Thousands of years ago, ancient Greek astronomers calculated that the track of the Earth’s axis is constantly, even if in a very slow way, shifting in a uniform pattern. The change is very similar to the manner a spinning top slowly leans one way and then another as it slows down. It is a wobble that occurs 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 move in a circle. But very, very slowly. So slowly that it takes 26,000 years to go 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 lengthy, 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 position in relation to the stars behind it over the same period. It is for this reason that accurate star maps have to be stamped with the exact time and date to which they refer.

The calendar is such a routine, everyday item, 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 fixed pace about the imaginary line running between the North and South Poles named the Earth’s Axis. The time it takes to spin once is called a ‘rotation’ and this takes just under twenty-four hours. Nevertheless, because the Earth is constantly traveling around the Sun, the exact 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 move around the Sun in approximately perfectly circular routes called orbits. Each trip around the Sun is called a revolution and all the planets orbit around the Sun in the same direction. The course 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 location of the Sun in the morning and the see which stars appear 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 trip around the Sun, which seems like the Sun traveling 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 correct with the Earth’s motion.

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

From April to the 20th September, the Northern Hemisphere enjoys 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 begins 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 extremes and reverses direction again.

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

However, it is the predictions of Nostradamus that are the most well-known and most copious. Some biographical accounts of Nostradamus’ life assert 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 prophet and a healer were always very good. His short imprisonment at Marignane in late 1561 came about purely because he had published his 1562 Almanac without the prior permission of a bishop, contravening a recent royal decree.

Here then are a few of the prophesies of the end of the world and the destruction 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 possible date for the passing by of Planet X (Wormwood) and the demise of the world, as mentioned in Revelations, although this is hotly 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 expected to explode and in so doing, destroy the inner solar system including our Earth. Nobody knows, but unless we destroy ourselves first, this latter date is probably the most accurate and scientific date for the destruction of the planet.

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

What is it that compels people to try to forecast disasters? Is it because they are trying to warn people or because they want to frighten people? Frighten people, I think and thereby get 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 terrify people and so gain money, power and influence over them.

Even the millennium bug turned out not to be a problem with computers working perfectly well after midnight despite 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 lies. That was the scam of the Nineties to end all scams!

So why all the hype? Was it just the dawn of a new millennium, which caused so many to make prophesies on this date rather than stick to their normal common sense? Yes, I think. People saw the opportunity of a lifetime to rip others off and they jumped at it.

Needless to say there were thousands of prophesies made ranging from the arrival of aliens and the Second Coming of Christ to plane crashes. None of which came true. Here are a couple of those less than accurate prophesies:

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 predicted that the shifting of the poles would take place during 2000 and that this would cause catastrophic 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 demise of the world (most doom-mongers have decided 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 day of reckoning for a long while yet. We are far more likely to suffer apocalypse through nuclear war, global warming and events which are avoidable 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 ultimately exploding.

Christmas – is the celebration of Jesus’ birthday. Although the precise date of his birth is unknown, December 25th was most likely selected 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 initially a day of penance, but is now marked by merrymaking. It is the day before the commencement 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 penance and fasting

Palm Sunday – the Sunday before Easter, celebrates the entrance of Jesus into Jerusalem, where palms were strewn 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 remembrance is on November 1 and honours all Christian saints.

Advent – a religious season that starts 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.
