Are you planning on falling pregnant soon?
If you answered yes, then we have great news for you!
According to Statistics NZ, the most common birthday dates from 1980 to 2017 fall in the month of September.
To be precise, in fact, the most common birthdays fall in the 13-day period from September 22 to October 4 every year.
Which means most women get pregnant in December, around the Christmas and New Years period, more than any other time of the year.
New Zealand is not the only country where this happens. According to Stats NZ, a very similar pattern can be found in birth data from Australia, England and Wales, and the United States (which means it can't also be related to summer).
The least common day of the year to have a birthday is December 25.
