How to Use the School Year Calendar
The school year calendar reference shows typical dates for traditional calendar schools. Year-round schools, charter schools, private schools, and homeschool programs may follow entirely different schedules. International schools often follow the International Baccalaureate calendar (August–June or local country standards).
Quarter System vs. Semester System
The quarter system divides the year into four 10-week terms. Universities using the quarter system include many UC campuses (Berkeley, Davis, San Diego), Oregon State, Seattle University, and Northwestern. The quarter system offers more scheduling flexibility but means shorter terms with less time to absorb material before finals.
FAQ
Is this school year calendar reference free?
Yes, completely free with no signup. Reference typical academic year dates and schedules for US schools.
When does the school year start?
Most US public schools start between late July and early September. Southern states (Texas, Florida, Georgia) often start in early-to-mid August. Northern and Midwestern states typically start after Labor Day (early September). Year-round schools and charter schools may have different schedules.
How many school days are required per year?
State requirements vary from 170 to 180 instructional days per year. Most states require 180 days. Some states count hours instead (e.g., 1000–1080 instructional hours). This translates to a roughly 9-month academic year with summers off for traditional calendar schools.
What is the difference between semester and quarter systems?
Semester system: two 15-18 week terms (fall and spring) with a winter break between. Most common in US higher education and K-12. Quarter system: four 10-week terms (fall, winter, spring, summer). Less common; used by some universities including many UC campuses, Oregon, and Northwestern.
When are major school breaks?
Fall break: 1 week in October (not universal). Thanksgiving break: 3-5 days in November. Winter/Christmas break: 2 weeks in late December through early January. Spring break: 1 week in March-April. Summer: June through August (traditional calendar schools).
