July
Let an agent explain July as a calendar month, relay length, position, etymology and common observances from calendar and cultural sources, and distinguish July from Julius Caesar, the Julian calendar and months in other calendars, noting that observances vary by country and year.
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 explain July as a calendar month, relay length, position, etymology and common observances from calendar and cultural sources, and distinguish July from Julius Caesar, the Julian calendar and months in other calendars, noting that observances vary by country and year.
The seventh month of the year in the Julian and Gregorian calendars, with 31 days, running from day 182 to day 212 in common years and from day 183 to day 213 in leap years, renamed from Quintilis in honour of Julius Caesar after his death in 44 BC, and containing observances such as Canada Day on 1 July, Independence Day in the United States on 4 July, Bastille Day in France on 14 July and Nelson Mandela International Day on 18 July; Earth reaches aphelion, its farthest point from the Sun, in early July.
What it is for: Organising time within the year.
It can be explain position and length; relay etymology; describe observances; distinguish related concepts.
