Category talk:BC year stubs

Question
What is the purpose of marking some year articles as stubs? AFAIK, year articles are simply aggregations of events that can be dated to a given year: activities, births, deaths. Some years will include fewer events than others -- & some may have none. Marking an article as a stub suggests that this article can be improved somehow, but I see no intuitive way to improve year articles. -- llywrch (talk) 19:15, 27 October 2019 (UTC)
