Your first thought is probably astrology. But astrology (how do I say this nicely?) has no scientific basis. And yet, there appears to be a more fundamental, and very earthbound, answer to this question.
According to an article in Time magazine’s daily news brief of April 17, 2017, the key may not be the month but the season of birth.
Many factors can affect development during pregnancy. Babies that do not get proper nutrition, or are even born during a famine, are at a serious disadvantage. Seasonal diseases like the flu are also a consideration. Pregnancy during the short days and long nights of wintertime can cause seasonal affective disorder (SAD) in mothers that can even carry over into the womb.
Recent research that profiled temperament in comparison with birth seasons have found some broad patterns —
Spring: March, April and May babies score high on something called the hyperthymia scale. Hyperthymia is general optimism — the ability to see every setback as opportunity for advancement. But there is a downside — spring babies are also more susceptible clinical depression. According to a study in the U.K. in 2012, people born in May are most vulnerable. November babies have the lowest depression rates.
Summer: It’s mostly positive news for June, July and August babies. There seems to be no adverse effects from SAD, at least nothing caused by the light levels after birth, though there may be some impact from mom through December, January and February. Summer babies do have some of the same hyperthymic characteristics as spring babies, but also can be influenced by cyclothymia — rapid cycling between high and low moods. Still, bipolar diagnoses are lowest among babies born in August.
Fall: People born in fall not only enjoy low levels of depression, but are less likely to develop bipolar disorder. Could it be from high nutrition availability from the fall harvest? Or perhaps because winter’s long nights and seasonal illness of winter have not yet taken hold? There is one downside — a tendency to irritability.
Winter: This is the most challenging season. Winter birth dates tend to have higher levels of schizophrenia, bipolar disorder, SAD and depression. But there are a few compensations — winter babies are less irritable than those born in fall. And there is some evidence that January and February are the best months to be born if you want to be famous; those months correlate more with creativity and imaginative problem-solving.
However, remember these results are very broad and preliminary. There is no case (yet) for trying to time a birth for a particular season. And of course, birth month is in no way a conclusive factor. Your personality is much more influenced by the multiplicity of life experiences, no matter what the season.
