[Scientific calculation method of boys and girls] How to calculate the number of boys and girls born every year?
Male-female algorithm
The specific algorithm of the Half Moon Secret Method is as follows:
1. Pregnant women are single and pregnant for one month at the age of one, or pregnant for two months at the age of two, and the baby is a girl.
2. Pregnant women are single and pregnant for one and a half months, or pregnant women are pregnant for two and a half months and give birth to boys.
3. Pregnant women are single for one year and pregnant in the second half of the month, or pregnant women are two years old and pregnant in the second half of the month, giving birth to boys.
20 18 scientific calculation method for boys and girls; Husband and wife algorithm; The couple algorithm needs to refer to the imaginary age of the couple and the lunar month when the woman is pregnant. It should be noted that the nominal age of husband and wife should be specific to the nominal age of the first day of the last menstruation before pregnancy. The lunar month of pregnancy should also be specific to the lunar month where the first day of the last menstruation before pregnancy is located. With these three figures, we can predict the birth of boys and girls in detail.
1. Three numbers, two even numbers and one odd number will give birth to a girl.
2. Three numbers, one even number and two odd numbers will give birth to a boy.
If all three numbers are even, a boy will be born.
If all three numbers are singular, a girl will be born.
20 18 scientific calculation method of boys and girls The Qiang nationality has a long history and is an ancient nation in China. Qiang people also have their own algorithms for giving birth to boys and girls. Qiang culture believes that children are the product of both parents, so this algorithm needs to use the birth dates of both father and mother and the specific pregnancy month of the mother.
The specific algorithm is: male (year of birth+month of birth+birthday)+female (year of birth+month of birth+birthday)+month of pregnancy-19, the number of visible digits, even mantissa means girls, odd mantissa means boys.
For example, the existing expectant mother Xiaoyou was born in 1989 12 15, and the prospective father Xiaomi was born in 198 15 on May 24th. The expectant mother Xiaoyou was pregnant in June. According to these figures, we can use the Qiang algorithm to calculate:
{(8 1+5+24)+(89+ 12+ 15)+6}- 19=2 13
The mantissa of the number is 3, which means that Xiaomi and Xiaoyou will have a baby boy.
The ancient method of identifying the sex of the fetus: algorithm: the actual age at the time of pregnancy plus the month of the last menstruation adds up to an even number, giving birth to a son. On the other hand, it is a daughter. Formula: 7749, ask when there is a sound, subtract the birth mother's age and add 19. Results: If the number is even, it is a girl; Odd numbers are boys.
20 18 The algorithm of Hanshu, a scientific method for calculating boys and girls, is said to have originated from Hanshu and was calculated by a man named Cai Wenjun in Han Dynasty according to the orientation of human medicine, heavenly stems and earthly branches and gossip. This method once helped Liu Pingdi successfully predict the birth of boys and girls, so it has always been regarded as a secret treasure, buried in the ancient tombs of the Han Dynasty. The algorithm of Hanshu hides the mystery of July 7th, and the specific algorithm can be summarized in one sentence: "When did asking for the moon have July 7th forty-nine? Not including the mother's birth year, plus 19 strange men and women. " That is to say, if you add 49 to the number of pregnant months of the pregnant mother, subtract the age of the pregnant mother, and finally add 19, the odd number is a boy and the even number is a girl.
It should be noted that the pregnant month of a pregnant mother should refer to the lunar calendar rather than the Gregorian calendar; The age of pregnancy should refer to the nominal age of the pregnant mother on the day of conception.
