duedate

DueDate is a term used to describe the date by which something is expected to be completed, delivered, or paid. It marks a deadline and is used across fields to set expectations and coordinate effort. The phrase is often written as two words, but some systems store it as a single field named dueDate.

In project management and operations, a task's due date signals when work should be finished, guiding scheduling and resource allocation. In invoicing and accounting, the due date is the payment deadline, often specified in invoices with terms such as Net 30 and may include late fees or interest. In libraries, rentals, and equipment loans, the due date indicates when the item must be returned to avoid penalties. In obstetrics, the due date (or estimated due date, EDD) refers to the expected date of delivery and is calculated from the date of the last menstrual period.

Calculation and variability: For tasks, due dates are set by project plans or calendars and can be adjusted as plans evolve; for pregnancy, the EDD is an estimate and deliveries can occur earlier or later. Some systems use business days, time zones, or working days to determine the due date.

Related terms include deadline, target date, milestone, and expiration date. The concept emphasizes accountability and scheduling, though real-world outcomes may differ from the stated due date.
