January 2
Let an agent handle January 2 as a calendar date with weekday computation, observances and sourced events.
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 January 2 as a calendar date with weekday computation, observances and sourced events.
The second day of the year in the Gregorian calendar, with 363 days remaining (364 in leap years); a public holiday in some places, for example as an extra New Year holiday in Scotland and New Zealand.
What it is for: A calendar date for scheduling, holidays and anniversaries.
It can be compute its weekday in a given year; check whether it is a holiday locally; find sourced historical events; schedule events.
