due date calculation

Due date calculation is the process of determining when something must be completed, delivered, or paid.

In business contexts, it typically involves adding payment terms to an invoice date: Net 30 due date calculation starts from the invoice date.

In obstetrics, due date calculation estimates when a pregnancy will reach full term, traditionally counting 40 weeks from the last menstrual period.

Software and project management tools often automate due date calculations, factoring in weekends, holidays, and business days.
