Looks like Android Agenda Widget to me. It's what I have, and my set up looks pretty similar to that. You can do all sorts of customization on the widget.
Anyway you could possibly show a screen shot of it? I'm just curious to see if it's close and what not.
I definitely really like the layout and how it looks as far as the screen shot I provided. The one I have on my phone now is alright but I like how you can see Today's and tomorrow's and etc if that makes sense.
