Each quarter begins on a Sunday and ends on a Saturday. The quarters are equal: each has exactly 91 days, 13 weeks, or 3 months. The three months in each quarter have 31, 30, and 30 days respectively. Each quarter begins with the 31-day months of January, April, July, or October.

: This day is similarly added at the end of the second quarter in
leap years. It is also dated "W" and named Leapyear Day. It is followed by Sunday, 1 July within the same year.
The World Calendar treats Worldsday and Leapyear Day as a 24-hour waiting period before resuming the calendar again. These off-calendar days, also known as "

Because any three-month sequence repeats with the same arrangement of days, the World Calendar can be expressed concisely:
Background and history
The World Calendar has its roots in the proposed calendar of the Abbot
Marco Mastrofini, a proposal to reform the Gregorian calendar year so that it would always begin on Sunday, 1 January, and would contain equal quarters of 91 days each. The 365th day of the

would be a year-end, "intercalary" and optionally holiday. In leap years, a second "intercalary day" follows Saturday, 30 June.
Around 1887 French astronomer Gaston Armelin proposed
a calendar based on this idea and roughly identical to the World Calendar.
Elisabeth Achelis

founded The World Calendar Association (TWCA) in 1930 with the goal of worldwide adoption of the World Calendar. It functioned for most of the next twenty-five years as The World Calendar Association, Inc. Throughout the 1930s, support for the concept grew in the

The League of Nations (french: link=no, Société des Nations ) was the first worldwide intergovernmental organisation whose principal mission was to maintain world peace. It was founded on 10 January 1920 by the Paris Peace Conference that ...
, the precursor of the United Nations. Achelis started the Journal of Calendar Reform in 1931, publishing it for twenty-five years, and wrote five books on the calendar concept.
Following World War II, Achelis solicited worldwide support for the World Calendar. As the movement gained international appeal with legislation introduced in the United States Congress, awaiting international decisions, Achelis accepted advice that the United Nations was the proper body to act on calendar reform. At the United Nations in 1955, the United States significantly delayed universal adoption by withholding support "unless such a reform were favoured by a substantial majority of the citizens of the United States acting through their representatives in the Congress of the United States." Also, Achelis wrote in 1955 (JCR Vol. 25, page 169), "While Affiliates and Committees have over the years and still are able to approach all branches of their governments, the Incorporated (International) Association was prevented from seeking legislation in the United States lest it lose its tax exempt status. Because of this I have been prevented from doing in my own country that which I have been urging all other Affiliates to do in theirs."
By 1956, she dissolved The World Calendar Association, Incorporated. It continued as the International World Calendar Association through the rest of the century with several directors including Molly E. Kalkstein, who is related to Achelis, and who provided the Association's first official website during her 2000–2004 tenure. The association reorganised in 2005 as The World Calendar Association, International. It was last active on 2013 as it had resumed efforts towards adoption of the World Calendar in 2017 and 2023. The World Calendar Association's last director was Wayne Edward Richardson of
Ellinwood, Kansas who died on 29 May 2020.
Reception
Benefits
As with other calendar reform proposals, supporters point out several benefits to the World Calendar over the current Gregorian calendar.
Proponents refer to its simple structure. Each day is assigned an exact, repetitive date relative to week and month. Quarterly statistics are easier to compare, since the four-quarters are the same length each year. Economic savings occur from less need to print calendars because only the year number changes. Work and school schedules do not need to unnecessarily reinvent themselves, at great expense, year after year. The World Calendar can be memorised by anyone and used similarly to a clock.
Because the World Calendar is perpetual, there is no need to churn out copies of it every year. Dates in the World Calendar occur with no more than two days difference from Gregorian calendar dates.
Religious objections
The main opponents of the World Calendar in the 20th century were leaders of religions that worship according to a seven-day cycle. For Jews, Christians and Muslims, particular days of worship are ancient and fundamental elements of their faith.
Jews observe Saturday as ''
Shabbat'', on the basis of the
Decalogue
The Ten Commandments ( Biblical Hebrew עשרת הדברים \ עֲשֶׂרֶת הַדְּבָרִים, ''aséret ha-dvarím'', lit. The Decalogue, The Ten Words, cf. Mishnaic Hebrew עשרת הדיברות \ עֲשֶׂרֶת הַדִּבְ ...

"Remember the sabbath day, to keep it holy" (Hebrew: ''zāḵōr ’eṯ-yōm haš- šabbāṯ lə- qaddəšōw'') is one of the Ten Commandments found in the Torah.
The full text of the commandment reads:

are required to worship every Saturday.
Adherents of these religions object that intercalary days are counted outside the usual seven-day week and disrupt the traditional weekly cycle. A week with a Worldsday would be eight days long. Some adherents of these religions insist that they would have to continue observing their holidays every seventh day, causing the worship days to drift by one day each year (two on a leap year), relative to the World Calendar week. The day of rest would then no longer coincide with the weekend.
These concerns played a role in the United States government's decision, at the United Nations, in 1955, not to recommend further study.
[Your Washington Review by Congressman Jerry Ford, For Release 5 May 1955]
From page 11 of an online collection of Box D1 of the Gerald R. Ford Congressional Papers at the Gerald R. Ford Presidential Library.
Jerry Ford wrote: "... I have received numerous letters in opposition to the proposed world caleridar change. I am in complete agreement with the opinions expressed in these letters and I will oppose any calendar change. The Department of State advises me that the United Nations may set up a study group on calendar reform. Secretary John Foster Dulles and our representatives at the U. N. are not in favor of this action and the United States will officially oppose setting up this U.N. study group on calendar reform. I have also been informed that our State Department will hold to that position until there is Congressional authorization for the calendar study. From my observations it seems that Congress is in no mood to tamper with the calendar."
Supporters of the World Calendar do not deny that their system is at odds with the traditions of a significant portion of the world's population, but argue that Worldsdays and Leapyear Days can be treated as "double" holidays by those who wish to maintain the seven-day week sequence.
International standards
The World Calendar, unlike some other proposals, is not compatible with the international standard
ISO 8601
ISO 8601 is an international standard covering the worldwide exchange and communication of date and time-related data. It is maintained by the Geneva-based International Organization for Standardization (ISO) and was first published in 1988, w ...
, which is based upon, but differs from, the Gregorian calendar. They differ regarding the first weekday of the week (Sunday vs. Monday), and ISO 8601 does not support intercalary dates (e.g. in notation). The World Calendar, however, modifies the Gregorian calendar less than other calendar reform proposals to achieve the sought after improvements of a simpler and perpetual calendar.
