Cedar Ridge High School Calendar, 2026-2027
This calendar is synthetic : every date, class, and teacher is invented for testing the
Open Study Buddy kit. The same events exist in three forms, all generated from one source list
by scripts/build-school-calendar.py
File
Used for
events.json The hand-edited JSON event file the buddy server reads first
calendar.ics The iCalendar feed the server parses later (time zone America/Chicago)
this page
A readable copy for students and teachers
Titles follow the TEST: and DUE: convention, so the agent can answer "When is my next test?"
and "What is due this week?" by matching the title prefix.
