What is the difference between New Year s Day in ancient times and New Year s Day today?

In the calendar, it is customary to say that the earth revolves around the sun for one year. However, since the earth orbits around the sun without a fixed beginning and end, the beginning and end of the year are artificially prescribed, which causes inconsistencies in various calendars. According to legend, the word "New Year's Day" comes from one of the earliest emperors in our country - 颛顼, who stipulated that the first month of the lunar calendar is "Yuan", and the first day of the lunar month is "Dan".

Later, some dynasties changed the date of New Year's Day, but in principle, the first day of each year was still New Year's Day, such as the Xia Dynasty took the first day of the first month as New Year's Day, but the Shang Dynasty took the first day of December as New Year's Day, and the Zhou Dynasty took the first day of November as New Year's Day, and the Qin Dynasty took the first day of October as New Year's Day. Until the time of Emperor Wu of the Western Han Dynasty, the great historian Sima Qian and others reformulated the calendar, and stipulated that the first day of the first month of each year is New Year's Day, and it has not changed since then.

After the success of the Xinhai Revolution in 1911, it was decided to adopt the internationally accepted Gregorian calendar, so the lunar New Year's Day was changed to "Spring Festival", and January 1 of the Gregorian calendar was called New Year's Day. When the People's Republic of China was founded, it began to officially use the "A.D. chronology method", and set January 1 of the Gregorian calendar as New Year's Day every year.

Nowadays, most countries in the world regard January 1 as New Year's Day every year, because they mostly use the internationally accepted Gregorian calendar. However, there are also some countries and nations that have different dates on New Year's Day due to their local calendar traditions, religious beliefs, customs, seasons and climates, which also makes the world colorful and more national.

New Year's Day is a traditional New Year for people all over the world. New Year's Day is the first day of the year. New Year's Day is a compound word, apart, Yuan is the meaning of the first or beginning, and the original meaning of the word Dan is a round of red sun rising from the ground.

In China, the name New Year's Day comes from the legendary Three Emperors and Five Emperors, who took the first month of the lunar calendar as the first month and the first day of the new year as the day. According to the "Historical Records": the Xia Dynasty took the first day of the first month as New Year's Day; In the Zhou Dynasty, the first day of November was the New Year's Day; Qin takes the first day of October as New Year's Day.

After the Xinhai Revolution, China called the first day of the first lunar month the Spring Festival, and January 1 of the Gregorian calendar called the New Year, not New Year's Day. It was not until September 27, 1949, that the first plenary session of the Chinese People's Political Consultative Conference officially designated January 1 of the Gregorian calendar as New Year's Day by using the A.D. chronology method, and the first month of the lunar calendar must be the Spring Festival.

The Egyptian calendar, the ancestor of the lunar calendar, celebrated the day Sirius and the sun rose together as New Year's Day; Afghanistan celebrates the vernal equinox as New Year's Day; Jews observe the autumnal equinox as New Year's Day; And the New Year's Day of the Eskimos in the cold zone is not fixed, and they regard the first rain as New Year's Day. In 46 BC, the Roman Emperor Julius Caesar established the Julian calendar, which began with the winter solstice as New Year's Day. However, people insisted on New Year's Day as New Year's Day, so New Year's Day was postponed to 10 days after the winter solstice.

The ancients used the lunar calendar for New Year's Day, and the first day of the first month of the lunar calendar is actually the current Spring Festival;

And now New Year's Day is according to the solar calendar, that is, January 1 of each year (if you count according to the lunar calendar, it is estimated that it is only November or December).

New Year's Day began with Sun Yat-sen's election as the provisional congress. In ancient times, there was no New Year's Day, and the Qin Dynasty took October as the first month of the year.

January 1 is the beginning of the new year in 2023, and Chinese are accustomed to calling this day "New Year's Day". The term "New Year's Day" is a "native product" in ancient China, not a "foreign product", which has been used in the lunar calendar (summer calendar) for more than 4,000 years, but the current "Yuan Model Sales Dan" was established in 1949.

The "summer calendar" produced during the Xia Dynasty in China is the current "lunar calendar", which stipulates that the first day of the first month of the lunar calendar is "New Year's Day".

"New Year's Day" is a compound word in Chinese Chinese, and "yuan" is "beginning" and "beginning"; "Dan" is a pictograph, recorded in bronzes from the Yin and Shang periods, which indicates that the sun rises above the earth's level. "New Year's Day" is the "first day", that is, the first day of the year.

In history, "New Year's Day" has many titles, such as "Yuan Shuo", "Zhengdan", "Yuan Zheng", "New Year", "First Year", "Tai Sui Day", "New Year", "New Year", "New Year", "New Year", "Rooster Day", etc., but among the many titles, it is still called "New Year's Day" is the most common and the longest time.

Due to different dynasties, the calendar adopted is also different, and the time of "New Year's Day" in Chinese dynasties is not consistent, such as the Xia Dynasty on the first day of the first month, the Shang Dynasty on the first day of December, the Zhou Dynasty on the first day of November, and Qin Shi Huang unified the six countries, and then changed to the first day of October. In the period of Emperor Wu of the Han Dynasty, the summer calendar was reused, and the first day of the first lunar month was regarded as the "New Year's Day". After that, except for a few dynasties, all other dynasties used the summer calendar until the end of the Qing Dynasty.

In 1911, the Xinhai Revolution overthrew the Qing Dynasty and decided to adopt the Gregorian calendar, calling January 1 of the Gregorian calendar "New Year's Day" and the first day of the first lunar month "Spring Festival", although it was not officially announced and named at that time.

The "New Year's Day" mentioned today is on September 27, 1949, on the eve of the founding of New China, when the first plenary session of the Chinese People's Political Consultative Conference passed a resolution that after the founding of New China, China changed to the common era of the Common Era. Since then, January 1 of the Gregorian calendar has been officially called "New Year's Day", and the first day of the first lunar month is "Spring Festival".
