<P> The semester system divides the calendar year into two semesters of 16 to 18 weeks each , plus summer sessions of varying lengths . The two semesters together constitute 32 to 36 weeks of instruction , so that three academic quarters equal two academic semesters . Thus , academic credit earned in quarter hours converts to semester hours at 2⁄3 of its value , while credit earned in semester hours converts to quarter hours at 3 / 2 of its value . Put another way , 3 quarter hours is 2 semester hours . Most universities on the semester system have a fall semester from the day after Labor Day in September to mid-December , a spring / winter semester from late January to early May , and an optional summer session . </P>
