In a new study, scientists created a heatmap that shows most people on Earth were born at the same time.
If you’ve ever wondered how many other people on the planet celebrate your birthday on the same day – rejoice, researchers have answered that question. The Daily Mail writes that researchers have created a heatmap that plots the most common and least common dates for the births of people on Earth.
Statistics show that most people in the world are born in September and July, while the rarest birthdays are in November, December and January. Curiously, some of the most common birthdays are September 12, 18, 25, and 26, which are about 9 months after the New Year holidays.

At the same time, Christmas and New Year’s were among the days with the lowest probability of birth, but this is not surprising. But scientists have also noticed that other public holidays also become the days when births are least common.
Scientists believe this is due to the fact that most hospitals do not schedule caesarean sections and other operations on public holidays, in most cases only emergency surgical interventions are performed.
The popularity of birthdays in September is linked to cold winter weather, which encourages people to stay home more often, researchers say. In the entire dataset, September 9 is the most common birthday, while September 19 is the second most common.
In addition, scientists have determined the best time and months to have sex in order to have children. The results of the study show that it is better for couples to focus on having sex before 7:30 a.m. on a spring morning. Researchers at the University Hospital Zurich believe that sperm cells have their own 24-hour internal clock, which is most active in the early morning.
Swiss researchers also found that sperm have the healthiest size and shape to fertilize an egg in March, April and May. Next, the study analyzed semen samples from more than 7,000 men aged 25 to 40 who were being treated for infertility. Samples were cross-checked for sperm concentration, total sperm count, progressive motility and normal morphology.
