A "year career" is a term used to describe an extended period of time, typically measured in years, during which someone pursues a particular profession or engages in a specific activity as their primary source of income. In other words, it refers to the duration of one's working life in a single field or industry. The phrase can also be used more broadly to describe an extended period of time spent doing something that is not necessarily related to work, such as pursuing education or training for personal development.
