From its beginnings as the Storrs Agricultural School in 1881, Connecticut Agricultural College operated on a trimester system, with fall, winter, and spring terms. That came to an end in 1914, when a meeting of the faculty (this was well before creation of the University Senate), voted to change to a two semester academic calendar. The three semester system had terms of uneven duration – a 15 week fall term, 11 week winter term, and 13 week spring term. After the change to two semesters, the calendar was virtually unchanged for decades. Until 1972, the fall semester began in late September and ended by mid-January. Students went home for the Christmas/New Year break, came back for final exams, then went home again for semester break.
