre-Labor%20Day%20Calendar.pdf. A day counts when school is closed for all students on a weekday, or the whole district lets students out early. Holidays that almost every employer observes (Labor Day, Thanksgiving, Christmas Day, New Year’s Day, Martin Luther King Jr. Day and Memorial Day) are never counted. Indigenous Peoples’ Day, Veterans Day and Presidents’ Day count as holidays only when the district closes school for that holiday by name, because many employers stay open. That left 7 holidays out of the count here. School ends Monday June 14 unless snow or emergency closures use the make-up days June 15-17; elementary students are also off Monday Nov 16 (middle and high attend) and kindergarten is off Friday Apr 16. Calendars change and some days vary by school, so check with your school before you book childcare.
