There are still many surprises this year, such as two lunar "April"! A friend wants to know "Two Aprils, what impact does it have on our lives?" ”
"The impact is great!"
"Leap April", only 8 times in this century!
On April 23, the first day of April in the year of the rat in the lunar calendar, and after this April, there is a "leap April" followed by two lunar "April" for a total of 59 days.
Astronomical experts say that as a calendar phenomenon, "leap April" is relatively rare, generally 8 or 11 years apart, and the longest appears once every 38 years. In the 21st century, there are 8 years of "leap April", the most recent one is 2012 (nongchen year), and the next time is 2058 (penta yin year).
Astronomical experts explain that the leap month appears in the lunar year because the traditional lunar calendar adopted by China for thousands of years is actually a luni-yang calendar, taking into account both the solar return year directly related to the sun and the lunar synodic month that changes phase with the moon. The average of a synodic month is 29.5306 days, and the total number of 12 synodic months is 354 days or 355 days, which is about 11 days different from the return year (about 365.25 days), and the 3-year accumulation has exceeded one month.
The method of adjustment is to arrange 13 months in some years, and there are two identical months, called "leaps". The rule of "leaping" is based on the twenty-four solar terms. The lunar calendar uses twelve mid-qi as a symbol of twelve months, that is, each month has a certain mid-qi. The leap month of the lunar calendar had different arrangement methods in ancient times, but from the Han Dynasty onwards, a leap month was gradually formed, and the month that did not contain mid-qi was called the leap month of the previous month. The "leap month of April" in the year of the rat in the lunar calendar is the leap month of April of the previous month. In that month, only the "Mangsang" solar terms, while the middle "summer solstice" falls on the first day of the fifth month of the lunar calendar.
This "leap April" of the Year of the Rat begins on May 23 in the gregorian calendar and ends on June 20 in the gregorian calendar.
In addition, due to the impact of the leap month, this year's Dragon Boat Festival also came later, until June 25.
The Year of the Rat involves an extra month of shifts
The Gregorian calendar year 2020 is a leap year with 366 days a year; the year of the rat in the lunar calendar is also a leap year, with a "leap April", a total of 384 days in the year, from January 25, 2020 to February 11, 2021. That said, 2020 is a leap year.
There are 13 lunar months in the lunar year of the rat, which requires an extra month of classes.
Moreover, this year's Mid-Autumn Festival is the same day as the National Day.
