Need some calendar help, please!!!

[maslex]

So I bought my new calendar for 2009 and along with it, I bought one of those wooden calendar frames to put it in but it doesn't seem to fit. The calendar seems a tad bit wider than the frame. Does anyone know how to put the calendars in this type of frame? Here's the type of frame I'm talking about.
