SysDate shows the day of the month in the system tray (next to the time). This lets you see the current Datum with just a glance, instead of hovering the mouse pointer over the time. Great timesaver for those who are in front of a computer all day! Of course, the display is fully customizable: you can choose to have the Datum shown as a single color, or as an attractive blend of two different colors. Either way, you pick exactly how you want it to look.
