The year of the ugly ox is only 354 days. Why is it 30 days younger than a mouse?

Today is the seventh day of the first month, and many friends have already started classes. The year of the ox is coming. I wish you all the best in Taurus! Many friends are still immersed in the thick flavor of the year. The People's Daily sent a picture to remind everyone that this year is a special year, and there are many interesting things you may not know.

This is an ugly year of the ox, which lasted 354 days from February 12, 20265438 to October 3 10, 2022. Compared with the Year of the Ox of the previous year in 2009 and the Year of the Ox of the next year in 2033, the difference is 384 days. Why is there only 30 days less in the Year of the Ox this year?

This is because the daily difference of the lunar calendar is ultimately caused by calendar calculation. Now we have three calendars: solar calendar, lunar calendar and yin-yang calendar. In these calendars, the solar calendar is compiled according to the cycle of the earth's orbit around the sun, with 365.2422 days a year; The lunar calendar is compiled according to the change of the moon's lack cycle, and there are 354.72 days in a year.

So we see that the interval between the solar calendar and the lunar calendar is more than ten days, so we see the yin-yang calendar, which is our lunar calendar, including leap months and non-leap months. There will be seven leap months next year, in order to coincide with this time in the solar calendar. So the ancients were also very wise, very wise.

According to the tradition of Yin and Yang, there is no leap month in normal years. This year's ugly ox year is a normal year. So there is a 30-day gap between this ugly year of the ox and the next.

202 1? The beginning of spring? February 3 is still the year of the rat. What's next? The beginning of spring? It's February 4, 2022, the year of the tiger. The year of the ox is just right? Avoid? In these two days after beginning of spring, there were only 23 solar terms.

It is not unusual for spring to bloom or not, and it has no special significance. There will be a leap year every two or three years in the lunar calendar, and there will be one every leap year? The beginning of Spring Festival couplets? Beginning of spring next year or every other year will be a lunar year without solar terms. Statistics show that in 2 1 century 100, double beginning of spring? There are 25 solar terms, but there are only 23 solar terms without beginning of spring, each with 37 years, and there are 24 solar terms in other years.

When setting leap years in the solar calendar, just remember this sentence: leap every four years, not every hundred years, and then leap every four hundred years. Even with such complicated settings, there will still be a one-day delay after about 3300 years.
