find and download an academic calendar for your college or university. for example, here is USF's 2008-2011 academic calendar. you can usually find your academic calendar by visiting your college/university's web page and searching for "academic calendar."
type in all days that your course meets. consult your academic calendar and note which days are vacation days - thanksgiving, spring break, etc.
at this point, your course calendar will look something like this:

once complete, stare a while at your course calendar. get a sense of its temporal nature. appreciate the months that your course occupies. become familiar with how many weeks your course lasts, locate the half-way point of the course, and dream about the final weeks of the course.
then, save your document, shut down your computer, and celebrate your progress.
