Secret societies organized members by natural calendrical rhythms for hierarchy

Evidence

A secret political society under Louis Philippe called itself “The Seasons.” Six members under the leadership of a seventh, who was called Sunday, formed a week; four weeks, a month; three months, a season; and four seasons, the highest unit that stood under a supreme commander. — Georg Simmel, The Sociology of Georg Simmel, 4776

Categorization

• CANDY: A secret society that called its leader ‘Sunday’ and organized into weeks, months, and seasons is a delightfully concrete trivia nugget.
• FICTION: A real hierarchical secret society modeled on the calendar is ready source material for worldbuilding or plot.
