About this ranking

Some birthdays are more common than others. Births peak in late summer–early autumn (around September) and dip around year-end, Christmas, holidays like July 4 (when elective deliveries are avoided), and the leap day Feb 29. This ranking simply counts real births per date — not a made-up score or fortune.
