Why is there no 30 during the Spring Festival this year?

Wang Sichao, a researcher at the Purple Mountain Observatory of the Chinese Academy of Sciences, revealed that the months in China's lunar calendar are arranged according to the cycle of the moon's waxing and waning, which is called the "synodic month." The average length of a synodic month is 29 days, 12 hours, and 44 minutes (29 5306 days), which is not a whole number, and the number of days in a month is expressed as a whole number, so that it is sometimes a small month, 29 days; Sometimes it's a big moon, 30 days.

So how do you determine how many days there are in a month? Astronomers have always scheduled the first day of each lunar month on the day of the "new year". "Shuo" is the moment when the moon is between the sun and the earth, that is, the time when the lunar ecliptic longitude is the same as the solar ecliptic longitude (at this time, people on the earth cannot see the moon), so that the number of days between the two consecutive new longitudes is determined.

The first day of the first lunar month of the upcoming Year of the Rooster and the first day of the first month of the upcoming Year of the Dog coincide with the small moon, so there is no Chinese New Year's Eve.

Wang Sichao said that such changes in the lunar calendar allow the Chinese public to enter the Year of the Dog one day earlier and meet with the Golden Dog, the most loyal friend of mankind. The golden dog not only symbolizes the harmonious coexistence of humans and nature, but also is brave and energetic, symbolizing that the new year will be better.

According to astronomical experts, the last Spring Festival without Chinese New Year's Eve appeared in 2003, and the next time will be repeated in 2012.

Why is there no Chinese New Year's Eve this year?

The Spring Festival is approaching, and it is not difficult for people to find that this year, as soon as the 29th of the lunar month passes, it will go straight to the first day of the Lunar Year of the Dog, and there is no Chinese New Year's Eve. Why is this happening?

Wang Sichao, a researcher at the Purple Mountain Observatory of the Chinese Academy of Sciences, pointed out that the months in China's lunar calendar are arranged according to the cycle of the moon's waxing and waning, which is called the "synodic month". The average length of a synodic month is 29 days, 12 hours, and 44 minutes (days), which is not a whole number, and the number of days in a month is expressed as a whole number. Therefore, sometimes it is a small month, 29 days; Sometimes it's a big moon, 30 days.

The wax moon of the Year of the Rooster coincides with the small moon, so there is no Chinese New Year's Eve. The last Chinese New Year without Chinese New Year's Eve was in 2003, and the next time will be in 2012. (Reporter Cai Yugao, Zhou Runjian).

This year's Spring Festival is not the Chinese New Year's Eve.

Approaching the Spring Festival, Mr. Chen, a citizen, was surprised to find that this year's Spring Festival did not have the Chinese New Year's Eve when he looked through the New Year's calendar yesterday. The reporter opened this year's New Year's calendar and saw that the calendar had indeed passed the 29th of the lunar month, followed by the first day of the first lunar month, and there was no Chinese New Year's Eve. Why is there less Chinese New Year's Eve this year?

The reporter interviewed Wang Sichao, a researcher at the Purple Mountain Observatory in Nanjing.

Wang Sichao, a researcher at the Purple Mountain Observatory in Nanjing, said that the months in the lunar calendar are determined by the cycle of the moon's waxing and waning, and are called "synodic months." The average length of a synodic month is 29 days, 12 hours, and 44 minutes, i.e., days, not whole numbers, and the number of days in a month is expressed as whole numbers, so sometimes it is set as a small month or 29 days, and sometimes as a large month or 30 days.

It is understood that it is not common to have no Chinese New Year's Eve, the last Spring Festival without Chinese New Year's Eve appeared in 2003, and the next time will be in 2012. Reporter Li Xinyi intern Wang Rong.

Why is there no Chinese New Year's Eve this year?

Careful people will open the calendar and find that after the 29th of the lunar month this year, it will directly reach the first day of the first month of the Year of the Dog, and there is no Chinese New Year's Eve. Why does this calendar phenomenon occur? This is due to changes in the relative motion between the three celestial bodies, the Moon, the Earth, and the Sun.

According to Ma Weihong of the Purple Mountain Observatory in Nanjing, Chinese Academy of Sciences, the Spring Festival is the New Year in the traditional Chinese lunar calendar, and its arrangement takes into account both the sun and the moon. The Chinese lunar calendar calculates the number of days in a month based on the "synodic month cycle", and the day of "Shuo" is the first day of the new year, which is the time when people cannot see the moon at all; The day of "hope" is the fifteenth day, which is the time of the full moon. Since the relative motion between the Moon, the Earth, and the Sun is not static, the "synodic month cycle" is long and short, and there is a division of 30 days for the big month and 29 days for the small month in the lunar year.

At the same time, in order to ensure that the first day of the lunar month must be a new month, the arrangement of the large and small months is not fixed, which needs to be determined through observation and scientific calculation. This year, the "Shuo" (first day of the first month) of the lunar month to the "first day of the new year" of the first month coincides with the small moon, so the Chinese New Year's Eve is omitted. It is also understood that the next Spring Festival without the Chinese New Year's Eve will appear in 2011-2012 and 2012-2013.

It's not just this year, hehe

This is related to the arrangement of the number of days in the lunar month, and it is normal for this year's Spring Festival to not have the Chinese New Year's Eve.

This year's Spring Festival does not have the Chinese New Year's Eve, because this year is a leap year, and his days will change compared to other years, so there is no big year 30.

Because according to the calculation of time, this year's wax moon is a small month, only 29 days, so this year's Spring Festival is not a big year 30, and the day 29 is Chinese New Year's Eve.

The 2023 New Year has a Chinese New Year's Eve.

The last day of the lunar month is Chinese New Year's Eve, due to the particularity of the lunar calendar, the New Year may be on the 29th or 30th, and the Spring Festival in 2023 will have the 30th of the Chinese New Year's Eve, which will be on January 21 of the Gregorian calendar. This is related to the big and small months, and if it coincides with the big month, there are thirty days. The moon is only twenty-nine days.

The December of the lunar calendar in 2023 happens to be the big moon, so the thirtieth day of the lunar month is the Chinese New Year's Eve.

The Spring Festival is usually a few days in everyone's mind, because it is accompanied by a holiday. It is also the New Year in the traditional sense, also known as the New Year, the New Year, the New Year, the New Year, the New Year, the New Year, etc., is a very important reunion festival in our country, with the meaning of saying goodbye to the old and welcoming the new. The so-called plan of the year lies in spring, and the first day of the first lunar month is the first day of the new year, representing the beginning of the recovery of all things and full of hope.

Various activities for the Spring Festival

During the 2023 Spring Festival, everyone will definitely hold a variety of activities, the purpose of which is to welcome the arrival of the new year of the Mori Rent Tomb. During the Spring Festival, we will definitely paste the Spring Festival couplets, but also paste the word blessing, every door in the home will be pasted Spring Festival couplets, there will be a lot of auspicious words written on it, meaning that the new year, the family can usher in good luck and blessings, family members can make their wishes come true, everything goes well, and have a happy and happy life.

On the night of the Spring Festival, the whole family will sit together to make dumplings to eat, which means that the whole family is reunited, happy, and I hope that in the new year, the feelings between family members will become closer, and they can be considerate and caring for each other, and there will be no quarrels because of small things. During the Spring Festival, the elders in the family will also give red envelopes to the children, expressing their infinite care and expectations for the children, hoping that they can grow up healthy and strong in the new year and achieve good results in their studies.

2023 will have the Chinese New Year's Eve.

The Chinese New Year's Eve is what we often call Chinese New Year's Eve, and according to the calendar, 2023 will have a Chinese New Year's Eve. According to the old rule, the New Year begins with firecrackers on the evening of the thirtieth day, and ends on the sixth day of the tenth month, and the New Year is over. Fifteenth is the Lantern Festival, and the national TV station also holds a Lantern Festival party, guessing lantern riddles, and everyone also likes to watch the Lantern Festival party.

In the rural areas, the peasants were not busy, and before the 15th Five-Year Plan, there were also some village offices playing in the chain bureau, dancing dragon lanterns, playing dry boats, stepping on stilts, twisting Yangge, and so on.

There are 30 in the Spring Festival every year, and when there is no 30, 29 is regarded as 30. If the cherry blossoms fall between the first day of the lunar month of one year and the first day of the first lunar month of the following year, there is no Chinese New Year's Eve. For example, 2022 coincides with the small moon, there will be no Chinese New Year's Eve, but from 2023 to 2024, the Chinese New Year's Eve will come back.

Yes.

The last day of the lunar calendar every year is called the 30th day of the Chinese New Year's Eve, although sometimes the last day of the year is not the 30th day of the lunar calendar, but the 29th day, but because of the 30th most, this day is called the 30th day of the Chinese New Year's Eve in traditional Chinese customs. Therefore, there is a "Chinese New Year's Eve" every year, but not every year there are 30 days of wax moon.

Chinese New Year's Eve is the last night of the year. The last day at the end of the year is called "dividing the year", which means that the old year is divided here and the new year is replaced. Remove, that is, the meaning of removal; Xi refers to night.

Chinese New Year's Eve is the meaning of the night of the year, also known as the big Chinese New Year's Eve, Chinese New Year's Eve, New Year's Eve, etc., which is the last night of the year. Chinese New Year's Eve is a day to remove the old cloth and renew the new, reunite the family, and worship ancestors, and is the same as the Qingming Festival, the July Half Festival, and the Chongyang Festival. Chinese New Year's Eve is of special significance in the hearts of the Chinese people, and on the most important day at the end of the year, wanderers who are far away are also rushing home to reunite with their families, and on Chinese New Year's Eve, they will bid farewell to the old year and welcome the new year.

1. There is no year: "What needs to be clearly told to everyone is that the last day of the lunar calendar is not the Chinese New Year's Eve every year, and this is not something that the state can uniformly stipulate." Because whether there is a Chinese New Year's Eve every year is calculated according to the lunar calendar, if the lunar calendar calculates that there is a Chinese New Year's Eve, it is the last day, if not, but the same Chinese New Year's Eve will also be advanced.

2. It coincides with a small month: The months in the lunar calendar in China are arranged according to the cycle of the moon's waxing and waning, and the average length of a synodic month is not an integer, but 29 days, 12 hours and 44 minutes (days), but the number of days in a month can only be expressed as an integer, so sometimes it is 29 days in a small month, and sometimes it is 30 days in a big month. If the first day of the first month of a certain year coincides with the first month of the next year, there is no Chinese New Year's Eve.

For example, 2022 coincides with a small month, so there is no Chinese New Year's Eve, but 2023 and 2024 coincide with a big month, so these two years have Chinese New Year's Eve.

3. Relatively rare: In people's impressions, days without Chinese New Year's Eve seem to be rare, because the average month length is slightly more than the day, so the number of occurrences of the big month is slightly more than the small month each year, which leads to the lunar year with Chinese New Year's Eve is more than the lunar year without Chinese New Year's Eve.

This year's Chinese New Year's Eve is not the thirtieth day of the Chinese New Year's Eve, because the spine is also divided into large and small months in the lunar calendar, with 30 days for the big month and 29 days for the small month.

The lunar calendar is calculated based on the waxing and waning of the moon, which is known in astronomy as the "synodic month". The first day of each lunar month is the New Year's Day. From "Shuo" to "Wang" macro, and then to the next "Shuo", a cycle is about a day, so the calculated number of lunar months is either 29 days in the small month, or 30 days in the large and infiltrating months.

And this year's wax moon coincides with the small moon, with only 29 days, so there is no Chinese New Year's Eve.
