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 progress and avoid penalties. In the context of pregnancy, a due date is estimated based on the first day of the last menstrual period and typically falls around 40 weeks later. This date helps expectant parents prepare for the arrival of their baby and plan necessary arrangements, such as hospital visits and parental leave.
