Armelin's Calendar
Armelin's calendar was developed around 1887 by French astronomer , who developed a twelve-month calendar in which the year of 364 days was divided into four equal quarters of 91 days. Armelin's calendar proposal was discussed chiefly under the auspices of the Société astronomique de France in 1887 and recently in the French Academy of Sciences. Structure # The year is divided into four quarters of three months each, and the arrangements for the first quarter repeat in each of the other quarters. The first and second month of each quarter have thirty days, and the third month 31 days. This accounts for 91 days in each quarter, or 364 days in all. # The remaining day in ordinary years is "New Year's Day". It is given no other descriptive title. It does not belong to any week or any month. It begins the year. January 1 is the day following New Year's Day. # The 366th day of leap year is likewise an extra day, bearing an appropriate descriptive name, perhaps ...

Calendar
A calendar is a system of organizing days. This is done by giving names to periods of time, typically days, weeks, months and years. A date is the designation of a single and specific day within such a system. A calendar is also a physical record (often paper) of such a system. A calendar can also mean a list of planned events, such as a court calendar or a partly or fully chronological list of documents, such as a calendar of wills. Periods in a calendar (such as years and months) are usually, though not necessarily, synchronized with the cycle of the sun or the moon. The most common type of pre-modern calendar was the lunisolar calendar, a lunar calendar that occasionally adds one intercalary month to remain synchronized with the solar year over the long term. Etymology The term ''calendar'' is taken from , the term for the first day of the month in the Roman calendar, related to the verb 'to call out', referring to the "calling" of the new moon when it was first se ...

Académie Des Sciences
The French Academy of Sciences (French: ''Académie des sciences'') is a learned society, founded in 1666 by Louis XIV at the suggestion of Jean-Baptiste Colbert, to encourage and protect the spirit of French scientific research. It was at the forefront of scientific developments in Europe in the 17th and 18th centuries, and is one of the earliest Academies of Sciences. Currently headed by Patrick Flandrin (President of the Academy), it is one of the five Academies of the Institut de France. History The Academy of Sciences traces its origin to Colbert's plan to create a general academy. He chose a small group of scholars who met on 22 December 1666 in the King's library, near the present-day Bibliothèque Nationals, and thereafter held twice-weekly working meetings there in the two rooms assigned to the group. The first 30 years of the Academy's existence were relatively informal, since no statutes had as yet been laid down for the institution. In contrast to its British ...

Europe
Europe is a large peninsula conventionally considered a continent in its own right because of its great physical size and the weight of its history and traditions.

Perennial Calendar
A perennial calendar is a calendar that applies to any year, keeping the same Calendar date, dates, weekdays and other features. Perennial calendar systems differ from most widely used calendars which are annual calendars. Annual calendars include features particular to the year represented, and expire at the year's end. A perennial calendar differs also from a perpetual calendar, which is a tool or reference to compute the weekdays of dates for any given year, or for representing a wide range of annual calendars. For example, most representations of the Gregorian calendar year include weekdays and are therefore annual calendars, because the weekdays of its dates vary from year to year. For this reason, proposals to perennialize the Gregorian calendar typically introduce one or another scheme for fixing its dates on the same weekdays every year. History and background The term ''perennial calendar'' appeared as early as 1824, in the title of Thomas Ignatius Maria Forster's ''Pere ...

Thanksgiving Day
Thanksgiving is a national holiday celebrated on various dates in the United States, Canada, Grenada, Saint Lucia, Liberia, and unofficially in countries like Brazil and Philippines. It is also observed in the Netherlander town of Leiden and the Australian territory of Norfolk Island. It began as a day of giving thanks for the blessings of the harvest and of the preceding year. (Similarly named harvest festival holidays occur throughout the world during autumn, including in Germany and Japan). Thanksgiving is celebrated on the second Monday of October in Canada and on the fourth Thursday of November in the United States and around the same part of the year in other places. Although Thanksgiving has historical roots in religious and cultural traditions, it has long been celebrated as a secular holiday as well. History Prayers of thanks and special thanksgiving ceremonies are common among most religions after harvests and at other times of the year. The Thanksgiving holida ...

Sabbath In Seventh-day Churches
The seventh-day Sabbath, observed from Friday evening to Saturday evening, is an important part of the beliefs and practices of seventh-day churches. These churches emphasize biblical references such as the ancient Hebrew practice of beginning a day at sundown, and the Genesis creation narrative wherein an "evening and morning" established a day, predating the giving of the Ten Commandments (thus the command to "remember" the sabbath). They hold that the Old and New Testament show no variation in the doctrine of the Sabbath on the seventh day. Saturday, or the seventh day in the weekly cycle, is the only day in all of scripture designated using the term Sabbath. The seventh day of the week is recognized as Sabbath in many languages, calendars, and doctrines, including those of Catholic, Lutheran, and Orthodox churches. It is still observed in modern Judaism in relation to Mosaic Law. In addition, the Orthodox Tewahedo Churches uphold Sabbatarianism, observing the Sabbath on Satur ...

World Calendar
The World Calendar is a proposed reform of the Gregorian calendar created by Elisabeth Achelis of Brooklyn, New York in 1930. Features The World Calendar is a 12-month, perennial calendar with equal quarters. 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. The World Calendar also has the following two additional days to maintain the same new year days as the Gregorian calendar. ; Worldsday : The last day of the year following Saturday 30 December. This additional day is dated "W" and named Worldsday, a year-end world holiday. It is followed by Sunday, 1 January in the new year. ; Leapyear Day : 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 ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Invariable Calendar
In April 1900, Professor L. A. Grosclaude of Geneva proposed the Invariable Calendar, New Era Calendar, or Normal Calendar with 12 months and four 91-day quarters of exactly 13 weeks. An additional day, termed New Year's Day, that was not any day of the week and not part of any month, would occur between December 31 and January 1. Another such day is inserted between June 31 and July 1 on leap years. This model would be a Perennial Calendar, perennial calendar, with each date occurring perennially on the same day of the week. Grosclaude lists many business advantages to this. Three monthly days important to businesses, the 1st, 15th, and 30th would always occur on the same 3 days of the week, respectively, and additionally would never occur on a Sunday, for example. It became the model for The World Calendar, promoted by Elisabeth Acheils anThe World Calendar Associationsince 1930.
