Your birth month can impact the rest of your life, and not just on your birthday.Scientists and statisticians have found that birth months affect everything from chosen career to attitude.
For instance, babies born in July are generally more optimistic through life. They’re also more likely to have vision problems.
“It seems absurd the month in which you are born can affect life chances, but how long you live, how tall you are, how well you do at school, your body mass index as an adult, your morning-versus-evening preference and how likely you are to develop a range of diseases are all correlated to some extent with the time of year in which you emerge from the womb,” Russell Foster, an Oxford University scientist, told the Telegraph.
Read ahead to find out how your birthday affects your life and to see celebrities with your birth month.
JANUARY: People born this month are statistically more likely to have Alzheimer's, Crohn's Disease and epilepsy.
Scientists have theorized this is because they're exposed to less sunlight in the womb and in the first months of their life. This could hinder development on some level and make them more susceptible to the diseases, according to the UK Office Of National Statistics.

They are also more prone the sleep disorder narcolepsy. This is because babies born this month prefer the evening hours as a result of lack of exposure to sunlight in utero and in their first months. A 9 to 5 job might not be for them.
Celebrity birthday: Ashton Kutcher
Scientists believe this is because the mothers are deprived of vitamin D, which is activated by sunlight, in the womb, hindering respiratory development. Lack of vitamin D could also hurt brain development and these children aren't as likely to do well in school. They're more likely to pursue an unconventional career, such as an artist.

Again, lack of sunlight in the womb is blamed, especially for those in Northern Hemispheres, according to George Ebers, expert of seasons at Oxford University. If the mother doesn't get enough vitamin D, many of the baby's genes aren't regulated in the womb, he said. In addition to alcoholism, they're susceptible to the highest levels of autism, depression and Seasonal Affective Disorder.

Scientists believe this has to do with sunlight exposure during pregnancy. Being deprived of sunlight during certain months interferes with different stages of development in the womb, said Russell Foster, a scientist at Oxford University. They also have consistently lower IQs for this reason, he said.

June babies finally catch a break because they receive more exposure to sunlight in utero and after birth, Ebers said. But because they weren't exposed to sunlight in the early months of development, they are more likely to suffer from vision problems, a study of 300,000 Israeli soldiers found.

They're also, like June babies, more likely to be short-sighted and need glasses because they didn't receive proper exposure to sunlight in the womb. But because they are exposed to sunlight in their first months in the summertime, they are more likely to be happy and have an optimistic outlook later, according to Foster. He calls this phenomenon 'seasonal interference.'
Celebrity birthday: J.K. Rowling
They are 30 per cent more likely than children born in September to be labelled as 'problem' students by teachers, according to the U.K. Institute for Fiscal Studies. They're at a disadvantage because they tend to be the youngest kids in the class and have trouble keeping up. Because they don't succeed in school, they're more likely to pursue a vocational career, like hairdressing.
Celebrity birthday: Barack Obama
SEPTEMBER: The highest school achievers tend to be born in September because they're the oldest in their classes.
According to the same Institute for Fiscal Studies report, they are the most likely to go to college and pursue a professional career. They're at an unfair disadvantage because they're the oldest in the class as children and master new concepts more easily.
Celebrity birthday: Charlie Sheen
They live an average of 160 days longer than those born in the spring, according to a presentation at the UK's Cheltenham Science Festival. This is because they received the optimum amount of sunlight during pregnancy and early development.
Celebrity birthday: Katy Perry
They're also known pessimists. Scientists in a 2005 Swedish study theorized this is because they're deprived of dopamine, the 'happy chemical' that's also released with exposure to sunlight, after birth. The study surveyed 30,000 people on how 'lucky' they felt, and November babies ranked the lowest.
Celebrity birthday: Ryan Gosling
This could be because they're born during peak cold and flu season, according to the American Journal of Respiratory and Critical Care Medicine. Getting a winter infection in the first four months of life could cause permanent damage, they said. And lack of sunlight in the first months makes December babies the most likely to suffer from bipolar disorder, Ebers said.
