Careful friends will find out when they flip through the calendar
May 22 is the last day of the fourth month of the lunar calendar
But May 23 did not usher in the lunar month of May
It's "Leap April"
Why is the leap month of April followed by the leap month of April?
Zhao Zhiheng, an expert in astronomy education and director of the Tianjin Astronomical Society, explained that in the solar calendar, the earth orbits the sun for a return year, with 365 days in the usual year and 366 days in leap years. The traditional lunar calendar in China is based on the cycle of changes in the moon's circle, with 12 months being 354 days or 355 days, which is 11 days less than the solar calendar year.
In order to solve the contradiction between the two, the ancients adopted the method of setting a "leap month". The current lunar calendar "leap" method is "nineteen years and seven leaps", every 2 to 3 years, it must be added by 1 month, the increase of this month is called "leap month".
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. If there is only solar terms in a month and no mid-breath, this month is called the "leap month" of the previous month.
May 20, 2020, the 28th day of the fourth month of the lunar calendar, is the "small fullness" of the middle gas, and then one month later, the first day of the fifth month of the lunar calendar on June 21 is the next "summer solstice", and this month (May 23 to June 20) has only one solar term "mango seed", which is set as the "leap month". Because it follows April, it is called "Leap April".
As a calendar phenomenon, "leap April" is relatively rare, generally 8 or 11 years apart, and the longest interval is 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).
Two April months, what is the impact on life?

The Year of the Rat in the lunar calendar is also a leap year
There's a "leap April"
There are 384 days in total throughout the year
This is from January 25, 2020 to February 11, 2021

Some netizens found
There are 13 lunar months in the lunar year of the rat
Wouldn't it be a month longer?
Do I want to pay an extra month's salary?
Someone immediately replied sensibly:
Don't think about it
Wages are calculated according to the solar calendar!
Someone will ask
"Two Aprils, what impact will it have on our lives?"
"The impact is great!"
