August 22
Let an agent handle August 22 as a calendar date with weekday computation, observances attributed to their traditions 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 August 22 as a calendar date with weekday computation, observances attributed to their traditions and sourced events.
August 22, day 234 (day 235 in leap years) of the year in the Gregorian calendar, with 131 days remaining in both common and leap years. August 22 is Day of the National Flag in Russia, marking the end of the August 1991 coup attempt, and the anniversary of the Battle of Bosworth Field in 1485, of the signing of the first Geneva Convention in 1864 and of the International Day Commemorating the Victims of Acts of Violence Based on Religion or Belief, observed by the UN since 2019.
What it is for: A calendar date for scheduling, holidays and anniversaries.
It can be compute its weekday in a given year; check local and international observances; find sourced historical events; schedule events.
