While there is no one-size-fits-all answer, a typical full-time K-12 school year in the United States usually consists of 37-40 weeks. However, this duration can vary significantly depending on factors such as location, district policies, and state-specific regulations. For instance, some schools may operate on a 38-week calendar with one longer summer break, while others might have two shorter breaks throughout the year. Meanwhile, higher education institutions generally follow a standard 15-16 week academic term with four terms per year, resulting in approximately 60-64 weeks per academic year. It's worth noting that these periods can be subject to change due to factors like weather conditions, state budget constraints, or shifting educational priorities.
