yearlong

"Yearlong" describes something that lasts for a whole year, all twelve months. It is not just a long time; it means the length is one full year. You might talk about a yearlong project, a yearlong exchange program, or a yearlong study. While "annual" often means something happens once every year, "yearlong" is about how long one thing continues. You would not use it for a short summer trip, but it fits something that keeps going through an entire year.

The word "yearlong" is an adjective that signifies something lasting the duration of a complete calendar year—twelve months. It emphasizes the length and continuity of an event, project, or experience. While similar to "annual" (which usually means occurring once every year), "yearlong" specifically refers to a single instance spanning 365 days (or 366 in a leap year).

You'll often encounter "yearlong" when describing commitments that require sustained effort and dedication. For example: "The research team embarked on a yearlong study of migratory bird patterns," or, "She took a yearlong sabbatical to travel the world." It suggests a significant investment of time and resources.

"Yearlong" isn't typically used for things that simply happen once a year; you wouldn't say "the Christmas celebration is yearlong" unless the party actually lasted for twelve months straight! Instead, it highlights the extended duration of a particular occurrence. A company might announce a "yearlong marketing campaign" to build brand awareness over an entire calendar cycle.

Think of it as a full orbit around the sun—that's what "yearlong" represents: a complete and substantial period of time dedicated to something specific. It's not just a long time; it's the length of a year.
