The system by default displays two appointments before it begins to stack the appointments and summarize important details. Clicking on a stacked date will take you to the day view for that date. Clicking an appointment on an unstacked date will open the appointment pop-up. A yellow line to the left of an unstacked appointment indicates a time before noon, gray indicates afternoon. You can also click the small plus on any current or future date to start creating an appointment for that particular date.
