A 13-month calendar is an intriguing alternative to the traditional 12-month Gregorian calendar. It proposes a year divided into 13 months, each consisting of 28 days, resulting in a more uniform and predictable calendar structure. This system has been suggested for its potential benefits in business, education, and daily life due to its consistency and simplicity.
What Is a 13-Month Calendar?
A 13-month calendar, often referred to as the International Fixed Calendar or the Pax Calendar, divides the year into 13 months of 28 days each, totaling 364 days. To account for the extra day in a solar year, a "Year Day" is added as a holiday at the end of the year, not belonging to any month. Leap years include an additional day, often placed after the last month.
Key Features of a 13-Month Calendar
- Uniform Months: Each month has exactly 28 days, resulting in four weeks per month.
- Consistent Weekdays: Each date falls on the same weekday every month, simplifying scheduling.
- Year Day: A day outside of the weekly cycle, often celebrated as a holiday.
- Leap Year Adjustment: An extra day added similarly to the Year Day.
Why Consider a 13-Month Calendar?
The 13-month calendar offers several advantages over the traditional system:
- Predictability: With each month having the same number of days, planning and scheduling become more straightforward.
- Simplified Accounting: Businesses benefit from consistent monthly reporting periods.
- Educational Alignment: Schools can plan academic terms more evenly.
- Cultural and Social Benefits: Regularity can enhance cultural events by aligning them with fixed dates.
How Does the 13-Month Calendar Compare to the Gregorian Calendar?

Practical Examples of 13-Month Calendar Use
While not widely adopted, the 13-month calendar has been used in various contexts:
- George Eastman, founder of Kodak, implemented it in his company from 1928 to 1989, citing benefits in business operations.
- Some educational institutions have experimented with it to create more balanced academic terms.
Challenges and Considerations
Despite its benefits, the 13-month calendar faces challenges:
