This year is the lunar year of the ox, which starts on February 12, 2021 and ends on January 31, 2022, with a total of 354 days. The last year of the ox in 2009 and the next year of the ox in 2033 have 384 days. Why is the year of the ox less than 30 days this year? Cao Yansheng, director of the Beijing folk custom museum, said that the difference in the number of days in the lunar year was caused by calendar calculation.
We now have the solar calendar, the lunar calendar, and the Yin Yang calendar, which we often call the lunar calendar, three kinds of calendar forms. Among them, the Gregorian calendar is based on the earth's cycle around the sun, with 365.2422 days in a year; the lunar calendar is based on the moon's cycle, with 354.3672 days in a year.
Cao Yansheng, director of Beijing folk custom museumIn this way, we can see that there is a gap of more than ten days between the solar calendar and the lunar calendar, so we have another lunar calendar, that is, our lunar calendar, which involves leap month and non leap month. There must be seven leap months in the 19th year of the lunar calendar, so as to make up this time point with the solar calendar. So we ancients are also very intelligent and intelligent. According to Yin and Yang, there is no leap month in an ordinary year. This year's year of the ugly ox is an ordinary year. The previous year of the ox has a leap month, and the next year of the ox also has a leap month. So we are 30 days away from the next year of the ox.
Not only the number of days is less, this year, the year of the ox, even the solar terms are one less than in previous years. Let's continue to see the expert's explanation.
Cao Yansheng, director of Beijing folk custom museumWe all know that there are 24 solar terms in a year, while there are 25 solar terms with leap moon. The spring begins in the year of the rat, so there are 23 solar terms in the year of the ugly ox.
The "first spring" of 2021 is on February 3, which is still the year of the rat. The next "first spring" is on February 4, 2022, which is the year of the tiger. The year of the ox of xinchou just "avoids" these two first spring days, so there are only 23 solar terms. Experts said that the phenomenon of "double beginning of spring" or no beginning of spring is not uncommon, and there is no special significance. There will be a leap year every two or three years in the lunar calendar, and there will be "double spring" in every leap year. In the next year or every other year after "double spring", there will be a lunar year without solar terms of spring. Statistics show that in the 100 years of the 21st century, there are 25 solar terms in the year of "double beginning of spring" and there are only 23 solar terms in the year without beginning of spring, each with 37 years, and the remaining years are 24 solar terms.
