December
Let an agent explain December as a calendar month, relay length, position, astronomy, etymology and common observances from calendar and cultural sources, and distinguish December from the December solstice, the holiday season as a cultural period 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 December as a calendar month, relay length, position, astronomy, etymology and common observances from calendar and cultural sources, and distinguish December from the December solstice, the holiday season as a cultural period and months in other calendars, noting that observances vary by country and year.
The twelfth and last month of the year in the Julian and Gregorian calendars, with 31 days, running from day 335 to day 365 in common years and from day 336 to day 366 in leap years, named from Latin decem, ten, because it was the tenth month of the early Roman calendar, containing the December solstice around 21 or 22 December, the start of astronomical winter in the Northern Hemisphere and summer in the Southern Hemisphere, and observances such as Human Rights Day on 10 December, Christmas on 25 December, New Year s Eve on 31 December and in many years Hanukkah, whose dates follow the Hebrew calendar.
What it is for: Organising time within the year.
It can be explain position and length; relay astronomy and etymology; describe observances; distinguish related concepts.
