Help with monthly calendar
 

I have created a few appointments on a monthly calendar spreadsheet. When I
view the calendar (in the monthly view) as well as print the calendar, the
end time for the appointment does not show. For example, for an appointment
that lasts from 9AM-4PM, only 9AM shows up. When I view the calendar in a
daily view or weekly view the end time is visible. This is only a problem on
the monthly view. How do i make the end time for an appointment visible on a
monthly calendar?
