The calendar window controls the current date in the system. You select a new date by clicking on the corresponding day on the calendar. This will automatically update schedule and billing windows. To change the month click the arrows on either side of the month name.
The current day is shown at the top of this window and the complete date is shown in the information bar at the top of the page.
When you resize the calendar window, the calendar grows to fill the window.
There’s only one setting for the calendar window. It’s called size. This setting refers to the size of the text. The larger the number, the bigger the text on the calendar.
