A "due date" is the specific date by which a task, project, or payment must be completed or submitted. It is commonly used in various contexts, such as in education for assignments, in business for invoices, and in healthcare for pregnancy. Meeting a due date is important to ensure timely completion and avoid penalties. In the context of pregnancy, a due date refers to the estimated date when a baby is expected to be born. This date is typically calculated based on the first day of the mother's last menstrual period and is usually around 40 weeks later. However, actual delivery can occur a few weeks before or after this date.
