How does the perpetual calendar display today's date on the desktop?

Calendar display date can be operated as follows:

1. Click the start menu Settings Control Panel, locate and double-click the regional and language options icon.

2. In the pop-up setting window, click the Customize button on the Regional Options tab.

3. Click the Date tab in the Customize Regional Options window and add the letter "dddd" after "Long Date Format" at the bottom.

Click "OK" button to return to the control panel. Hover the mouse over the clock again, and you will be pleasantly surprised to find that the system clock can already indicate the day of the week.
