GCSD is a suburban school district with 7 schools. For the 2026-2027 school year, classes begin September 8 and end June 25. Guilderland High School's teams are known as the Flying Dutchmen, a nod to the area's Dutch colonial heritage in the Capital Region of New York. The calendar also notes several religious observances (Rosh Hashanah (Saturday), Yom Kippur / School Recess Day, Diwali (Sunday), Lunar New Year (Saturday), Eid Al-Fitr / Supt. Conference Day) for awareness — school stays in session on these days. This calendar includes 1 early-release or half day — useful to know when planning childcare.
