Event Conflicts
With the ability to define specific start and end times for any
event, it is possible to schedule events that overlap (an event
that starts before a previous event finishes).
An event conflict (time overlap) displays in the Week view as
overlapping time bars and in the Day view as overlapping
brackets to the left of the conflicting times.
Month View
The Month View displays days that events are scheduled with
dots and lines throughout the Month. The dots and lines
indicate events, repeating events, and untimed events.
ᮣ Dashed Line - Indicates a repeating event.
ᮣ Dots on right side - Indicates a single event.
ᮣ Dots below - Indicate untimed events.
