When adjusting age for prematurity, do you round up or down to obtain gestational age in weeks? For example, if a child is born at 33 weeks, 5 days, is the child born at 33 weeks gestation or 34 weeks gestation?

The developers recommend to round the number of weeks up for 4 or more days and to round down for 3 days or less. In your example, 33 weeks, 5 days would be rounded to 34 weeks gestation. A child born at 33 weeks, 3 days would be rounded down to 33 weeks gestation.
