Answering this question is not so common as easy as it sounds. In connection with this problem almost 450 years ago was a mistake that caused great concern to many people. Almost three years sailed the oceans of the first expedition around the world led by Magellan. Magellan himself died during the trip and five ships that set off, only the ship "Victoria" returned to Seville on September 6, 1522. The ship was almost destroyed and he, of 265 men who had left, returned only 18, weak, sick and thin as skeletons. Directly from the boat carrying lighted candles in their hands, trembling with weakness, he went to the cathedral of Seville to ask God for forgiveness of sins without knowing it and without wanting to, they had made during the long voyage. yCuales were these sins? On the way back when a group of marine Victoriaa a landed on the islands of Cape Verde to buy supplies and water they saw on the islands, that day was Thursday, however, in the "Victoria" in accordance with the Logbook was Wednesday. When the a Victoriaa came to Seville was no doubt that in the Official On-Board had erred in one day.
They had left a day without counting. The big sin that caused so much concern was that the sailors had all the religious festivals celebrated a day earlier than due. Therefore, in the cathedral of all knee asking God's forgiveness for their sins. The most interesting case was that the Marines were not wrong. In the Diary of Onboard were marked every day. And where was the secret of the mistake? The Earth spins on its axis from west to east, and every 24 hours makes a full turn. Magellan's expedition was in the opposite direction, from east to west.
During the three years that was the trip, the sailors gave a complete revolution around the Earth but in the opposite direction which moves Earth. Thus during the three years they walked around than our planet, and that was the day that they lacked. If the expedition had made the trip in the same direction as the Earth spins from West to East, the opposite had happened, they'd been around more than Earth. When the distances are small, the time difference is small, but large distances is not the same. If at 12 pm on December 31 sent a message by e-mail from Moscow to Managua, the message will be received in Managua where they will be at 3 pm on December 31. That is, the message will receive nine hours before being sent.
