Connect your Canvas account to sync assignments automatically.
Calendar feed
Subscribe in Google Calendar (Other calendars → From URL) to see due dates as
all-day events, one per assignment. Assignments are kept fresh automatically —
Canvas is re-synced in the background every 30 minutes, and this feed always reflects
the latest data. Google itself only re-checks subscribed URLs every so often (usually
within a day), which is on Google's schedule, not this app's.
