2051

2051 is a year in the Gregorian calendar. As a common year, it is not a leap year. It is used to label events, plans, and forecasts associated with the mid-21st century and can appear in historical timelines, climatology projections, and technology roadmaps. The year is sometimes discussed in forecasting and speculative fiction as part of the 2050s decade.

In mathematics, 2051 is a composite number with prime factors 7 and 293. The decimal digits are 2, 0, 5, 1, and the number is odd. In Roman numerals it is MMLI; in hexadecimal it is 0x803, and in binary it is 100000000011.

In data representation and computing, 2051 appears in contexts such as versioning or model numbers, and it serves as a concrete example of a mid-range integer. In culture, the figure is sometimes used as a distant but plausible setting year in science fiction, where it frames discussions of advanced technology, space exploration, and societal change.
