What does it mean that 2020 is a double leap year? How many days are there in Shuangchun?
1. What is a double spring year? This means that two solar terms in a year are beginning of spring. The double spring year is a unique phenomenon in Chinese calendar, which is actually caused by the "wrong balance" between the solar calendar and the lunar calendar.
The solar calendar is based on the law that the earth revolves around the sun. The revolution of the earth 1 is 1 year, divided into 12 months, and counted as 365 days (366 days in leap years). The lunar calendar is based on the law of the moon's profit and loss. The orbit of the moon around the earth is 1 month, and a year is 12 months. The actual number of days is 354 days.
China's calendar is based on the cycles of the sun and the moon. In this way, there is a deviation of 1 1 day between the lunar calendar and the solar calendar, so the lunar calendar has a "leap month" to solve the time difference problem of the lunar calendar.
Double spring means that there will be two beginning of spring in the Lunar New Year. The traditional calendar in China is a combination of yin and yang: "Yin" means that the calendar month is based on the new moon (with an average length of 29.5306 days), and the new moon is the first day of each month; "Yang" means that its calendar year is basically based on the Tropic of Cancer, and the first day of the first month (that is, the Spring Festival) is the first day of the first month around the annual "beginning of spring". In the summer calendar1February, the average year is only 354 days or 355 days, and in some years it is only 353 days. A leap month 13 year has 383 or 384 days, and some years have 385 days, which can contain 25 solar terms, so that there is a "beginning of spring" at the beginning and end of each year, which becomes a double spring year.
Double spring years generally appear in leap month years. According to the normal month, the lunar calendar has 24 solar terms in a year, and after the 24 solar terms are replaced, it will enter the next year's solar terms replacement. However, due to the leap month, next year's beginning of spring solar terms will appear on this year's tail. Therefore, the phenomenon of "double spring year" appeared. In fact, this is caused by the current custom system in China that the first day of the new year is the beginning of the new year. In ancient times, people regarded beginning of spring as the beginning of a new year, so there was no such thing as a "double spring year" in ancient times. The "double spring year" is only the result of the "correction" of the yin and yang calendars, and it is a natural product of the solar terms in the calendar, which has nothing to do with good or bad luck.
For example, the first beginning of spring in the Year of the Monkey in 2004 was on February 4, 2004, and the second beginning of spring in the Year of the Monkey was on February 4, 2005, because the Year of the Rooster was only on February 9, 2005, which was a double spring. In 2004, the year of the monkey had a leap in February, which was a "double spring year", and in 2005, the year of the rooster became a "spring-free year". 2004 is the year of double spring. 10 year, 20 12 year, 20 14 year, 20 17 year, and 2020 is a "double spring year".
2. Is the double spring year good or bad, then is it a double spring year? In rural areas, there is a good saying that people regard beginning of spring as the beginning of a year, so there is also a saying in beginning of spring that spring is announced and played. People think that beginning of spring is the beginning and end of a year, but there is no beginning of spring. Because there is no beginning, getting married in a spring-free year will have a bad ending, so people in rural areas call a spring-free year a widow's year. There are two solar terms in beginning of spring in the year of double spring, so people think that yes-men have not only a good start, but also a good ending, whether they get married or start a business. In fact, whether a marriage is happy or not has nothing to do with beginning of spring. Many young couples who got married in years without spring still live a smooth life. On the contrary, many couples who get married in Shuangchun cannot be together forever.
In rural areas, there are many proverbs about the climate and farming in two spring years, such as "fur is as expensive as gold in two spring years", which means that if there are two beginning of spring solar terms in the Lunar New Year, it will definitely be very cold in winter, and people will snap up animal fur clothes for better warmth, and the price of animal fur clothes will double because of people's crazy snapping up. "Two spring and one winter, ten cowsheds and nine empty rooms" means that if there are two beginning of spring in the Lunar New Year, the pests in the field will freeze to death because of the cold winter and heavy snowfall, and the overwintering crops will grow well after the next spring because of sufficient water, so the cows raised at home will be pulled out to do farm work when they are idle, and only the calves will stay at home.
3. According to the old almanac, when were the two beginning of spring in 2020 discovered? In 2020, beginning of spring is on February 4th, that is, the 11th day of the first lunar month, which is earlier, and it was already spring before the Lantern Festival. The next beginning of spring is in the lunar calendar, on the 22nd day of the twelfth lunar month in 2020. Although it is near the end of the year, it is still in 2020.
So there will be two beginning of spring in 2020, which is called "Double Spring Year" or "Second Spring" by the people.
Around the solar terms in beginning of spring, different years have different opinions, including the year of single spring, the year of double beginning of spring and the year without beginning of spring, which respectively represent that there is one beginning of spring, two beginning of spring and no beginning of spring this year.
Because most years are single spring years, single spring years are rarely mentioned, but in double spring, people pay more attention.
"Double" is a big number, and every couple is happy. Newcomers like to get married in pairs. In order to live a good life and be happy in the future, the older generation will ask someone to calculate a good day for marriage, and generally choose the year of beginning of spring to get married, which means good luck and happiness.
In some places, the custom holds that when people get married in double spring, the new couple can live in harmony and happiness, and have many children. However, in some places, the opposite is true. I think it's not easy to get married when there are two beginning of spring in a year. Main spring means "second spring", thinking that getting married this year will lead to divorce and unhappy marriage.
Some folk sayings of "Double Spring Year" are just some beautiful meanings, such as "It's hard to meet Er Quan once a year, but it's hard to make spring in a hundred years", "Three leaps and two jumps, two springs a year", "Two springs a year, and beans are as expensive as gold" and many other proverbs.
There are two beginning of spring in a year, mainly because of different calendars. We have two calendars, the solar calendar and the lunar calendar. In rural areas, the lunar calendar is chosen as a good day for major marriages, weddings, funerals and birthdays.
Therefore, these statements about "Double Spring Year" have no scientific basis, but the wishes of the older generation for a better life.
