The Reference Shelf, Thirteen-Month Calendar is an in-depth exploration of the early 20th-century movement to overhaul the Gregorian calendar. Compiled by Julia E. Johnsen, this volume serves as a comprehensive resource for understanding the proposed transition to a thirteen-month, or fixed, calendar system-a topic of intense debate among economists, scientists, and social reformers of the era.
The work provides a structured overview of the arguments for and against calendar simplification, featuring reprints of articles, detailed briefs, and extensive bibliographies. It delves into the practical challenges of the existing calendar, such as its unequal months and shifting days of the week, while presenting the perceived benefits of a standardized system for business accounting and international commerce. The collection highlights the International Fixed Calendar proposal and other efforts to bring mathematical consistency to the measurement of time.
As a historical record, this volume captures a unique moment in modern history when global institutions reconsidered the fundamental structure of the year. It remains a valuable reference for those interested in the history of timekeeping, the evolution of social standards, and the history of public policy debate.
