decade
Let an agent handle decades by definition, boundaries, naming and designated international decades.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent handle decades by definition, boundaries, naming and designated international decades.
A period of ten years, either any ten-year span or a calendar decade such as the 1990s; international decades are also designated by the UN for themes.
What it is for: Grouping time for history, statistics and planning.
It can be define decade boundaries; name decades correctly; find UN international decades; compare data by decade.
Distinguishing features
Ten-year period
Calendar decades start with 0 by common convention
Ordinal decades start with 1
Used in themed international decades
