It's actually 10 months (40 weeks). I don't know where the 9 months myth came from since I also believed on it. I just learned recently with my first baby.

- TheSpiceIsLife 9y agoOnly February contains exactly four weeks (28 days), and only in non-leap years. The average month 4.345 weeks: 365 / 7 = 52.142 / 12 = 4.345 Therefore: 10 months * 4.345 = 43.45 weeks 9 months * 4.345 = 39.105 week Neither is 40 weeks. And anyway, 40 weeks is only an approximation as it is common for births to occur from 37 to 42 weeks from the first day of the woman's last menstrual period.
