And don’t even start thinking about those who aren’t actively trying and the pregnancy just happens. Then they have to go back and try to figure out which day of the month it happened on? Just no.
Well and of course the concept of celebrating birthdays is far older than the understanding of conception. The whole understanding of the science of ovulation and implantation is quite new. There's a reason older texts discussed "quickening" in such detail, before modern medicine, being able to feel movement was a confirmation of pregnancy.
