Every so often students may need to speak to professors outside of class for extra help on an assignment or to help clarify information. Because professors have many commitments and they know students have questions, professors designate times when they will be available to students. These hours should be on the class syllabus and on the professor's office door.
Office hours are your instructor's/TA's time to meet with you about your courses or concerns. They usually set up their office hours at the beginning of the semester so that you know when they are available to talk. Many TAs are willing to arrange appointments if you can't make it to their pre-set office hours.
