Other Condition: Birth happen between 37 weeks 0 years and 38 workweek 6 years.
Full Condition: Birth come between 39 workweek 0 day and 40 week 6 day.
Tardy Condition: Birth occurring between 41 workweek 0 years and 41 weeks 6 days.
Post-term: Birth occurring at 42 hebdomad 0 days or beyond.

Why 40 Weeks is the Standard
