Most cultures adopt methods of predicting the gender of a baby before it is born. Hungarian mothers used spider webs. If the spider repaired the web after a pregnant mother stuck her finger in it, the mother was carrying a boy. Similar to the Chinese, Brazilians have a chart that uses the age of the mother and the month of conception. If the age and month are both even or odd-numbered, it is a girl. If the age is odd and the month is even, or vice versa, it’s a boy.
