2066

2066 is a year in the Gregorian calendar. It is the 66th year of the 3rd millennium and the seventh year of the 2060s decade. It is a common year, with 365 days.

As a future year, 2066 is commonly used as a reference point in planning and analysis. Projections in areas such as energy transition, climate adaptation, urban development, automation, biotechnology, and space exploration may influence conditions by that time, but specific events remain uncertain. The year can serve as a horizon for long-term policy and research goals, rather than a schedule of known happenings.

In culture and forecasting, 2066 is sometimes invoked as a plausible distant-future setting. Fiction, forecasts, and strategic studies may explore scenarios that reflect evolving technologies, demographics, and governance, while interpretations vary by author and context. The number itself is a marker for discussions about mid- to late-21st-century trends rather than a fixed historical point.
