December babies, rejoice! Research has found that people with winter birthdays tend to be less prone to irritability, while people born in the summer are more likely to experience frequent, rapid mood swings.

Feeling Moody? Blame Your Birthday

For fans of astrology, linking your mood to your birth month is nothing new. But for those of us who don't believe in horoscopes, maybe we should. There seems to be some scientific basis to the idea that your temperament is, in some small way, correlated to your birthday. In 2014, Xenia Gonda, an associate professor at Semmelweis University in Budapest, surveyed a sampling of college students to determine their temperament. "Cyclothymic temperament (characterized by rapid, frequent swings between sad and cheerful moods), is significantly higher in those born in the summer," according to a press release on the findings, while "those born in the winter were significantly less prone to irritable temperament." Gonda also found that fall babies show "a significantly lower tendency to depressive temperament" and spring and summer birthdays are significantly higher in "hyperthymic temperament - a tendency to be excessively positive."

This is not to say that if you've got a summer birthday you have carte blanche to be a jerk. And researchers still haven't figured out why these correlations exist. "We can't yet say anything about the mechanisms involved," Gonda said in the press release. "What we are now looking at is to see if there are genetic markers which are related to season of birth and mood disorder."
