2091

2091 can refer to either a natural number or a calendar year. As a number, it is the integer that follows 2090 and precedes 2092. It is odd and composite, with prime factorization 3 × 17 × 41. In Roman numerals it is written as MMXCI. The divisors of 2091 include 1, 3, 17, 41, 51, 123, 697, and 2091.

As a year, 2091 CE would fall in the 21st century, specifically the 91st year of that century. In the Gregorian calendar, 2091 is not a leap year, so it would have 365 days. The year would be part of ongoing historical and cultural narratives in which near-future contexts are examined, though no single set of events is definitive for that date.

In culture and discourse, the number 2091 is sometimes used in speculative fiction and futurist discussions as a near-future setting to explore technological, environmental, or societal themes. Writers and researchers may employ the year to frame projections, fictional worlds, or scenario planning. Because it lies in the relatively near future, 2091 is often treated as a symbolic cutoff point for imagining changes that could plausibly arise from current trends, without attributing specific, real-world predictions to it.
