Smooth Calendar is a simple and good looking calendar widget. It is highly configurable and can display any number of upcoming events. You can easily adapt it to match the look of the rest of your device, such as color, font style, icon etc. Works with the sync providers on your phone and thereby supports Google Calendar, Exchange, Facebook etc.
Please note, it is a widget, this means that you need to add it to your home screen as stated in the thank you message. Giving it one star and stating in the comments that it doesn''t work is just silly.
