website/components/academic-calendar/calendar-content.tsx uses useAcademicYears, useAcademicCalendar, useDefaultAcademicYear. Default year is 2627 when that file exists.

Files: website/data/calender/2425.json, 2526.json, 2627.json (note the directory spelling calender).

{ summary: string; start: { date: string }; end: { date: string } }

API year list maps 2627 → label 2026-27. Event route reads {year}.json from DATA_DIR/calender.

Holidays: summary.startsWith("Holiday -").

Upcoming vs past split on start.date vs today. A divider scrolls into view.

website/utils/calendar-AC.ts builds all-day VEVENTs (VALUE=DATE, end = next day). Google path uses GSI + Calendar API, same client ID as the timetable button. iCal download is local.
