How many times did you forget the current month? Not so many. Do you really need it on a widget?
This calendar widget shows you just the month day and week day, because these are the most changing date information. It is simple and clear, like the iPhone one. Working days are shown on blue and sundays on red. Touch it to go to your calendar. Week day names are from your own device, not from the widget, so do not worry about translations.
The date is updated frequently to show ALWAYS the correct date even if you just changed it. Not all widgets in the market can say this.
Remember: This App is a widget, not a regular App. So you need to manually add the widget to your home screen.
Now you can choose which app is launched when you touch the widget!
