These two days,
Careful friends will find that when they turn 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?
In the solar calendar, the Earth orbits the Sun as a regression year, with 365 days in a normal 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 2020 in the Gregorian calendar is a leap year with 366 days a year.
The Year of the Rat in the lunar calendar is also a leap year,
There is a "leap April", a total of 384 days a year,
For January 25, 2020 - February 11, 2021,
That said, 2020 is a leap year.
Some netizens found that
There are 13 lunar months in the year of the rat in the lunar calendar,
Wouldn't it be a month longer?
Do I want to pay an extra month's salary?
Someone immediately replied rationally: 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!"
Affected by the "leap April", since then,
The lunar festival in the year of the Gengzi Rat,
Such as Dragon Boat Festival, Tanabata Festival, Chongyang Festival, etc.,
The corresponding date in the solar calendar is compared to last year,
Both will be postponed by 18 days.
Affected by this,
2020 National Day, Mid-Autumn Festival on the same day,
Everyone's expectation of "double section in one"
Ready to come too!
Some netizens found that
People born in the fourth month of the lunar calendar can have more birthdays,
It was a bonus.
