Where is the International date lineWhich is the International Date Line?
I' m following a dream/bucket list target to be on the international dateline. International Definition des Datums im Oxford Advanced Learner's Dictionary.
International Date Line - Geography for Children
Supreme Mercury is the degree of meridians running through Greenwich, England. There is an fictive line on the opposite side of the earth at 180°, known as the International Date Line. When you have taken a boat trip around the whole globe, you would see a first-hand phenomenon that would help you comprehend the importance of an international date line.
Magellan went with 241 men touring the world. On their travels, these men kept very accurate notes. After all, how could these men lose an awful whole days? They gradually got bogged down as they travelled around the world. And if you are staying in one place, a full 24 hour workday.
But if you are travelling in the opposite sense of the Earth's orbit, your days will be slightly longer than 24 hrs as you are ahead of the set point. When you are travelling with the Earth rotating, your days are slightly less than 24h because you are travelling into the sundown.
There are indeed two Earth working at the same hour at any one point in the world. Another date begins at 12 o'clock on the International Date Line. It' s traveling around the world until it ends 48-hour later at the international date line. The date would be changed either forwards or backwards if you were travelling across the International Date Line.
That line is actually in the center of a timezone. That means that the hours on the watch would not vary when you cross the watch, only the date.
What was the International Date Line like?
Even though the contemporary globalised and interconnected worlds and today's telecommunication depends on extremely high timing and positional precision, this has not always been the case. Indeed, this fixation with precision in terms of timing and placement is relatively new and has only been around for a few hundred years.
Previously, it was just not possible to co-ordinate when and where everyone was at a given point in it. Greenwich meridian was founded in the early eighteenth centuary, but this was mainly for navigating in shipping. It is a little more enigmatic, and since it is in such an unpopulated area, most human beings do not really know what it is.
It' just an indiscriminate line in the sea? It' selected for comfort, and because it divides the worid in half. In front of the watches and the immediate communications the timing was quite an easy procedure. Obviously, this system was somewhat flawed because towns of the same length, in certain areas, could have their "lunch" at a different point in it.
With the modernization of the watch industry, watches became more and more sophisticated and the demands on the precision of timing rose (train timetables, phone conversations, etc.). In order to resolve this overall issue, the idea of timezones until 1900 was designed and formalised, dividing the globe into 24 different timezones, one for each lesson of the today.
It was in line with the system of linear and latitudinal positions on the Earth. The degree of parallelism was set on the perpendicular axes with the equator set to 0 degree and the pole to +/-90º. But the meridian was a little more challenging, since the choice of the location where "0 degree longitude" should be was an important point of Pride.
England, however, had the biggest Marine in the whole wide area of the planet and the most settlements in the whole wide area. So they were in the best place to determine the point on the cart. That is why the Greenwich meridian was created, which is 0° long and runs right through the centre of London.
That helps to unify times and locations, as most timezones were 15 longitudes long. By now the worid already had an idea of how dates and times worked (i.e. date and date were changing at midnight), on the basis of the Greenwich timezones. But it was also necessary to delimit the "change of date" somewhere else in the atlantic.
As there is a " moving date line " from a technical point of view, as middlenight took place in every other timezone, there had to be a fixed place where a new date started from a technical point of view. An international date line was therefore necessary. The westbound crossings over the IDL have now added 24 hrs, the eastbound crossings subtracted 24 hrs.
This is because we needed an international date line because a scrolling date line would never allow the date to be changed! This might seem insane, but if you just circle the planet with the timezones to advance the date, "mathematics" doesn't work. In essence, if you travel around the Earth's Earth to the Orient (the Earth's direction) and use only the Earth's internal timezones, you would end up winning a single date for someone who has been there.
There are two distinct dates on the international date line, which basically tells the rest of the globe that the date at the IDL and then at any other location changes at noon. The date in the East is the date one full year ahead of the line, to the right of the line.
Considering the oddity of the data on the opposite sides of the line, the choice of a place for them on earth had to be done very diligently. But it was just a fluke that the best place was on the opposite side of the Greenwich meridian as well.
IDL is 180 degree long, Greenwich is 0 degree long and there are 360 degree latitude on the world. IDL was selected because it passes right through the Pacific Ocean, in a relatively flat line, although it is zigzagging around East Russia and the Aleut Islands of Alaska.
If two sides of the same town had different data, it would be quite a mess, so the line was curved and tampered with to prevent this kind of problem. It was prudent to cut through the Pacific Ocean, as few humans will ever be able to jump from one date to the next, avoiding greater muddle.
Most of the ICL is recognized worldwide because it gives a certain order to our timing and schedule co-ordination. However, the ITL is not part of international jurisprudence, so it is up to the Länder to comply with the data they have chosen. We may not be able to fulfill H.G. Wells' dream for all our future timetravelers out there, but when you cruise out into the Pacific Ocean in the afternoons of July 14 and across the ITL, you will all of a sudden be back in the aftersho?
If you have a sailing boat and some killing timeframe, who needs a timeframe?
