Saturday
Let an agent handle Saturday as a weekday with numbering conventions, legal and working-time rules and named occurrences.
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 Saturday as a weekday with numbering conventions, legal and working-time rules and named occurrences.
The day of the week between Friday and Sunday, day 6 in ISO 8601 weeks; part of the weekend in many countries, a working day in others, and the Sabbath in Judaism.
What it is for: Scheduling, work patterns, trading hours and observances.
It can be schedule around it; number it, as day 6 in ISO 8601; apply working-time and trading rules to it; identify named occurrences.
Distinguishing features
Day 6 in ISO weeks; numbering differs in other conventions
Working day or weekend depending on country
Named occurrences carry commercial or religious meaning
Specific dates in the registry aliases are instances, not the weekday
What it looks like
Not a thing to see; a day on the calendar.
How it is recognised

ISO 8601 weekday number 6
Named occurrences such as Holy Saturday and Super Saturday
