This interval between the last menstrual period to childbirth is roughly 40 weeks. Thus, the gestation period for humans in days can be calculated as 280 days. However, the actual gestation period, as compared to other mammals, is around 267 days.But then what is the average gestation period for humans? It is taken to be about 259 to 294 days.Therefore, if the birth occurs in between 259 to 294 days, it is considered to be normal, while if it takes place before 259 days, it is termed as pre-term, and if it happens after 294 days, it is called post term.ut then what is the average gestation period for humans?
