Why is Magellan s global voyage missing a day?

This is due to the International Date Line.

The International Date Line (180 degrees meridian) is the 12th East Zone to the west and the 12th West Zone to the east, so crossing the International Date Line from west to east will result in a day of subtraction, while crossing the International Date Line from east to west will result in an additional day.

To say a few more words, the time zone corresponding to the 0 degree meridian is the middle time zone, the degree of the meridian line east of the 0 degree meridian is the east longitude, and the time zone also corresponds to the east 1 to the east 12 districts, in the same way, the 0 degree of the meridian west of the meridian is the west longitude, and the time zone also corresponds to the west 1 to the west 12 districts.

So imagine that when you go east from the Central Time Zone, you will go from the 1st East District to the 12th East District, and then you will enter the 12th West District, and the date will be reduced by one day.

The date line is immovable, and in the Beijing Olympics at 8 p.m. on 8 August 2008, this moment can bring people all over the world to the same day.

There are two date lines, and the date line, which is basically at 180 degrees longitude, is called the "international date line". The other is called the "natural day line". It is actually the meridian at zero local time, which, together with the international date line (180 degrees of longitude), divides the earth into two different dates.

And when the natural date line coincides with the international date line, all parts of the earth are on the same date.

Because his fleet circled the earth. The longitude of the earth is different, the time is also different, and the circumnavigation is exactly 24 hours apart, which will inevitably lead to inconsistencies between the recorded time and the external time. It's just that at that time people didn't recognize the problem (because it was the first circumnavigation of the world).

Since the Earth rotates from west to east and the fleet sails from east to west, there will be one less day. As for the International Date Line, it was an imaginary line that was determined later.

Magellan sailed from east to west, so he was constantly chasing the effect of the Earth's rotation and should have added one day to his crossing of the International Date Line, which he crossed from east to west. That is, from the West 12th District to the East 12th District.

Geography homework also asks questions, don't connect

Magellan's circumnavigation of the world was a major achievement in the history of world navigation. Magellan's successful circumnavigation of the globe not only opened new routes, but also proved that the earth is round and that the earth is a round sphere through the expeditions carried out by his expeditionary fleet.

The expedition led by the Portuguese seafaring explorer Magellan set out on September 20, 1519 and successfully returned on September 6, 1522, which lasted 1,082 days, completing the first circumnavigation of the world. The Magellan route is 60,440 kilometers long.

Magellan was born in 1480 in northern Portugal to a family of broken knights. Around the age of 10, he entered the royal palace and served as the queen's attendant. At the age of 16, he joined the Portuguese National Maritime Affairs Department, where he became familiar with the various aspects of maritime affairs.

Fernando Magellan, one of the world's navigators. Portuguese, born in 1480 into an aristocratic family. On September 20, 1519, Magellan, with the patronage of the King of Spain, led an expedition of 266 men in five sailing ships from the Spanish port of Sesanju Villa, and began his famous voyage around the world.

Magellan led a detailed voyage across the Atlantic Ocean to Tierra del Fuego in South America, and after many hardships, through the Strait of Magellan into the Pacific Ocean. The fleet was already in a difficult situation of lack of food, and the sailors were starving, feeding themselves with the belts caught up with the mast, but the fleet never stopped. While passing through the Philippine Islands, the expedition clashed with the island's natives, and Magellan was wounded and killed, leaving only one ship left in the fleet.

The ship sailed to Spain via South Africa, and the plan to sail west from the west to the east was a real joke. He returned to the Spanish port of Seville on September 6, 1522, completing a three-year voyage around the world. Magellan's fleet's circumnavigation of the world proved in practice that the earth is a garden, whether from west to east or from east to west, there is no doubt that it can circle our planet and return to its original place.

Magellan's fleet sailed across the Atlantic Ocean in 70 days to reach the shores of the Americas, and then sailed south along the coast in search of a strait or southernmost headland across the American continent. After many hardships, including starvation, bitter cold, rebellion within the fleet, defections, and strayed into the estuary, they finally crossed a strait and reached the ocean off the west coast of America on November 28, 1520. This strait is named the Strait of Magellan, which is the strait that connects the two oceans at 52 degrees south latitude in the south of Chile in present-day South America.

Magellan's fleet was now limited to three ships. They sailed westward on the ocean for 110 days without encountering strong winds and waves, and they named the ocean the Pacific Ocean.

In March 1521, Magellan's fleet reached the Philippine Islands. As a result of his participation in the war of the island's clans, Magellan was seriously wounded and died. The remnants fled the Philippines in two boats, led by Eli Kano.

They crossed the Strait of Malacca into the Indian Ocean, and on the way, they were captured by the Portuguese navy. When he returned to Spain on September 7, 1522, only one ship (the Victoria) and 18 crew members remained.

The first circumnavigation of the globe completed by Magellan's fleet proved with conclusive evidence that the Earth is round. This will always be an indelible great achievement in the history of mankind.

Magellan's round-the-world voyage route is as follows:

Magellan's circumnavigation of the world was from 1519 to 1522, starting from Spain in Europe from the Atlantic Ocean to the south, bypassing the southern tip of South America and entering the Pacific Ocean, crossing the Pacific Ocean through Southeast Asian islands (mainly the Philippines, Magellan died) and then entering the Indian Ocean, then rounding the southern tip of Africa to reach the Atlantic, and then heading north along the west coast of Africa, and finally returning to Europe to complete the round-the-world voyage.

In this way, he carried muskets or something, tried to bring the local people to their knees, and then brought a colony to his own country. At that time, everyone basically did this, but the degree of resistance of the natives was also different. It was because of Magellan's wrong decision that the local revolt was inspired, and as a result of the revolt, Magellan's circumnavigation of the world would not have a good end - because Magellan was killed by the local residents.

Magellan's circumnavigation of the world significance:

Mak Pat Sun Ming-lun's circumnavigation of the globe through the oceans and back to Europe was a triumphant achievement in the history of world navigation, not only opening up new routes, but also proving that the earth is round through the expeditions carried out by his expeditionary fleet.

In addition, Magellan's voyage passed through all the sea, so he concluded that the earth was part of the ocean, and the land was only part of it. This statement has broken our traditional notions and caused us to think deeply. The various countries he visited during his voyage also deepened the ties between them, breaking the original pattern of isolation, and making the ties between countries on all continents closer.
