Why is the year of the pig only 354 days a year? 384 days in 2020

Now it's the month of wax, and it's getting closer to the Spring Festival. A few days ago on Weibo, people said that there were only 354 days in 2019. They didn't pay attention at that time. Now think about it, it's a full 11 days less than usual. When they are wondering, they say that there are nearly 384 days in 2020, which makes people more confused. What's the reason?

Why is the year of the pig only 354 days a year?

Everyone is very concerned about the coming year of the pig. Recently, we have found a problem that the year of the pig is only 354 days, which makes many people wonder how it is.

In fact, many people do not know that the Chinese Zodiac year is the lunar year, and the general real pig year is calculated from the beginning of the first month, specifically to the year of the pig in the Chinese calendar. The first day of the first lunar month in 2019 is February 5, so all the children born between February 5, 2019 and January 24, 2020 belong to pigs. In this period, the coming year of pigs just has 354 days, so people say that the year of pigs is only 354 days. The year of pig is the year of gengzi mouse in the lunar calendar, that is, 2020, with April leap, 19 days more than the normal year, so there are 384 days in total.

So why is there another 384 days in 2020?

There is a folk saying that "four years a leap, one hundred years no leap, four hundred years leap again". In the Chinese calendar, 2019 is a normal year, while 2020 is a leap year, in which there is another leap April, so there are 384 days in 2020. There are three universal calendars in the world: the lunar calendar, the solar calendar and the Yin Yang calendar. The lunar calendar is calculated according to the law of the moon's round and missing changes. There are 12 lunar calendars in a year, a total of 354 days. The solar calendar is based on the law of the earth's rotation around the sun, so the year is 12 months, with 365.24 days in total, so the lunar calendar year is about 11 days less than the solar calendar.

In order to coordinate the 'error' between the solar calendar and the lunar calendar, the ancients also learned about this problem, so they invented the calculation method of 7 leap years in 19 years, which means that 7 leap years are added in every 19 lunar years, and another leap month is added in the leap year, so there are 383 to 385 days in the 13 months of the leap year, while the average lunar year has 353 to 355 days.

The year 2018 and 2019 of the lunar calendar are both normal years, with a total of 354 days in 6 big months (30 days) and 6 small months (29 days). The year 2020 is a leap year, with a leap April added, so it's 384 days.

As you all know, the Chinese New Year's Eve in 2019 is the first spring. As the saying goes, "seven years will never see a leap in September, and a hundred years will never see a spring in the first year". It is said that the year of 2019 pig is a good plus, which is really a good year for a hundred years.
