Terms will not show on your calendar page. Your cancellation policy, which is selected in Terms, will show on your actual Listing Description. If you specify terms such as minimum stay, that minimum will simply be implemented in the calendar. For example, with a 2 night minimum, a checkin date of x will only allow a checkout date longer x+2 and will have a note on the calendar bottom that states 'the minimum stay for this period is 2 nights'.
Also, please be aware that changes in your cancellation policy only affect future reservations. Anyone who booked under the old policy gets to keep it regardless of when their actual checkin date is.
