Dating methods back then were done manually. They didn’t provide specific information about the year and month, as we refer to it as 2010 nowadays. And whether it is official or private, they are used for recording.
In fact, if we look at it from the calendar, a strange thing happened in October 1582; it disappeared for 10 days starting from October 4 and jumped directly to the 15th. This phenomenon also caused a lot of people to speculate. (Friends, you can use your phone to check your calendar!)

Some people on the Internet believe in magical theories that suggest the Earth has experienced major transformations, and time stopped when alien civilizations visited our planet.
Some believe advanced civilizations hide from humans by pretending to be gods or monsters. However, this is not as extreme as it sounds.

In fact, it was because of the instructions of the European Pope that many people discovered that the time began to appear wrong in 1582. They hired several astronomers to study to avoid mistakes and eventually found that a year has 365.24 days. Although there are still some errors, it is much better. Then, the Pope also directly ordered the deletion of these ten days. Although it sounded very lax, it was deleted in the end. So after the end of October 4, 1582, it jumped directly to October 15. There was speculation about the time when humans disappeared. The 10 years were proven wrong and removed. Oh my god, the subsequent theories about cows, ghosts and snake gods no longer exist.

When this policy was first implemented, it was unacceptable to many countries, especially the United Kingdom. They chose to keep their own laws but later realized that the inconvenience caused by the difference in time concepts was too significant. Much more.
China was in the Ming Dynasty during that period. People had their own way of recording time and chronology. So, it didn’t affect the Chinese people. What do you think about this? Welcome to leave a comment below.
