Is this ancient gender prediction test really 90 pc accurate?

For hundreds of years, an ancient Chinese calendar has been circulating that claims to accurately predict a baby's gender.

The ancient Chinese gender calendar is said to have originated from the Qing Dynasty (between 1644 and 1911 AD), and claims to predict a baby's gender based on the mum-to-be's Chinese lunar age when the baby is conceived and the lunar month of conception. Legend has it that the chart was buried in the tomb of the Chinese royal family approximately 700 years ago. The original calendar is currently kept in Beijing's Institute of Science. A hugely popular method of gender prediction in Asia, many mums swear by its incredible accuracy and use it when trying to specifically conceive a boy or girl. Despite claims that the table is accurate in 90 percent of cases, there have been no scientific studies to validate the calendar's accuracy. If you fancy testing its reliability for yourself, just follow the steps below but be warned because it's really not as easy as it looks... 1. Find your lunar age at time of conception Your age in the chart should be your Chinese age at the time of conception, which is usually one or two years older than your actual age. To find this out, subtract your Chinese lunar birth year from the lunar year you conceived then add one year (told you it was complicated!) 2. Find the lunar month of conception The month of conception in the chart must be the Chinese Lunar Month. You can find this using a Gregorian-Chinese calendar converter online. 3. Pink or blue Once you've established your Chinese age and month of conception, find the correct age across the top of the chart and the month during which your conception occurred down the lefthand side. Then follow the column and row to the intersecting point to reveal your baby's gender. For example, if your Chinese age is 35 and month of conception is December you may well be getting a blue delivery from the stork.
