Before planning for a baby boy or girl in 2021 or 2022, we should know what the meanings are behind the year of 2021 and 2022.
2021 is the year of the White Metal Cow. The Chinese New Year Day of Cow year is on February 12, 2021. 2022 is the year of the Black Water Tiger. The Chinese New Year Day of Tiger year is on February 1, 2022. The Chinese New Year Day is the first lunar day of the first lunar month. That means Chinese New Year Day is determined by the Chinese Lunar Calendar. Chinese Zodiac Signs are determined by Chinese Astrology Stem-Branch Calendar. If a baby is born on or after February 3, 2021 and before February 4, 2022, then the Chinese zodiac sign is Cow. If born after February 4, 2022, then the Chinese zodiac sign is Tiger.

The Fact of Chinese Baby Gender Prediction Chart
How accurate is the Chinese Baby Gender Prediction Chart? The Gender Prediction Chart is a statistics data sheet. It's not very accurate. But it's much better than 50/50 guessing. According to our survey raw data, it's close to 70% accuracy. Why we want to reference it if not accurate? If you understand the meaning behind the Gender Prediction Chart, then you will know there is a value there.
Many families in the world prefer boy babies. According to the 2017 data bank from United Nations Population Division shows the sex ratio of male births per female births is 1.073. The ratio at China is 1.15, India is 1.107, Armenia 1.129, Azerbaijan 1.125 and Vietnam is 1.097. The average sex ratio from 1997 to 2017 is about 1.075. The birth data at US Centers for Disease Control (CDC), 1977663 baby boys and 1887091 baby girls born in 2017. The US sex ratio between males and females is 1.048.
According to World Health Organization (WHO) data, the natural sex ratio between males and females at birth is 1.05 from 1990 to 2010 without counting sex-selective abortion and gendercide. That means that at birth on average, there are 105 males for every 100 females. This number is close to US sex ratio. We have extra 5% chance to have baby boys than girls.
Woman Conception Chinese Lunar Month

Woman's Conception Month is the
Blue is for boy and pink is for girl in the chart.
The Chinese Baby Gender Prediction Chart has 336 prediction months from age 18 to 45. The boy predictions are 164 and the girl predictions are 172. The sex ratio of male per female is 0.953. There is 10% difference comparing with the WHO's ratio. This cannot tell Chinese Baby Gender Prediction Chart is totally wrong. It's possible that the conception months most women chose have more chances to deliver baby boys.
|Lunar Month||Near Zodiac||Proximity Month||Boy Counts|
If we count for boy blue box in the Prediction Chart for all month columns, we find that January, February, March and April have higher boy counts. This probably is something to do with Chinese I-Ching Hexagrams. I-Ching states the natural phenomena of our universe, and then applies it on people, family and the nation relationships. The nature rule of the universe (Dao) is Yin and Yang. I-Ching uses the symbol of broken bar as Yin and the solid bar as Yang. Yin is female or cold. Yang is male or hot. One trigram has 3 bars and one hexagram has 6 bars. Yin-Yang and Hexagram can apply on the months. Each month has its own hexagram. December has the first Yang growing from the ground. January has two Yangs on the ground. February has three Yangs on the ground. March has four Yang bars and April has five Yang bars. Full six Yangs are in May. In June, Yang completely dies and Yin is born.
Yang is connected to the boy. The energy of Yang grows from December to May. The energy of Yin grows from June to November. The first Yang of December is too weak. The full Yang of May will die soon. The energy of Yang is growing strong from January to April. That means the conception months in January, February, March and April are favorable to have a baby boy. Summer season is favorable to the baby girl.
Baby Sex Ratio at Birth in China
Do the seasons affect gender of babies? US National Center for Biotechnology Information published a study of The Association between Season of Pregnancy and Birth-Sex among Chinese in 2014. It stated that Chinese mothers pregnant in summer or winter had a higher probability of delivering girls than those pregnant in spring. The statistic data was from 3051 Chinese children who were born between 1 January 2006 and 31 November 2008. They had very good high-quality birth data from the parents. Among 3051 children, there were 1582 boys (51.8%), and 1469 girls (48.2%). The Chinese sex ratio of boy per girl is 1.0769 during 2006 to 2008. The following is the monthly sex ratio chart.
We can see December, January, February, March and April are above average.
Those months show higher boy counts in the Chinese Baby Gender Prediction Chart.
That means the survey data of baby gender in Ching Dynasty had the similar result to China birth data between 2006 and 2008. The spring time in China is February, March and April. The energy of Yang growing months from December to April are favorable to have a baby boy in China.
What Influences the Gender of a Baby?
The gender of a baby is determined by mother and father's chromosomes.
If the (female) sperm carrying the X chromosome fertilizes the egg, a girl will be conceived.
If the (male) sperm carrying the Y chromosome fertilizes the egg, a boy will be conceived.
The sperms with Y chromosome travel faster and have a shorter life span than the ones with X chromosome.
Base on the chrematistics of X and Y chromosomes, people look for the factors to manipulate the chromosomes. There are a variety of theories about influencing the sex of a baby. They said something to do with parents' diet, body's acid and alkaline levels, timing of conception depending on ovulation, weather temperatures, seasons, regions, hormones, stress, blood pressure, etc.

Compromise 2021 Chinese Lunar Months with Zodiac Months
The Chinese Baby Gender Prediction Chart uses Chinese Lunar Calendar to predict baby gender. Do you know Chinese Lunar Calendar needs 7 extra lunar months in 19 years? Chinese Lunar Calendar needs a year of 13 lunar months around every three years in order to synchronize the cycle of the sun. That means you will see a leap month (intercalary month) every three years.
There are only 12 months in the Chinese Baby Gender Prediction Chart. 2020 Chinese Lunar Calendar has 13 lunar months, extra leap 4th lunar month in China time zone. The total of lunar days is 4th lunar month is 59. This becomes an issue to apply on the Baby Gender Prediction Chart. Some people suggested that the days in the first half of leap 4th month should group into the 4th month. The days in the second half of leap 4th month treat in the 5th lunar days. Both 4th and 5th lunar months have around 44 lunar days. A normal lunar month has 29 or 30 days. Some people won't accept this approach.
While doing the survey for Chinese Baby Gender Prediction Chart, a few of women emailed us and said the Chinese Baby Gender Prediction Chart is accurate; they tried many birth data of the relatives using the solar Gregorian months, not the Calendar lunar months.
People wonder the Chinese Baby Gender Prediction Chart should use the Chinese Astrology Zodiac (Stem-Branch) Calendar, which is a solar calendar. According to the theory of the Chinese Lunar Calendar, the first zodiac month is the Tiger month, which is equivalent to the first lunar month. Rat month is corresponding to the 11th lunar month and Cow month is corresponding to the 12th lunar month. In the way, we don't have the trouble of leap months.
We compromise the Chinese Lunar Months with Chinese Zodiac Months in the following chart. The days in the lunar month and also in the corresponding Zodiac month are the new revised lunar months. If a woman wants to use the suggestion of Chinese Baby Gender Prediction Chart to conceive next baby, then she should use the revised lunar months.
