What is the accuracy of a Chinese birth chart?
Conclusion. Based on the month of conception and maternal age at delivery, the Chinese birth calendar claims to be 93-99 percent accurate in predicting infant gender. The accuracy of fetal gender prediction based on the Chinese birth calendar was no better than a coin flip in this big delivery dataset.
What is the accuracy of the Chinese birth calendar?
ANN ARBOR, MI
If you’re one of the many expecting parents who has used one of the increasingly popular online Chinese calendar charts to forecast your baby’s gender, a University of Michigan epidemiologist advises against painting the nursery pink or blue.
The so-called Chinese lunar calendar method of predicting a baby’s sex is no more accurate than flipping a coin, according to Dr. Eduardo Villamor of the University of Michigan School of Public Health and colleagues in Sweden and Boston.
“We didn’t set out to debunk any myths with this research. Villamor explained, “We were merely intrigued about it.” However, based on our findings, I would not put any faith in these projections.
Villamor and his colleagues looked at 2.8 million Swedish birth records between 1973 and 2006 to see if the Chinese lunar calendar system was accurate. The method entails converting the mother’s age and the month of conception into Chinese lunar calendar dates, which are then entered into a chart that purports to predict the baby’s gender.
Conversion tables and Chinese birth charts can be found on a variety of websites, and they are becoming increasingly popular. According to one of the websites, the Chinese lunar calendar technique is based on an ancient chart that was buried for about 700 years in a tomb near Beijing.
“The whole idea appears to be illogical. According to Villamor, an associate professor of epidemiology and environmental health sciences at the School of Public Health, “there is no information on the rationale for the chart, and we couldn’t think of a scientific basis for it.” “We attempted to keep an open mind despite our skepticism and simply evaluated the data to see if there was anything to it. There isn’t any such thing.
According to some Chinese lunar calendar websites, accuracy rates of up to 93 percent are possible. When Villamor and his colleagues compared Swedish birth data to the predictions of the charts, they discovered that the Chinese charts were around half of the time correct? the same chance of agreement as if you flipped a fair coin
“The accuracy of the Chinese lunar calendar approach for predicting a baby’s sex leaves a lot to be desired, according to the authors, who published their findings in the journal Paediatric and Perinatal Epidemiology in May.
“We conclude that the CLC approach is no better than throwing a coin in predicting a baby’s sex, and we advise against painting the nursery based on the results of this method, according to the authors.
Sven Cnattingius and Tobias Svensson of the Karolinska Institute and Hospital in Stockholm, as well as Louise Dekker of the Harvard School of Public Health, were among the study’s authors.
Villamor’s principal research focuses on studying dietary factors of mother and child health utilizing epidemiologic methodologies.
How can I figure out what month it is on the lunar calendar?
The length of time it takes for the Moon to go through each of its phases (new moon, half moon, full moon) and then return to its original location is measured in lunar months. The Moon completes one lunar month every 29 days, 12 hours, 44 minutes, and 3 seconds.
You may have heard that the Moon completes one orbit around the Earth in only 27.3 days. So, why is a lunar month longer than the Moon’s orbit by more than 2 days?
A lunar month is the length of time it takes for the Moon to transition from one phase to the next, such as a new moon. To put it another way, the Moon must return to the point in its orbit where the Sun is in the same position as us. The Moon has to catch up a little bit on each orbit because it orbits the Sun with the Earth as part of its orbit. Each orbit of the Moon takes 2.2 days longer to catch up.
What are the colors of the zodiac signs?

Which month is the most common for boys to be born?
The ratio declined dramatically in the second half of 2007 compared to the first half, which is unsurprising considering that the birth ratio is typically higher in the first half of the year.
In general, people give birth to slightly more boys than girls, and more boys are born in the early spring and summer months in the United States than in the fall and winter months. The causes behind this seasonality remain a mystery.
More crucially, the research discovered that the reduction in the second half of 2007 was statistically significant when compared to the previous year and “nearly significant” when compared to the year before, implying that the start of the recession had an impact. (Though the recession technically began in December 2007, warning signals such as falling housing values, downgraded bonds, and bankruptcies began months earlier.)
Looking at our graph above, it appears that the ratio was also smaller in later years, which might or could not be related to economics.
The Big Crunch took a different approach to the same data, smoothing down the variance with rolling averages. A three-month average reveals the seasonal volatility in the ratio more clearly, while a yearlong average reveals a significant fall in the 1 1/2 years after the recession peaked.
Is it possible to have a girl child?
Remember: There’s no proof that altering your diet or timing your intercourse will result in a female baby.
There is only one surefire way to conceive a girl, and that is through a procedure called sex selection. This method of in vitro fertilization (IVF) entails implanting a girl or boy embryo into the uterus of the mother. This approach, on the other hand, is costly and, in some cases, unlawful.
Other approaches for sex selection have been utilized by households. To improve your odds of having a boy or girl, the majority of them rely on sex timing.
Shettles method
Dr. Landrum Shettles created the Shettles technique in the 1950s. According to this strategy, you should have intercourse 2 to 4 days before ovulation to boost your chances of having a daughter.
This approach is based on the idea that in acidic conditions, girl sperm is stronger and lasts longer than boy sperm. Only female sperm should be left by the time ovulation occurs.
Shallow penetration is also recommended by Shettles to give girl sperm an advantage. Sperm can enter the female body at the vaginal opening, which is a more acidic environment, in this fashion. This also aids the survival of female sperm.
According to Shettles, this procedure has a 75% success rate in producing a daughter. However, there is currently no scientific evidence to support the Shettles method’s effectiveness.
Whelan method
The Whelan technique, created by Elizabeth Whelan, is another option. This method is similar to Shettles’ in that both assume that timing is a key component in determining sex.
To conceive a girl, Whelan’s approach recommends having sex two or three days before ovulation or on the day of ovulation. Male and female sperm operate differently at different stages in a woman’s menstrual cycle, which is why the timing is important.
At this time in the cycle, sperm with X chromosomes (female sperm) are more likely to fertilize an egg. Girl sperm has a better chance of surviving when you have sex closer to ovulation or on ovulation day.
According to Whelan, this procedure has a 57 percent success rate in conceiving a daughter.
Babydust method
Author Kathryn Taylor came up with the Babydust approach. She also discusses the timing and frequency of intercourse in order to maximize the chances of producing a daughter.
You’ll track your luteinizing hormone (LH) twice a day, once in the morning and once in the evening, for three months before attempting to conceive with this method.
You can comprehend trends in your menstrual cycle since a surge in this hormone suggests that ovulation will occur within the next 12 to 48 hours. You can better predict ovulation this way.
“Testing at least twice a day is crucial,” according to Taylor’s book, “because if you just test once a day, you may discover and record your LH surge much later than it actually occurred, or, even worse, you may miss your surge entirely.”
The Babydust approach recommends having intercourse two or three days before ovulation after tracking the hormone for three months. The goal is to give female sperm an advantage once more. The boy sperm will no longer be viable by the time the egg arrives.
What are your chances of having a female child?
Neither parent has the authority to make a decision.
Almost everyone has a 50 percent chance of having a boy and a 50 percent chance of having a girl when they get pregnant.
What we can say is that a baby’s gender is determined by the sperm of the father. Half of his sperm will result in a boy and half will result in a girl. The baby’s sex is determined by which sperm reaches the egg first.
In an ideal world, everything would be decided by chance.
Both sperm types would have an equal chance of getting to the egg initially. Each sort of egg would have an equal chance of growing fully into a baby if fertilized.
However, as you are aware, the world is not ideal.
Certain things can have an impact on a child’s sex.
As you’ll see in the video below, there’s a lot more proof of this happening in animals, but it also happens in humans.
Each year, slightly more boys than girls are born in humans. But it’s difficult to pinpoint why this occurs.
According to one old notion, sperm with the smaller Y chromosome are slightly faster than sperm with the larger X chromosome. As a result, Y-carrying sperm may have a better chance of reaching the egg first. However, it turns out that this isn’t the case. Sperm with a Y appear to swim at the same rate as sperm with an X.
