This study discusses the relationships between the Chinese Baby Gender Prediction Chart and sex ratio at birth by different countries and seasons.

We also create a revised Baby Gender Calendar to solve the problem of the Chinese lunar leap month.

Plan for Baby Boy or Girl in 2019 or 2020

Before planning for a baby boy or girl in 2019 or 2020, we should know what the meanings are behind the year 2019 and 2020. 2019 is the year of the Brown Earth Pig. The Chinese New Year Day of Pig year is on February 5, 2019. 2020 is the year of the White Metal Rat. The Chinese New Year Day of Rat year is on January 25, 2020. 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 the Chinese Astrology Stem-Branch Calendar. If a baby is born on or after February 4, 2019, and before February 4, 2020, then the Chinese zodiac sign is Pig. If born after February 4, 2020, then the Chinese zodiac sign is Rat. The Zodiac signs are nothing to do with the Chinese New Year.

That means the conception months in January, February, March, and April are favorable to have a baby boy. The Summer season is favorable to the baby girl.

Baby Sex Ratio at Birth in China

Do the seasons affect the 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 from 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 the Ching Dynasty had a similar result to China birth data between 2006 and 2008. The season of Spring in China is February, March, and April. The energy of Yang growing months from December to April is favorable to have a baby boy in China.

Regions affect Sex Ratio at Birth

Regarding the factors of temperatures and seasons influencing baby gender, different countries reported different results. That tells us regions affect the sex ratio at birth. What we are interested in now is the relationship between months and baby genders by region. The chart below is from the US CDC birth data from 1994 to 2014. The total records are more than 84.8 million.

This chart shows more boys were born in July, August, October, November, and January. Pregnancy lasts for about 280 days or 40 weeks. It's for about nine months. The conception months in October, November, January, February, and April are favorable to have a baby boy in the USA.

The sex ratio at birth of the USA in 2017 is 1.048, below the average 1.07 of the world. Girls like to be born in the USA today. Probably girls have better human rights in the USA. The USA 2017 monthly sex ratio counts are in the following.

Compromise 2019 Chinese Lunar Months with Zodiac Months

The Chinese Baby Gender Prediction Chart uses the Chinese Lunar Calendar to predict baby gender. Do you know the 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 in the 4th lunar month is 59. This becomes an issue to apply to the Baby Gender Prediction Chart. Some people suggested that the days in the first half of leap 4th month should be grouped into the 4th month. The days in the second half of leap 4th month are treated in the 5th lunar days. Both the 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 the Chinese Baby Gender Prediction Chart, a few 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 the Chinese Baby Gender Prediction Chart to conceive the next baby, then she should use the revised lunar months.
