1.
due date; expected date of delivery
The date on which a baby is expected to be born, as calculated by a doctor. The standard term on maternity forms and in conversation about a pregnancy.
Frequently shortened to 予定日 once the context is clear.
Common collocations
- 出産予定日が近づく: the due date approaches
- 出産予定日を過ぎる: to pass the due date
- 出産予定日より早い: earlier than the due date
Cultural note
The due date matters administratively as well as medically: Japanese maternity leave (産休) is calculated from it, normally six weeks before and eight weeks after the birth.
