The book now includes algorithmic descriptions of nearly forty calendars: the Gregorian, ISO, Icelandic, Egyptian, Armenian, Julian, Coptic, Ethiopic, Akan, Islamic (arithmetic and astro- nomical forms), Saudi Arabian, Persian (arithmetic and astronomical), Bahá’í (arithmetic and astronomical), French Revolutionary (arithmetic and astronomical), Babylonian, Hebrew (arithmetic and astronomical), Samaritan, Mayan (long count, haab, and tzolkin), Aztec (xihuitl and tonalpohualli), Balinese Pawukon, Chinese, Japanese, Korean, Vietnamese, Hindu (old arithmetic and medieval astronomical, both solar and lunisolar), and Tibetan Phug-lugs. It also includes information on major holidays and on different methods of keeping time. The necessary astronom- ical functions have been rewritten to produce more accurate results and to include calculations of moonrise and moonset. The authors frame the calendars of the world in a completely algorithmic form, allowing easy conversion among these calendars and the determination of secular and religious holidays. Lisp code for all the algorithms is available in machine- readable form. Edward M. Reingold is Professor of Computer Science at the Illinois Institute of Technology.

  • CALENDARS by David Le Conte
    CALENDARS by David Le Conte This article was published in two parts, in Sagittarius (the newsletter of La Société Guernesiaise Astronomy Section), in July/August and September/October 1997. It was based on a talk given by the author to the Astronomy Section on 20 May 1997. It has been slightly updated to the date of this transcript, December 2007. Part 1 What date is it? That depends on the calendar used:- Gregorian calendar: 1997 May 20 Julian calendar: 1997 May 7 Jewish calendar: 5757 Iyyar 13 Islamic Calendar: 1418 Muharaim 13 Persian Calendar: 1376 Ordibehesht 30 Chinese Calendar: Shengxiao (Ox) Xin-You 14 French Rev Calendar: 205, Décade I Mayan Calendar: Long count 12.19.4.3.4 tzolkin = 2 Kan; haab = 2 Zip Ethiopic Calendar: 1990 Genbot 13 Coptic Calendar: 1713 Bashans 12 Julian Day: 2450589 Modified Julian Date: 50589 Day number: 140 Julian Day at 8.00 pm BST: 2450589.292 First, let us note the difference between calendars and time-keeping. The calendar deals with intervals of at least one day, while time-keeping deals with intervals less than a day. Calendars are based on astronomical movements, but they are primarily for social rather than scientific purposes. They are intended to satisfy the needs of society, for example in matters such as: agriculture, hunting. migration, religious and civil events. However, it has also been said that they do provide a link between man and the cosmos. There are about 40 calendars now in use. and there are many historical ones. In this article we will consider six principal calendars still in use, relating them to their historical background and astronomical foundation.

  • One World: One Calendar
    One World: One Calendar By eLaine Vornholt Laura Lee Vornholt-Jones The desire to reform the Gregorian calendar has never died out. In 1975, when Jimmy Carter was running for president of the United States, he stated that he was running for peace in the Middle East and The World Calendar. Currently, there is a growing movement to implement The World Calendar in 2012. The World Calendar Association, International, continues the push for calendar reform. Clearly stated on its home page: During the first half of last century, recognition of the need for a user-friendlier successor to the Gregorian calendar prompted world-wide study. It identified The World Calendar as the best probable choice. A well-documented attempt to make the change followed, but was not completed. In 2008, The World Calendar in 2012 continues to unfold as a multi-level demonstration that the current, nearly unanimous Gregorian calendar, as we know and ignore it, quietly stifles (smothers/chokes) potential.1 While Judeo-Christian traditionalists were able to defeat the earlier calendar reforms of the 18th and 20th centuries, current developments in the world economic situation would seem to indicate that the reform may be passed this time. The very simplicity of The World Calendar is one of its main attractions to financial and banking institutions. Standardizing the year into uniform quarters would have great economic benefits. Right now, months and quarters in the Gregorian year vary in length. On The World Calendar, each quarter would be identical to all the others: January, April, July and October would all start on Sunday.

  • Welcome to the Source of Data on Calendars
    19/04/2019 Calendopaedia - The Encyclopaedia of Calendars Welcome to THE source of data on calendars. I recommend that you start by looking at the Comparison of Calendars. Alternatively you could choose from one of these pull-down meus then click 'Go'. Choose a calendar :- Go or Choose a topic :- Go Since the dawn of civilisation man has kept track of time by use of the sun, the moon, and the stars. Man noticed that time could be broken up into units of the day (the time taken for the earth to rotate once on its axis), the month (the time taken for the moon to orbit the earth) and the year (the time taken for the earth to orbit the sun). This information was needed so as to know when to plant crops and when to hold religious ceremonies. The problems were that a month is not made up of an integral number of days, a year is not made of an integral number of months and neither is a year made up of an integral number of days. This caused man to use his ingenuity to overcome these problems and produce a calendar which enabled him to keep track of time. The ways in which these problems were tackled down the centuries and across the world is the subject of this Web site. It is recommended that you start by looking at the Comparison of Calendars. This page was produced by Michael Astbury. Thanks to all the reference sources which I have quoted (too many to list them all) and to all the friends who have contributed to these pages in so many ways.

  • The Martian Time Poll: One Martian Year of Data
    The Martian Time Poll: One Martian Year Of Data Thomas Gangale; Marilyn Dudley-Rowley [2000] Abstract The design of a Martian time-keeping system must be as much a social construct as an astronomical one if it is to gain wide acceptance within the Martian community. Not only must such a system accurately mark the passage of the Martian diurnal and annual cycles; it must also incorporate features that satisfy human social needs. What kind of a clock and calendar do Martians want? The Martian Time Web Site began conducting an on-line poll in September 1998. The Martian Time Poll consists of 25 questions on the basic elements of Martian time-keeping. The results of the first Martian year of data are reported and discussed. Introduction As we humans establish ourselves as a multiplanetary species, spreading throughout the Solar System during this new century, we will leave behind the 24-hour day and the 365-day year. These are cycles that are peculiar to Earth, and as a product of billions of years of evolution on this planet, we are designed to operate by them. Humans will have no use for diurnal periods that are hundreds of hours long. Similarly, years of 12 or 29 times the duration of the terrestrial year (the orbital periods of Jupiter and Saturn, respectively) will be of no practical use in human affairs. We define a standard unit, the second, in as abstract a way as possible for the physical sciences, but time is a social measurement, first and foremost. We awaken, we work, we eat, and we sleep.

  • God's World Calendar
    GOD’S WORLD CALENDAR– WITH THE FACTS Creation Calendar is the oldest calendar in the world. It dates back to the first week of Creation. It’s Biblical, astronomical and scientific. Thus, we are faced with the task of establishing the beginning of the calendar, for it is an instrument of time, by which events are recorded. In order to do so, we must go back to the oldest record known to man, which is Genesis of the Holy Bible, and it states, “In the beginning God created the heaven and the earth. And the earth was without form, and void, and darkness was upon the face of the deep. And the Spirit of God moved upon the face of the waters. And God said, Let there be light: and there was light. And God saw the light, that it was good: and God divided the light from the darkness. And God called the light Day, and the darkness he call Night. And the evening and the morning were the first day.” Genesis 1:1-5. Thus we have the beginning of time on this earth. Moving on to Genesis 1:14-19, we quickly see that Creation Calendar was created beginning on the fourth day of the week of creation, Wednesday, making Sunday the first day of the week, and bound the time by astronomical law. It is with God’s astronomical law that we prove the authenticity of Creation Calendar, showing it to be the oldest calendar in the world created by (YHWH), the Almighty God, Creator of heaven and earth.

Baha´’ı´ Calendar and Rhythms of Worship The Baha´’ı´ calendar charts physical time, as do all calendrical systems, yet is addi- tionally designed to inspire spiritual progress by associating time with the cultiva- tion of human nobility. The precise name for the Baha´’ı´ calendar is the Badı´‘ (“Unique” or “Wondrous”) calendar. It originated with Sayyid ‘Alı´-Muhammad ˙ of Shiraz (1819–1850), entitled the Ba´b (“the Gate”), who founded the Ba´bı´ reli- gion, soon superseded by the Baha´’ı´ Faith, established by Mı´rza´ Husayn-‘Alı´ Nu´rı´ ˙ (1817–1892), known as Baha´’u’lla´h (a spiritual title meaning the “Splendor [or “Glory”] of God”). By adopting and modifying the Badı´‘ calendar for use by the Baha´’ı´ community, Baha´’u’lla´h gave it formal sanction. Time is invested with spiritual significance by the naming of weekdays, days of the month, months, years, and cycles of years after godly perfections that can be translated into goodly virtues, such as “Beauty” (Jama´l) “Knowledge” (‘Ilm), “Honor” (Sharaf), and “Grandeur” (‘Azamat), which are names of 4 of the 19 ˙ Baha´’ı´ months.

  • Proposed Utopian Calendar. Joseph G. Collins. Los Angeles, Calif. 1939
    Proposed Utopian calendar. Joseph G. Collins. Los Angeles, Calif. 1939. Forty-one years ago I became interested in a world calendar. Thirty-six years ago I completed a 12- month calendar and about the same time completed a 13-month calendar, naming the extra month “Sol”, which is placed between August and September, two weeks on each side of the equinox, making 26 weeks on each side. My calendar makes a perfect dial for a world clock, with each day, hour, minute and second registered in its proper place. I use marine time calculation, which shows 24 hours on the clock, noon being at 12 and the end of night being at 24 o'clock, doing away with A.M. and P.M. This calendar fits both the northern and southern hemispheres. When we in the northern hemisphere have our longest day of the year, the southern hemisphere has its shortest, and vice-versa. In my proposed calendar the year begins at the vernal equinox, at zero, where there is neither longitude nor latitude. New Year's Day commences six hours before sunup and the sun rises in the due East at 6:00 A.M. and sets at 6:00 P.M. in the due West, the day ending at 12:00 at night. The earth moves to the left, contrary to clockwise. New Year's Day is always March 1st in Easter Sunday (Son's Day). Spring ends June 8th at 7:00 A.M., 27 minutes and 11½ seconds, which is one-fourth of 365 days, five hours, 48 minutes and 46 seconds, the full year.

I speak of Thanksgiving, Christmas and now New Years. Only one of the three has significant Spiritual meaning, that being Christmas. I said three Christian holidays because Thanksgiving to the Christian is associated with our thankfulness for God's abundant blessings. New Years may be considers a Christian because not all religions recognize it as a New Year. NEW YEAR What marks or makes or makes it a new year? Time, solar system? You make it a new year. Is it the calendar? Jewish, Roman or Gregorian? There are over 100 different calendars in the world.
