We used Danish data from the years 1911 to 1915 on seasonal infant mortality in the first year of life and found that, according to our model (Eq. 4), infants born in June are the most vulnerable.
In general, individuals born in May through July had the lowest age at death (1984: 75.27+/-0.09 years; 1999: 77.58+/-0.09 years), while those born between October and December had the highest (1984: 75.98+/-0.08 years; 1999: 78.35+/-0.09 years), supporting earlier findings.
They Live the Longest
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.
The least common birthday is leap day, or February 29. But because the day only occurs once every four years, it's obvious it would yield the least amount of birthdays. The rarest birthday of the 365 annual calendar days is Christmas day, Dec. 25.
A study done in the U.K. showed that May is the luckiest month to be born, and October is the unluckiest. It could have something to do with that optimism, since positive attitudes have been associated with greater resilience.
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.

You know the ones I am talking about — the ones that end in a zero. The ones that make you happy when you are young, happy that you are getting older, can do more, be more. The zero birthdays as you get older that make you stop and think about your future, your life, your family, your mortality.
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.
Abstract. Month of birth influences adult life expectancy at ages 50+. Why? In two countries of the Northern Hemisphere–Austria and Denmark–people born in autumn (October–December) live longer than those born in spring (April–June).
But a statistical study of centenarians by researchers at the University of Chicago has found some other potential predictors of extreme longevity. Women and men who were the first born in large families, the study found, were two to three times more likely to make it to 100 than later-born children.
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.
Most babies (91%) in Australia are born at term (37–41 weeks).
Also meaning that December is the least common birth month, with January and February sharing a similarly low birth rate.
The Most Successful Birthdays
Out of 365 days in a year, April 30 proves to be the birthday that has produced the most winners. Among 1,000 winners or shortlisted nominees, 11 were born on this date, including Oscar-winner Cloris Leachman, one of the most celebrated actresses in history.
In concluding the study, co-author and psychologist at the University of Padova in Italy Paola Bressan noted that to the best of her knowledge, “no study has either replicated or supported” the findings from the 1995 study that stated babies resemble their fathers.
Firstborn children are taller compared to those born subsequently, and this height advantage increases sharply over the higher order of birth of siblings.
The researchers found that women who had live births had telomeres that were an average of 4.2 percent shorter than their counterparts with no children. This equates to around 11 years of accelerated cellular aging, said Anna Pollack, an epidemiologist at George Mason University and the lead researcher of the study.
Did you know? 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”.
The study found that for conceptions between January and May, gestation length declined by about a week before shooting back up to average length in June. In terms of birth weight, summer was the best time to conceive.
