Well, that's hard to say exactly. A story can remain relevant for a short time if it's too tied to a specific trend or moment. But if it has universal themes and timeless appeal, it could stay relevant for a very long time. Classics like 'Pride and Prejudice' are still relevant today.
It really varies. Some stories stay relevant for decades or even centuries, while others fade quickly. It depends on many factors like the quality of the writing, the themes explored, and how well it connects with readers of different eras.
The longevity of a story's relevance is quite unpredictable. It can be influenced by changes in culture, new literary movements, and shifts in reader interests. Some stories manage to stand the test of time because they touch on fundamental human experiences that never go out of style.
