The response generated is correct that the Romantic Age in literature does not have fixed start and end dates. While the response notes that for English literature, the Romantic period is commonly considered to span from 1785 to 1832, we would note that .there are works of literature that fall outside of that time frame that clearly show the influence of the Romantic movement. For example, Emily Brontë’s Wuthering Heights was published in 1847 and yet has multiple elements that characterize Romantic literature, including high levels of character emotionalism and long passages describing the surrounding nature that presumably also indicate the influence of nature on the characters and story. For example, the following passage from the novel uses nature and description of the moors to set the tone for the loneliness, despair, and frequent bleakness that propel the story forward. Think of the bolded words as describing not only the surrounding nature, but a state of emotion the primary characters often feel.

My landlord halloed for me to stop ere I reached the bottom of the garden, and offered to accompany me across the moor. It was well he did, for the whole hill-back was one billowy, white ocean; the swells and falls not indicating corresponding rises and depressions in the ground: many pits, at least, were filled to a level; and entire ranges of mounds, the refuse of the quarries, blotted from the chart… guides in the dark, and also when a fall, like the present, confounded the deep swamps on either hand with the firmer path: but, excepting a dirty dot pointing up here and there, all traces of their existence had vanished:

Moreover, the brooding Heathcliff is often cited as an example of a Byronic hero, with Lord Byron frequently cited as a key poet in the literary Romantic movement. That a piece of literature falls outside the dates given for the start and end of period makes sense, as artists are often influenced by the works and ideas of others around them at the time or who preceded them.
