According to real birth data compiled from 20 years of American births, mid-September is the most birthday-packed time of the year, with September 9th being the most popular day to be born in America, followed closely by September 19th.
Nature is designed to favour the conception of boys from September to November and girls from March to May because of an evolutionary mechanism aimed at keeping the overall sex ratio as near to 50:50 as possible, the scientists said.
“The CDC tracks birth data nationwide, and July through October are the busiest birth months, with August typically having the highest number of births.
The most common birthday in Australia is September 17th! The least common birthday (you may have guessed it is) is Christmas Day, the 25th of December. If you are inclined to count leap years in the mix then the 29th February is the least common birthday, but only because they occur once every 4 years.
December 25 (Christmas Day) is the least common birthday, while January 1 (New Year's Day) is the second least common. December 24 (Christmas Eve) also makes the list as the 3rd least common birthday while July 4 (Independence Day) is the 4th least common birthday.
For good reason. In the United States, most births occur between June and early November. Count back nine months, and you'll see that places most conceptions in the fall and winter.
Those that are born in July are either a Cancer or Leo. Cancer birthdays fall between June 21 – July 22, while Leo birthdays fall between July 23 – August 22. Cancer babies are often known for being caring, protective and empathetic.
Only 7.6 percent percent of male babies and 5.5 percent of female babies were in the womb 42 weeks or longer. Males were also 1.5 times more likely to be born at 43 weeks or longer. The researchers noted that the most common reason for prolonged pregnancies is an error in calculating the due date.
Also meaning that December is the least common birth month, with January and February sharing a similarly low birth rate. But what does that tell us? Well for one, March, April and May are the least popular months to get it on, according to this study.
While September might be choc-a-bloc with multiple babies being born on a daily basis, there is also a least common birth month, where only a bunch of babies tend to share it together. And that, unironically, is the month of December, which could stretch a bit into January and February too.
February 3rd is the only day where no one in history has ever been born. Despite much scientific study, there is no explanation for this phenomena. Historically it has been referred to as “the empty day” or “nobody's birthday”.
What is a Golden Birthday? Your golden birthday is when the date of your birth coincides with your age. For example, if you were born on October 8, your golden birthday took place when you turned 8. If you were born on December 21, your golden birthday took place when you turned 21.
Additionally, the golden birthday is considered especially lucky and special since it only occurs once in a lifetime. If you're over the age of 31 and are feeling sad you may have missed your golden birthday, have no fear! Turning the age of your birth year is considered a platinum birthday.
December babies are rare, particularly if they were born Dec. 24 or Dec. 25, which are the rarest of all birthdays.
All human individuals—whether they have an XX, an XY, or an atypical sex chromosome combination—begin development from the same starting point. During early development the gonads of the fetus remain undifferentiated; that is, all fetal genitalia are the same and are phenotypically female.
By most measures of sensory and cognitive development, girls are slightly more advanced: vision, hearing, memory, smell, and touch are all more acute in female than male infants.
Boys are more likely to be born before their due date. After the 40-week mark, however, the odds slightly favor a girl.
What is the rarest girl name? One of the rarest girl names is Elora, because it's low on the popularity charts, but there are several rare girl names including Hadleigh and Ophelia.
