I'm assuming you're looking for the monthly planner view that actually shows events and not just indicators? Try calendar widgets suite or business calendar 2 planner. Unfortunately both are ad-supported (anything designed explicitly to show local personal information shouldn't go online IMHO), but there's a paid version as well. There's a couple other apps that have similar looking widgets as well, you might find more by searching for monthly planner widgets, not calendar widgets. It might also be possible to find one using a week toolkit (I used Zooper in the past, but I think it's pretty dead now; not sure what's replaced it).
