Calendars – Why They Can Be A Bit Out

Tuesday, July 13th, 2010

Thousands of years ago, ancient Greek astronomers calculated that the direction of the Earth’s axis is constantly, albeit in a very slow way, shifting in a regular pattern. The variation is very similar to the way a spinning top slowly leans one way and then another as it slows down. It is a wobble that happens as its axis changes direction.

This odd movement of the planet is due to a couple of factors, the most important of which is something called ‘precession’. Precession arises from the fact that the Earth is not a perfect sphere. It is in fact about twenty-seven miles longer around the Equator that it is around the Poles. The Earth then is oblate, or fat around the middle like middle-aged spread, but it is due to the rotation not to its age.

If you imagine the Earth with its Poles off centre. Then rotate that image and you will find that any point, except the very centre of the axis, will travel in a circle. But very, very slowly. So slowly that it takes 26,000 years to travel full circle and get back to where it started from.

This point then, any point you choose, is very gradually shifting its location in relation to the stars because the axis is gyrating too. The result of this is that, what we call the North Star (formally known as Polaris, which is in fact one degree off true North) will not be over our North Pole one day. In fact, by about 15,000 AD, Vega will be almost above the North Pole, although it will be about four degrees off true North. But even this will not endure, and by 28,000 AD, Polaris will be back above where it is nowadays.

One of the effects of the precession is that seasons vary. They modify the dates that they take place, so that Summer could come earlier or later. The amazing thing about our calendar is that it is corrected for that (with the leap year). If it were not, the vernal or Spring equinox would shift over 13,000 years from March 21st to September 21st., which is the date of the autumnal equinox, precisely half a year later.

It is for this reason that the precession of the Earth is generally referred to as the “Precession of the Equinoxes”. Although the precession of the equinoxes is very slow, it can be readily observed. The correct year of 325.25 days is the length of time from one vernal equinox to the next vernal equinox, however, it takes 20 minutes and 24 seconds longer for the Sun to appear in precisely the same place with relation to the stars behind it over the same period. This is why accurate star maps have to be stamped with the exact time and date to which they refer.

Calendars And How To Appreciate Them

Wednesday, July 7th, 2010

The calendar is such a routine, ordinary thing, but how much do you actually know about the working of it. Why is it like that?

A DAY: The Earth rotates at a reasonably steady pace about the imaginary line running between the North and South Poles called the Earth’s Axis. The time it takes to revolve once is called a ‘rotation’ and this takes just under twenty-four hours. Nevertheless, because the Earth is continuously travelling around the Sun, the precise time from noon one day to noon the next is 3 minutes 56 seconds longer and this makes a day almost exactly twenty-four hours in length.

The actual time from noon to noon differs depending where the Earth is on its celestial course around the Sun, but if you average the days in a year out, it comes to precisely twenty-four hours.

A YEAR: All nine planets in our solar system travel around the Sun in almost perfectly circular routes called orbits. Each trip around the Sun is called a revolution and all the planets revolve around the Sun in the same direction. The direction the Earth takes can be verified by noting its location against the background stars.

In view of the fact that you cannot see the Sun and the stars at the same time, it is necessary to note the position of the Sun in the morning and the see which stars come out there in the night. You will see that the Sun seems to pass through the twelve constellations of the zodiac during a year.

Earth’s journey around the Sun, which seems like the Sun travelling through the zodiac takes about 365.25 days. This is different from year to year, so astronomers add or delete a second in some years to keep their time accurate with the Earth’s motion.

THE SEASONS: The seasons indicate the variation in the pattern of daylight over the course of a year. Because the Earth is tilted off centre, different parts of it get different amounts of sunlight on different stages of its path around the Sun, a path that we call a year. So, between about the 21st September and late March, the Earth’s Northern Hemisphere is tilted away from the Sun, which creates Autumn and Winter, giving less than twelve hours of daylight per day.

From April to the 20th September, the Northern Hemisphere receives more than twelve hours of daylight a day, producing Spring and Summer. The exact opposite occurs in the Southern Hemisphere.

The Equinoxes take place at the points in the year when there is exactly twelve hours of sunlight and darkness in the day. So, the vernal or Spring equinox is on or around the 21st March and the autumnal equinox is on or around the 21st September. Summer officially commences on the day with the greatest amount of daylight, the 21st June or summer solstice.

The winter solstice occurs on the shortest day, the 21st December. ‘Solstice’ is a combination of two words meaning ‘sun standing still’ and the days are so called because they are the days when the apparent movement of the Sun reaches its limits and reverses course again.

Apocalyptic Dates In The Future

Wednesday, May 19th, 2010

Predicting the demise of the world has almost certainly been going on since man began thinking, whenever that was. It is warned about in Revelations in the Bible, so that must be about 2,000 years ago.

Nonetheless, it is the predictions of Nostradamus that are the most well-known and most abundant. Some biographical records of Nostradamus’ life state that he was afraid of being victimized for heresy by the Inquisition, although neither prophecy nor astrology fell under their jurisdiction. He would have been in danger only if he had practiced magic to back up his predictions.

In fact, his contact with the Church as a seer and a physician were always very good. His short imprisonment at Marignane in late 1561 came about merely because he had published his 1562 Almanac without the prior consent of a bishop, contravening a recent royal decree.

Here then are a couple of the prophesies of the ending of the world and the annihilation of mankind.

December 21st, 22nd or 23rd 2012 are all possible dates for the ending of the world according to the ancient Mayan Calendar.

2012 has been determined by some to be the first potential date for the passing by of Planet X (Wormwood) and the demise of the world, as mentioned in Revelations, although this is fervently debated by Biblical experts and astronomers alike.

2012 is also the year given by Nostradamus as the possible demise. He gave three possible years for the apocalypse: 1994 and 1998 so this is his last opportunity to be correct.

2010 is the year so says the Hermetic Order of Golden Dawn.

In 1143 St Malachy prophesied that there would be only another 112 more Popes. The current Pope Benedict is the 111th. He also predicted that the final Pope would be known as Peter of Rome, so we will have to wait and see for this one.

2017 is the year specified to the Sword of God Brotherhood by the Angel Gabriel.

November 13th 2026 is the date according to a 1960 copy of ‘Science’ magazine. The writer said that this would be the day that the planet’s human population would ‘reach infinity’.

2033 is held by many to be the 2000th anniversary of the crucifixion of Christ and a potential date for his return, which would indicate the demise of our Earthly period.

4,500,000,000 AD is the approximate date at which the Sun is due to explode and in so doing, destroy the inner solar system including our World. Nobody knows, but unless we wipe out ourselves first, this latter date is probably the most accurate and scientific date for the destruction of the planet.

Christian Holy Days

Saturday, April 3rd, 2010

Christmas – is the celebration of Jesus’ birthday. Although the exact date of his birth is unknown, December 25th was probably chosen because it coincided with a pagan mid-winter festival. The ‘Twelve Days Of Christmas” mark the days between Christmas and Epiphany (January 6th), which was the day of the wise men’s visit.

Easter – is the most important day in the Christian calendar, because it celebrates Christ’s Resurrection, which gave / gives Christians the hope of salvation and eternal life. Easter always falls on the first Sunday after the first full moon after the vernal (Spring) equinox, which is on 21st March.

Shrove Tuesday – (Mardi Gras or Fat Tuesday) was originally a day of penance, but is now marked by merrymaking. It is the day before the beginning of Lent.

Ash Wednesday – is derived from the marking of a cross on the forehead of believers with the ashes from the burnt palms used on Palm Sunday.

Lent – 40 days of atonement and fasting

Palm Sunday – the Sunday before Easter, celebrates the arrival of Jesus at Jerusalem, where palms were laid on the road before him.

Maundy (Holy) Thursday – the day of the Last supper.

Good Friday – is the day of Christ’s crucifixion.

Holy Saturday – is the day before the Resurrection.

The Annunciation – March 25th is celebrated by Catholics as the day that Archangel Gabriel told Mary about her impending pregnancy.

Trinity Sunday – is celebrated by some denominations in honour of The Father, The Son and The Holy Spirit. It was declared part of the holy calendar in 1334 by Pope John XII.

Corpus Christi – Catholics remembers the presence of the body of Christ on the Thursday after Trinity Sunday.

All Saints Day – this mainly Catholic celebration is on November 1 and honours all Christian saints.

Advent – a religious season that begins on the Sunday nearest to November 30 and lasts until Christmas Day. It celebrates the birth of Jesus and anticipates his Second Coming. It was once a period of fasting, but now no longer.

Holy Days Of Obligation – are feast days in the Catholic calendar marked by attendance at mass and the avoidance of unnecessary work. There are six in the USA: Solemnity of Mary – January 1: Christ’s circumcision, ie his first shedding of blood Ascension – 40 days after Easter Assumption – August 15: Mary is accepted into Heaven All Saints’ Day – November 1 Mary’s Immaculate Conception – December 8 Christmas Day – December 25.

Millennium Prophesies

Wednesday, March 31st, 2010

A lot of people predicted that the start of the new Millennium, the year 2000 would be the date of the apocalypse. However, fortunately, they were very wide of the mark.

What is it that makes people to attempt to predict disasters? Is it because they are attempting to warn people or because they wish to scare people? Frighten people, I think and thereby gain advantage over the naive.

These apocalyptic predictions go back thousands of years and even appear in the Bible. Their only raison d’etre is to frighten people and so gain money, power and influence over them.

Even the millennium bug turned out not to be a problem with computers functioning perfectly well after midnight in spite of claims by ‘computer experts’ that there would be a worldwide crash of stupendous importance. The computer industry made a fortune out of frightening businesses and individuals with their deceit. That was the scam of the Nineties to end all swindles!

So why all the hype? Was it just the arrival of a new millennium, which gave rise to so many to make predictions on this date rather than stick to their usual common sense? Yes, I think. People saw the chance of a lifetime to rip others off and they jumped at it.

Needless to say there were hundreds of predictions made ranging from the arrival of aliens and the Second Coming of Christ to airplane crashes. None of which came true. Here are a few of those less than precise predictions:

May 5th was the day upon which all the planets lined up. The prediction was that the gravitational force of all these heavenly bodies in alignment would cause massive earthquakes, huge tides and volcanic eruptions.

A lot of people also prophesied that the shifting of the poles would occur during 2000 and that this would cause disastrous events such as high tides, widespread electrical failure and computer failures, which would mean economic disaster for the larger countries and insurance firms.

I do not know what you think, but perhaps instead of worrying about the end of the world (most doom-mongers have settled on the year 2012 for the destruction of the world) we should work together to make the best of the time we have left on this planet, as well as ensuring that we pass the planet on to the next generation in the same condition as we received it.

If we act in this way, we may hold off the apocalypse for a long while yet. We are far more likely to suffer apocalypse through nuclear war, global warming and events which are preventable and within our control, than cosmic events which we have little control over such as asteroids or the Sun’s turning into a red dwarf and eventually exploding.

Astronomy – Important Pre-Christian Dates

Wednesday, March 10th, 2010

There is no doubt that astronomy is the oldest science and there is also no doubt that astronomy was being studied by everyone, not only the wise men, thousands and thousands of years ago.

We do not know precisely why they did it, but we can surmise that early man noticed a correlation between the weather and the stars, which were themselves not fully understood, of course.

Early man, probably even as far back as Neanderthal man, noticed the relationship between the weather and herd movements and crop growth, or at least fruit and nuts on local trees, if they did not have planted crops.

This means that people could see a connection between the stars and food availability. This relationship was probably ritualized into some sort of religion like early Wicca. Therefore, the stars became a very important part of the lives of every single person and it is likely that astrology and astronomy were widely intermixed by the average person.

However, there were also people who did not only use the stars as some vast celestial clock and who tried to make sense of the whole shebang. I am going to narrate below, eight of the most important dates or years in the history of astronomy before Christ walked on the Earth. In no way forget that they had nothing but an abacus to do there calculations and no telescopes, which came about two thousand years later.

585 BC: Thales of Miletus (c. 625- c. 547), a Greek, predicted a solar eclipse in Asia Minor purely on the basis of his observations and calculations. It was not a lucky guess!

c. 400 BC: the astronomer Oenopedes (5th. century). also a Greek, announces that the Earth is tilted on its axis with respect to the Sun.

352 BC: the Chinese report what they called a ‘guest star’, a supernova, which was the earliest reported sighting.

340 BC: The astronomer, Kidinnu (b. Babylon c. 379 BC) discovers the precession of the Equinoxes, ie the apparent change in the position of the stars caused by the Earth’s wobbling on its axis.

c. 300 BC: a ‘committee’ of Chinese astronomers compile star maps of the visible universe.

c. 240 BC: Chinese astronomers observe and make notes about Halley’s Comet. Also Eratosthenes of Cyrene (c. 276 – c.194 BC), a Greek, correctly calculate the Earth’s dimensions.

165 BC: Chinese astronomers notice sunspots for the first time.

c. 130 BC: the astronomer Hipparchus of Nicea (b. 147 BC), a Greek, correctly calculates the distance to the Earth’s Moon and also rediscovers the precession of the Equinoxes.

You will notice from the dates above that obviously not everyone let nature and the stars rule their lives, as the comon farmer or hunter did. Some men actually put pen to paper, but before pen and paper even existed, and tried to work out ‘why these manifestations occurred?’.

These people must have been remarkable men to have worked these measurements out by calculation, observation by the naked eye and rationalization alone.

The Chinese Calendar

Wednesday, March 10th, 2010

Before their implementation of the Western solar calendar system, the Chinese almost exclusively followed their own lunar calendar for working out the times of planting and harvesting and festival holidays. Though people in China today use the Western calendar for almost all business, governmental and practical matters of daily life, the old arrangement still serves as the basis for working out numerous seasonal holidays. This coexistence of two calendar schemes has long been acknowledged by the people of China.

However, this does not only happen in China, it also occurs in most other Eastern countries, like Thailand, and most Arabic countries.

A lunar month is determined by measuring the period of time needed for the moon to complete its full cycle of 29 and a half days, a standard that makes the lunar year a full eleven days shorter than its solar counterpart. This difference is corrected every 19 years by the addition of seven lunar months.

The 12 lunar months are further divided into 24 solar divisions characterized by the four seasons and times of heat and cold, all of which bear a close relationship to the yearly cycle of agricultural work.

The Chinese calendar – very much like the Hebrew calendar- is a combination of the solar and lunar calendars in that it strives to have its years concur with the tropical year and its months coincide with the synodic months. It is not surprising that a few similarities exist between the Chinese and the Hebrew calendar.

For example, an average year has 12 months, a leap year has 13 months. An ordinary year has 353, 354, or 355 days, a leap year has 383, 384, or 385 days. When determining what a Chinese year will be like, one needs to make a number of astronomical calculations.

First of all, you have to work out the dates for the new moons. In these cases, a new Moon is the completely black Moon (that is to say, when the Moon is in conjunction with the Sun), not the first visible crescent, as is used in the Islamic and Hebrew calendars. The date of a new moon is then the first day of a new month.

The reason why the majority of countries which had their own calendars had to dump them in favour of the Western, Julian calendar that we use today, is business. First the British and then the Americans ran international business and they used the Julian calendar.Anyone who wanted to work with them had to follow suit. This is why national policy often varies from local custom in Third World countries.

The government desires to deal on the International markets, but the ordinary family in the country can not. So, the government took up the Julian calendar but the people only pay lip service to it. I live in Thailand and people here do not even use the 24 hour day divided into two halves. Their day has four sections of six hours each and the first part starts at 6AM, not midnight. Therefore, they have four 4 o’clocks a day, for instance and no 7 o’clocks. They are also 543 years ahead of us, although this is more common, for example in Muslim countries.

The Ancient Chinese Lunar Calendar

Monday, March 1st, 2010

Prior to their adoption of the Western solar calendar scheme, the Chinese almost wholly followed their own lunar calendar for determining the times of planting and harvesting and festival days.

What Is A Promotional Strategy?

Saturday, February 13th, 2010

Even if you were to invent something earth-shattering, you would not earn any money from of it if you left the invention on your desk. The only way you can profit from it is by selling it and in order to achieve this, you have to inform people that it exists, that it is for sale and where they may get it from. In other words, you have to advertise it.

The US Patents Office has issued thousands patents for items that never made it and many of those did not make it, not because they were not good concepts, but because their inventors did not know what to do with them. A business is more or less the same as a new invention. It has to be advertised, unless it is situated in the middle of the only street in town.

Having already launched the business, it is to be expected that, you have already worked out your intended market and evaluated the need for your goods or services. Now you have to convert those potential customers into satisfied customers and this is where your promotional strategy comes in.

A promotional strategy is nothing more than a for reaching your target market, which is of course the people most likely to need your services or products. At its simplest, your promotional strategy might consist of just hanging a sign over your door and relying on word of mouth from satisfied customers to spread, thereby doing your advertising for you.

In some cases, this is indeed all the advertising a business needs, but the circumstances are not that common really. It works, if you are operating in a very small town or if your product or service is unique or very specialized or if you enjoy a long-standing good reputation. However, normally, customers require more details to go on before they will be drawn to your business.

Therefore, the objective of your promotional strategy should be to get in touch with the greatest quantity of potential customers by the most economical use of your means, which may include money, personnel and facilities. This means that you have to divine the channels of communication most used by your potential customers and try to reach them through those. This is usually constrained by a budget.

Advertising involves the purchasing of time or space in the media you have selected in order to market your business to your intended market. You then have to come to a decision which form of advertising you are going to use: institutional or product advertising. Institutional advertising promotes the firm’s name as in: ‘Larry’s Boot Shop – The Best In Town’, whereas product advertising is more specific and might read: ‘Nike Walking Boots – 30% off at Larry’s. Offer Finishes Friday!’

Both forms of advertising can be successful and lend themselves better to some media than to others. Institutional advertising is better carried out on shop signs, sign-written vans or windows or promotional calendars, that is, static, long-term, business name advertising and product advertising is better done by newspaper, magazine, radio and TV, where one-off special offers can be promoted.

US Minor Holidays And Occasions

Wednesday, February 10th, 2010

Below is a directory of minor holidays and occasions in the United States. Some of them are practically unknown, and others are quite obscure.

April Fools’ Day – (April 1): the day for practical jokes (only before noon in the UK). Its origins are obscure, but it bears a similarity to an ancient Roman festival for the goddess of nature.

Arbor Day – (last Friday in April): devoted to trees and their conservation. It is held on December 22 everywhere else in the world.

Armed Forces Day – (third Sunday in May): a day to honour the US armed forces.

Citizenship Day – (September 17): replaced Constitution Day in 1952 by presidential proclamation.

Daylight-Saving Time: was first proposed by Benjamin Franklin in 1784, but became the Uniform Time Act in 1966. It is not observed in Hawaii, the Eastern Time Zone of Indiana, most of Arizona (except on the Navajo Reservation), American Samoa, Puerto Rico, the Virgin Islands and Guam.

Election Day – (Tuesday after the first Monday in November): presidential elections are held in years divisible by four and elections for all members of the House of Representatives and one-third of the Senate in years evenly divisible by two.

Fathers’ Day – (third Sunday in June): was first observed in West Virginia in 1908, but this uniquely American holiday was not made official until 1972.

Flag Day – (June 14): was first celebrated in 1877, which was the centenary of the adoption of the modern design. Truman passed the Flag Day Bill in 1949.

Groundhog Day – (February 2): on this day the groundhog peeps out of his burrow. If he sees his own shadow there will be six weeks of Winter to follow, otherwise Spring is just around the corner.

Halloween – (October 31): All Hallow’s Eve is the day before the feast of All Saints. It started as a pagan custom honouring the dead and a celebration of Autumn. ‘Trick or Treat’ is purely American with no historical foundation.

Kwanzaa – is a secular observance by African-Americans to commemorate their African heritage. It begins on Dec.26th when a candle in a candelabrum is lit every day for seven days. It was first practiced by Maulana Karenga in 1966.

Mothers’ Day – (second Sunday in May): was thought of by Anne M. Jarvis of Philadelphia as a way for children to pay homage to their mothers. It received presidential proclamation in 1914.

National Maritime Day – (May 22): was proclaimed in 1935 to memorialize the SS Savannah’s first successful transatlantic crossing by a steamship in 1819. It is also a day of remembrance of merchant mariners who died in defense of their country.

National Teachers’ Day – (Tuesday of the first full week in May): is when pupils are meant to honour the teaching profession.

St. Patrick’s Day – (March 17): has been borrowed from Ireland where it is their national saint’s day.

St. Valentine’s Day – (February 14): was initially to honour two saints martyred by Emperor Claudius (214 – 270), but has been devoted to lovers since the Middle Ages.

Susan B. Anthony Day – (February 15): Anthony (1820 – 1906) worked for women’s rights and suffrage.

United Nations’ Day – (October 24): commemorates the endorsement of the UN Charter in 1945 by the then five permanent members of the Security Council.
