How does each country define the day of birth? As postnatal day 1 or 0? Or does this, for example, depend on the time of the day the child was born? In The Netherlands, day one is defined as the day of birth. Althought I have heard that this may depend on the time of the day (day 0 when born after 7 pm). So for example, if a child has a (postnatal) age 4, how old is this child? Three (i.e. approximately 72 hours) or four days (i.e. approximately 96 hours) old?
