  • Gangale 2000 the MARTIAN TIME POLL: ONE MARTIAN YEAR OF
    Gangale_2000 THE MARTIAN TIME POLL: ONE MARTIAN YEAR OF DATA Thomas Gangale* And Marilyn Dudley-Rowley** ABSTRACT The design of a Martian timekeeping 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 online poll in September 1998. The Martian Time Poll consists of 25 questions on the basic elements of Martian timekeeping. The results of the first Martian year of data are reported and discussed. KEYWORDS: timekeeping, Mars calendars, Mars clocks, measurement as social construct. 1. 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.

  • How Long Is a Year.Pdf
    How Long Is A Year? Dr. Bryan Mendez Space Sciences Laboratory UC Berkeley Keeping Time The basic unit of time is a Day. Different starting points: • Sunrise, • Noon, • Sunset, • Midnight tied to the Sun’s motion. Universal Time uses midnight as the starting point of a day. Length: sunrise to sunrise, sunset to sunset? Day Noon to noon – The seasonal motion of the Sun changes its rise and set times, so sunrise to sunrise would be a variable measure. Noon to noon is far more constant. Noon: time of the Sun’s transit of the meridian Stellarium View and measure a day Day Aday is caused by Earth’s motion: spinning on an axis and orbiting around the Sun. Earth’s spin is very regular (daily variations on the order of a few milliseconds, due to internal rearrangement of Earth’s mass and external gravitational forces primarily from the Moon and Sun). Synodic Day Noon to noon = synodic or solar day (point 1 to 3). This is not the time for one complete spin of Earth (1 to 2). Because Earth also orbits at the same time as it is spinning, it takes a little extra time for the Sun to come back to noon after one complete spin. Because the orbit is elliptical, when Earth is closest to the Sun it is moving faster, and it takes longer to bring the Sun back around to noon. When Earth is farther it moves slower and it takes less time to rotate the Sun back to noon. Mean Solar Day is an average of the amount time it takes to go from noon to noon throughout an orbit = 24 Hours Real solar day varies by up to 30 seconds depending on the time of year.

  • The Calculation of Doomsday Based on Anno Domini
    SCIENTIFIC CULTURE, Vol. 1, No. 2, (2015), pp. 22-32 Copyright © 2015 SC Open Access. Printed in Greece. All Rights Reserved. The calculation of doomsday based on Anno Domini Sepp Rothwangl Waldwirtschaft Hubertushof Scheibsgraben 49, A-8661 Wartberg, Astria (CALENdeRsign.com;[email protected]) Received: 10/01/2015 Accepted: 15/02/2015 ABSTRACT Anno Domini, or the year Christ’s birth, was an invention made some 1400 years ago by Dionysius Exiguus, who adjusted a new Easter Computus in order to avert end time fever with the pretext to solve a dispute upon the correct date of Easter. Right at the beginning of Christianity, early Christians expected in the near future the return of Christ, which was associated with the end of the world, together with the Seventh Day of the Lord. Such a scenario ocurred already in the cosmic year Anno Mundi (AM) 6,000 based upon a teleological concept by interpreting the Bible. AM produced a calendrical end time with its year 6000 due to equating the Six Days of Genesis with the verse of the Bible saying one Day of the Lord was the same as 1000 years of mankind. To combat the end of the world fever caused by this time concept at the beginning of the 6th century Dionysius Exiguus created a new temporal hinge point for counting the years: Anno Domini. Obviously this chronology is not in harmony with ancient historical works, as even former Pope Benedict XVI recognized, but is an end time prophecy by interpreting the Gospel, the Apocalypse, the scientific cosmology of antiquity, and astronomical values.

  • The History of School and Summer Vacation
    Journal of Inquiry & Action in Education, 5(1), 2012 The History of School and Summer Vacation James Pedersen Seton Hall University For more than 100 years the public school system has been the foundation of our society. Millions of our nation’s citizens have moved through the primary, middle and secondary schools which, although they vary slightly from region to region, provided a shared experience and are a part of Americana. History tells us the reasons that school systems used only a 10 month calendar were due to agrarian needs, but in recent years this rationale does not seem as applicable. In light of global competition and America’s consistently poor international rankings, it would seem logical conclusion to extend the school year to increase instructional time. But the move to year-round schooling isn’t so easy, nor is it unanimously embraced by parents, community members, businesses or politicians.

Thinking about the Unthinkable Of all the unexamined assumptions and criteria upon which we base and gauge our daily lives as human beings on planet Earth, by far the greatest and most profoundly unquestioned is the instrument and institution known as the Gregorian Calendar. A calendar, any calendar, is commonly understood as a system for dividing time over extended periods. A day is the base unit of a calendar, and the solar year is the base extended period. The length of the solar year is currently reckoned at 365.242199 days. The Gregorian calendar divides this duration into twelve uneven months – four months of 30 days, seven of 31 days, and one of 28 days.

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.

  • 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.
