This heat chart documents the dates babies were born from 1973 to 1999, with the darker rectangles being the busiest days on the maternity ward and the lighter rectangles being the slowest days.
September 16th was most common, and surprisingly February 29th was least common.
But here's what we're wondering: how does it happen that so many birthdays fall between July, August and September? And what about the end of September, which is busy every day? Those September babies were conceived around Christmas and New Year's, which explains that busy run. And apparently people are generally having more procreative sex in the autumn and early winter, and oddly, not so much in spring, which would lead to more January babies.
So much for spring fever (which we currently have).
