Depending on the how you want to use your calendar, you might want to show (or hide) empty days in your calendar. You can easily do this by either clicking on the blue "Hide Empty Days" link or unchecking “Show Empty Days” in the embedding configuration screen for your calendar. The only calendar view in which you can hide empty days is Event View.
