- Not widely adopted
The 13-month calendar offers several advantages over the traditional 12-month calendar, but it has not gained widespread adoption due to various reasons, including resistance to change and the complexity of implementing a new calendar system.
Proposed by Moses B. Cotsworth
The idea of a 13-month calendar gained significant traction in the early 20th century thanks to the efforts of Moses B. Cotsworth, an American inventor and engineer. Cotsworth, who held over 80 patents in his lifetime, was fascinated by the inefficiencies of the Gregorian calendar, the calendar most widely used in the world today.
Cotsworth believed that the 12-month calendar, with its varying month lengths and the need for leap years, was outdated and cumbersome. He proposed a 13-month calendar as a more rational and practical alternative.
Cotsworth's 13-month calendar, which he called the "Cotsworth Plan," consisted of 13 months, each with 28 days. This resulted in a total of 364 days, with an extra day added every five or six years to account for the Earth's actual solar year length. Cotsworth argued that this system would eliminate the need for leap years and make date calculations much simpler.
Cotsworth actively promoted his calendar plan, writing articles, giving lectures, and lobbying government officials. He established the World Calendar Association in 1930 to garner support for the 13-month calendar and advocate for its adoption.
Despite Cotsworth's efforts and the support of various organizations and individuals, the 13-month calendar failed to gain widespread acceptance. The Gregorian calendar, with its deeply ingrained traditions and cultural significance, proved too difficult to replace.
Consists of 13 months
The 13-month calendar, as proposed by Moses Cotsworth, consists of 13 months, each with 28 days. This structure offers several advantages over the traditional 12-month calendar.
Firstly, it eliminates the need for leap years. In the Gregorian calendar, leap years are necessary to adjust for the Earth's actual solar year length, which is approximately 365.242 days. This results in an extra day being added to February every four years. However, in the 13-month calendar, the extra days are evenly distributed across the year, with each month having 28 days. This makes date calculations much simpler and reduces the potential for errors.
Secondly, the 13-month calendar aligns more closely with the Earth's natural cycles. The 12-month calendar is based on the lunar cycle, with each month representing one complete cycle of the moon around the Earth. However, the Earth's orbit around the sun (the solar year) is slightly longer than 12 lunar cycles. This misalignment leads to the seasons gradually shifting over time in the Gregorian calendar. In contrast, the 13-month calendar, with its 28-day months, more accurately reflects the Earth's solar year and keeps the seasons aligned with the calendar months.
Thirdly, the 13-month calendar offers improved scheduling and resource allocation. With its consistent 28-day month lengths, the 13-month calendar makes it easier to plan and schedule events, activities, and tasks. Additionally, the elimination of leap years removes the irregularities associated with February in the Gregorian calendar, leading to more efficient resource allocation and utilization.
Overall, the 13-month calendar's structure, with its 13 months and 28-day lengths, provides a more logical, consistent, and user-friendly system for measuring time and organizing activities.
