Self-test method for boys and girls

The most accurate way to measure boy and girls.

One:

Lunar month of pregnancy+lunar birthday month of pregnant women-imaginary age of pregnancy+19=, and the mantissa of the result is a single boy and a double girl.

Example: The month of pregnancy is June of the lunar calendar, the month of pregnant women's birthday is July, and the nominal age is 29 years old. The calculation method of giving birth to boys and girls is 6x6+7-29+ 19=33, and the mantissa of the result number is single, indicating that it is a boy.

Second:

The sum of the father's age at the time of pregnancy+the mother's age+the number of months of pregnancy (both are real years) is divided by 3, and the result is an integer, the singular is a boy, and even or zero is a girl.

Example: The pregnant father is 30 years old, the mother is 27 years old, and the pregnancy time is June. The calculation method for boys and girls is (30+27+6)/3 = 2 1. The mantissa is single, which means it is a boy.

Three:

The sum of the father's age at the time of pregnancy+the mother's age+the number of months of pregnancy (both are real years) is divided by 3, and the result is an integer, the odd number is a boy, and the even number or zero is a girl.

Example: The pregnant father is 30 years old, the mother is 27 years old, and the pregnancy time is June. The calculation method for boys and girls is (30+27+6)/3 = 2 1. The mantissa is single, which means it is a boy.

Four:

Father (year of birth+month of birth+birthday)+mother (year of birth+month of birth+birthday)+month of pregnancy-19=, resulting in a single mantissa and a boy; The mantissa is double. It is a girl. The first half of each leap month follows the previous month, and the second half follows the next month.

Example: The father's birth date is1967 65438+February 15, the mother's birth date is1967 65438+18, and the lunar month when the mother is pregnant is May, so the calculation method of giving birth to a boy and a girl is {(67+/).

Five:

49+ the lunar month when the mother was pregnant-minus the mother's age+19=, the mantissa is single, and it is a boy; The mantissa is double. It is a girl.

Example: My mother was 28 years old when she was pregnant, and she was pregnant in August of the lunar calendar. The calculation method of giving birth to boys and girls is 49+8-28+ 19=48, and the mantissa is double, which means giving birth to girls.

A folk recipe for testing boys and girls.

Formula -7749 method for testing boys and girls. Take 49 as the base, add the month when we are pregnant, then subtract the age of the expectant mother when she is pregnant, and finally see if the number is odd or even, where odd indicates that the baby in the belly is a boy and even indicates that the baby in the belly is a girl. Next, let me give you an example to better understand. For example, if the expectant mother is pregnant at 3 1 year old and 1 month this year, then the calculation method is: 49+1-31= 19, and the number19 is just an odd number, which means that the baby in the mother's womb should be an odd number.
