Time flies means time passes quickly, often with surprise, regret, pleasure, or melancholy. In poetry, the idiom belongs naturally to themes of transience, ageing, childhood, memory, and mortality. Its winged image makes time seem alive and impossible to hold. A poet may use it in nostalgic reflection, comic conversation, or elegy, especially when happy moments vanish faster than sorrowful ones. The phrase is useful for exploring how human feeling alters the pace of time and deepens awareness of loss.

This timeless observation on transience, echoed in literature since ancient times, serves as cornerstone for carpe diem poetry, urging readers to seize fleeting moments. Professors teaching Romantic or modernist periods can highlight its use in sonnets meditating on aging and mortality. Usage tip for students: Employ rhythmic repetition or short lines to mimic speed, combining with clock or seasonal metaphors; connects to "tempus fugit" for classical depth, helping craft verses that balance melancholy with urgent celebration of life's brevity.
