Ten days deleted in history

  If someone tells you that the ten days from October 5 to 14, 1582 do not exist in history, and that nothing happened in these ten days, you will definitely feel that this is nonsense. In fact, this incident is indeed true.
  This matter should start with an astronomer and a politician. The astronomer is a Greek named Sosichenni, who is not well known. However, that politician is a famous figure, he is the Emperor Caesar of ancient Rome.
  As we all know, the universal chronology is the AD era. Its predecessor was the “Julian Calendar” practiced in the Roman period. Julian was Caesar the Great. For a long time, Rome was the center of Western civilization, but it did not have a unified calendar. The French scholar Voltaire once sarcastically said: “The Romans won many battles, but they don’t know when they fought.” Caesar After becoming emperor, he determined to change this situation.
  In 46 BC, Caesar asked Sosichenni to go to Rome to help him modify the calendar. In the end, Caesar adopted Sosichenni’s suggestion, based on the Egyptian solar calendar, and Xunxin compiled a calendar, the Julian calendar. On January 1, 45 BC, Caesar ordered the implementation of this calendar in Rome, which improved the previous chaos. However, this calendar also has problems.
  The Julian Calendar uses the return year as the basic unit. The calculated year of the same return year was 365.25 days, which is 0.0078 days longer than the actual return year of 365.2422 days. At first, this was not a problem, but as errors accumulate, the trouble becomes bigger and bigger. For example, the “Julian Calendar” originally set the vernal equinox to be around March 21st, but after hundreds of years, the date of the vernal equinox on the calendar is getting earlier and earlier, which brings a lot of trouble to real life, because farmers Farming according to solar terms. In addition, this has had a great impact on the religious world. Because the church must determine Easter based on the vernal equinox, over time, on which day Jesus was “resurrected” has become a big question. It seems to the congregation that this is not serious.
  By 1582 AD, with the advancement of astronomical observation technology, people discovered that the vernal equinox had actually advanced to March 11, ten days earlier than the originally scheduled March 21! How to do this? At that time, the most important person in Europe was the Pope. The Pope Gregory XIII felt that this situation could no longer continue, so he set out to solve the problem. Gregory XIII ordered a committee of astronomers and high-ranking monks, with the mathematician Kravis as its chairman.
  In the end, the committee proposed a plan of 365.2425 days in a year, which was much closer to the reality of the same year. However, there are still errors in this plan, but the difference between the two is very small, the error is less than one day every 3323 years, and it has no impact on the lives of ordinary people. Soon, the Pope promulgated this calendar, which was called the “Gregorian Calendar”, which was later commonly known as the “Gregorian Calendar.”
  Although the problem of the same return year error is almost solved, what about the ten days difference? Kravis and the others did not think of a way for a long time, so they simply suggested to the Pope to simply erase ten days from the calendar! Specifically, it is to let the people pass October 15th directly after October 4, 1582. After receiving this suggestion, the Pope was also very surprised, but felt that there was no other way. He had no choice but to release the Pope’s decree and erase October 5-14, 1582! After this order was issued, despite the complaints from the people, everyone could only follow it. So the error is finally gone.
  In this way, the pope swiped his pen and disappeared in ten days. However, Britain initially did not buy the Pope’s account, and resolutely opposed it. This caused the British calendar to be different from the calendars of the European continent. The British persisted in this way for 170 years. At the end of the day, the British really couldn’t bear it. Passing legislation also wiped out the extra days.
