mid22nd

Mid22nd is an informal label used to designate the middle portion of the twenty-second century, the years roughly centered on 2150 in the Gregorian calendar. The term is a neologism formed by combining mid with 22nd, and in some online glossaries and worldbuilding wikis it appears written as mid22nd without spaces.

There is no standardized window for mid22nd. Different projects may adopt slightly different boundaries, but a common convention places the period roughly between the 2140s and 2160s, with 2150 serving as the approximate central anchor. The lack of formal definition means the term functions more as a convenient shorthand than as a precise chronological designation.

Usage and contexts are predominantly in speculative fiction timelines, futurist essays, and community-curated worldbuilding repositories. It is not an official historical or scholarly term, and in formal discourse writers typically refer to “the mid-22nd century” rather than the compact form mid22nd. The shorthand is most useful for concise planning or narrative pacing in fictional worlds and long-range scenario analyses.

Rationale for use includes the desire for brevity in timelines and ease of reference when discussing long-range trends (technology, geopolitics, climate, society). Critics note that compact labels can sow ambiguity given varying calendar conventions and cultural interpretations of century boundaries; without explicit dates, readers may misinterpret the intended time frame. Overall, mid22nd remains a niche, informal descriptor within speculative and worldbuilding contexts.
