What's a 4-1-4 academic calendar?

I've been researching different colleges and noticed that some have a 4-1-4 academic calendar. Can someone explain how this type of calendar works and what it means for students? Thanks in advance!

A 4-1-4 academic calendar is a unique schedule followed by some colleges which consists of two regular semesters of about four months each (the first “4” and the second “4”) separated by a one-month term (the “1”). The first semester usually takes place from late August or early September until December, while the second one happens from late January to May. The one-month term, often called a January term, winter term, or intersession, typically occurs in January.

During the one-month term, students have the opportunity to take one or two intensive courses or participate in off-campus experiences, internships, or study abroad programs. This term provides students with a chance to explore unique courses, subjects, or interests beyond their traditional course load and requirements. It's a chance for students to immerse themselves in a singular experience without the distractions of a full course load, which can lead to deeper understanding and personal growth.

The 4-1-4 calendar allows students to enjoy some flexibility in their academic commitments while also staying on track to complete their degree requirements. It may be particularly appealing to students who appreciate the balance between focused, in-depth learning experiences and the curricular variety offered by regular semesters. But it's not for everyone, so make sure you're thoughtful about how you learn and grow best if you're considering applying to a school with this kind of calendar.

Best of luck with your college search!
