What is what age is a junior?

As an AI language model, I wouldn't have complete context of what a "junior" refers to. However, below are general age ranges for what age is considered a junior in various contexts:

• In education: Junior typically refers to students in their third year of high school (ages 16-17) or in their second year of college (ages 19-20).
• In sports: Junior refers to athletes who are under a certain age, which varies depending on the sport and organization. For example, in tennis, junior players are typically under age 18, while in hockey, junior players are typically under age 20.
• In the workplace: Junior may refer to entry-level employees or individuals early in their career who have less experience than senior employees. The age range for this can vary widely, depending on the industry and job.
• In society: Junior can also refer to children or young people in general. In this context, it doesn't necessarily have a specific age range.
