The secret is in what search words you use; the more parallel to your needs, the closer you get. Be specific in your search terms. A place to begin might be: free calendar formats". If that doesn't give you what you want try adding words like Excel, Word, PDF, printable, or monthly, yearly, weekly, full page, quarterly, portrait/landscape, etc. For example: "free 2008 printable Excel calendar spreadsheet" or "calendar word download 2008 annual free" are more specific. Most big sites that offer calendars will have more than one year so the " is not necessary, but a web page with 2010 in it's keywords, description and page title will frequently be closer to what you really want.
