What's the most common day of the week for babies to be born?

[ Survey Results Intro | All Charts | Take the survey ]

Right now the results for this graph are pretty flat, but the most common day for a baby to be born was Friday. I guess they want to show up in time for weekend parties. The least common day for a baby to be born was Saturday. Maybe they're afraid their first hours will be seen by too many visiting weekend relatives?
