Calculator assumptions matter

Each DueDate result depends on selected assumptions such as business-day versus calendar-day counting, weekend handling, holiday treatment, and whether the start or end date is included. Those assumptions are displayed to make the logic easier to review, but they may not match the rule set that governs your exact situation.

External rules may differ

Contracts, employers, agencies, courts, clients, and internal operating policies may all define deadlines differently. A date that is reasonable for planning may still need to be adjusted when a governing document or official rule uses a different method of counting days.
