I'm using FullCalendar on a project where users primarily have a single event that lasts multiple days or weeks, with multiple other events scattered throughout. I've had a handfull of users say that they're confused by which day the events are being shown in, quote:
the [event] line being dark across the board causes your eyes to associate the date number with the wrong date box
They are associating the space above the line as the day. So for example they want to set something for the 16th so they click on the space above the 16th which in this example selects the 9th.
I can't "make myself see it" - the dates are in boxes with events that span date boxes. Also, how we have it lain out seems like a pretty standard user interface. Here's a screenshot, explaining, with other interfaces linked below for comparison:
Does anyone have any recommendation on how I can reduce the confusion for my users? Some of them suggest moving the event above the date number, which seems very wrong and much more confusing.
