​
How It Works

EmptyClassroom fetches data from Boston University’s room reservation system and intelligently calculates available time slots based on:
  • Official class schedules
  • Room reservations and bookings
  • Building operating hours (CAS: 7am-11pm, CGS: 7am-9:30pm)
  • Minimum viable study time (30+ minute gaps)
Important: Displayed availability reflects official schedules only. Rooms may occasionally be occupied by unofficial meetings or study groups.
