🗓️ Due Date Calculator

Calculate due dates from start date and offsets for business-day or calendar-day scenarios.

This tool simply offsets the start date by the number of days you enter. It does not access pregnancy, menstrual-cycle, ultrasound, clinical, or any medical data. The common 280-day offset is just a general reference.

Results do not constitute medical advice, a diagnosis, a prenatal care plan, or any individualized pregnancy judgment. Clinical confirmation of due date and gestational age should come from a licensed physician, midwife, or prenatal care provider.

For pregnancy due date, a common offset is 280 days.

Estimate target dates by calendar days or business days. Useful for due-date planning, project scheduling, and reminders with configurable start date and day offsets. For general date estimation and educational reference only; not medical advice, a diagnosis, or an individualized basis for any pregnancy decision.
