I often have events that are 2, 3, or 4 hours. It would help me manage the calendar if the duration or end time were shown on the main calendar display, or at minimum an alternative display mode that would show start and end times. I would like to share one of my calendars with someone who will be modifying it. In order to see when I am busy, they need to know the duration of each event as well. I know that you can click into an event to see this but that is very labor intensive over a month with many events.
