cyclothymic temperament (characterized by rapid, frequent swings between sad and cheerful moods), is significantly higher in those born in the summer, in comparison with those born in the winter. Those born in the winter were significantly less prone to irritable temperament than those born at other times of the year.
Influence on medical conditions
The season in which babies are born can have a dramatic effect on their future risk relating to the development of conditions such as neurological disorders, including seasonal affective disorder, bipolar depression, schizophrenia and type I diabetes.
First, which month has the least birthdays? The data comes from the Centers for Disease Control and Prevention and the Social Security Administration. The rarest month to be born in is February, making Aquarius the rarest zodiac sign. February is the shortest month of the year, even with a leap year.
July through October tends to be the most popular birth months in the United States.
While October babies have the highest risk of disease among all birth months, they don't let that stop them from living very long lives. According to a 2011 study of over 1,500 centenarians (or people that live to be 100), babies born between September and November live the longest.
Summer babies have some of the same hyperthymic characteristics as spring babies, but that can be offset by cyclothymia — rapid cycling between high and low moods. Still, that's probably not a warning sign of bipolar disorder; bipolar diagnoses are lowest among babies born in August.
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.
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.
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”.
They're rare
December babies are rare, particularly if they were born Dec. 24 or Dec. 25, which are the rarest of all birthdays.

In Australia, the average age for having a first child is 30 years old. The range of age for first-time motherhood in Australia is 25-45 years old. Late motherhood is very common in Australia, with work and financial considerations being key factors here.
However, the birth year's temperature might be not related with birth-sex because gender is determined in the initial stage of the pregnancy. It is well known that the gender can be detected after 20 weeks of pregnancy. Hence, the birth season's related factors cannot affect the gender.
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.
How Big Are Newborns? Newborns come in a range of healthy sizes. Most babies born between 37 and 40 weeks weigh somewhere between 5 pounds, 8 ounces (2,500 grams) and 8 pounds, 13 ounces (4,000 grams). Newborns who are lighter or heavier than the average baby are usually fine.
cyclothymic temperament (characterized by rapid, frequent swings between sad and cheerful moods), is significantly higher in those born in the summer, in comparison with those born in the winter. Those born in the winter were significantly less prone to irritable temperament than those born at other times of the year.
If your July baby is born between July 1 and July 22nd then they are a Cancer, which is the cardinal water sign and is represented by the crab. If your baby is born between July 23rd and 31st then he or she is a Leo.
Those born in September are, apparently, the smartest out of the entire year. According to Marie Claire, a study published in the National Bureau of Economic Research found that there's a clear correlation between the month during which you were born and how smart you are.
The study found that first-born siblings are more likely to survive to 100 years when compared to later-born siblings (odds ratio [OR] = 1.77, 95% confidence interval [CI] = 1.18–2.66, p = 0.006).
The rarest month to be born in is February, making Aquarius the rarest zodiac sign. February is the shortest month of the year, even with a leap year. Conception would have happened the previous May.
The median age (half are younger and half older than this age) of New Zealand women giving birth was 30 years in 2017. In comparison, the median age of women giving birth in the 1970s was 25 years.
