Gunian

Gunian is a fictional unit of time, primarily used in the science fiction franchise Dune, created by Frank Herbert. A Gunian is defined as roughly equivalent to one Earth year. The term is used throughout the series to denote periods of time, often in relation to lifespans, historical events, or projected futures. The adoption of "Gunian" allows the narrative to maintain a sense of temporal grounding for the reader while also emphasizing the distinct cultural and historical context of the Dune universe, which spans millennia. The term helps to establish a sense of familiarity despite the vast differences in technology, societal structures, and environments presented in the books.
