how many weeks is a quarter in college
Academic term The quarter system divides the calendar year into four quarters, three of which constitute a complete academic year. Quarters are typically 10 – 12 weeks long so that three quarters amount to 30 – 36 weeks of instruction. Approximately 20% of universities are on the quarter system. Most colleges that use the quarter system have a fall quarter from late September to mid-December, a winter quarter from early January to mid-March, a spring quarter from late March or early April to mid-June, and an optional summer session. Notable users of the quarter system include the University of California system (excluding Berkeley, Merced, the UCLA medical school, and all of the system's law schools), Stanford, the University of Chicago, Dartmouth College, Northwestern University, University of Washington, the University of Oregon, and DePaul University.[28][29] Union College uses a modified quarter system: fall, winter, and spring terms are each eleven weeks long; there are some summer classes, but there is no official summer quarter.[30] Because Union's calendar makes use of just three of four quarters, the three academic terms are generally (and somewhat misleadingly to outsiders) dubbed "trimesters," which they are not.[31] Another notable and somewhat unique user of the quarter system is Baylor Law School: it operates on the quarter system while the remaining colleges of Baylor University operate on the semester system.
American football Football games last for a total of 60 minutes in professional and college play and are divided into two-halves of 30 minutes and four-quarters of 15 minutes.[71][72] High school football games are 48 minutes in length with two-halves of 24 minutes and four-quarters of 12 minutes.[73] The two-halves are separated by a halftime period, and the first and third quarters are also followed by a short break.[71][72][74] Prior to the start of the game, the referee and team captains for each team meet at midfield for a coin toss. The visiting team is allowed to call 'heads' or 'tails'; the winner of the toss is allowed to decide between choosing whether to receive or kick off the ball or choosing which goal they want to defend, but they can also defer their choice until the second half. The losing team, unless the winning team decides to defer, is allowed to choose the option the winning team did not select, and receives the option to receive, kick, or select a goal to defend to begin the second half. Most teams choose to receive or defer, because choosing to kick the ball to start the game would allow the other team to choose which goal to defend.[75] Teams switch goals following the first and third quarters.[76] If a down is in progress when a quarter ends, play continues until the down is completed.[77][78][79]
