Abstract: The calendaring techniques and systems described herein enable a user to more easily resolve conflicts for attendees to an event by visually indicating available time slots for all attendees in a calendar window or in a timeline window separate from the calendar window. The first available time slot may be automatically selected or the user may select an available slot to reschedule the event. In another aspect, inspector windows are displayed within a calendar window to show summary or details for an event. An inspector window can also be displayed when a change to an event is detected. In yet another aspect, calendars for multiple accounts accessible by a user are merged into a single calendar view.
