Terms of Use

By using DueDateCalculator.ai, you agree to these terms. Please read them — especially the part about this being an educational estimate, not medical advice.

Educational use only

DueDateCalculator.ai provides general educational information and estimated dates. It does not provide medical advice, diagnosis, or treatment, and using it does not create a doctor–patient relationship.

Estimates, not certainties

Due dates and gestational ages produced here are estimates based on standard dating methods. Actual timing varies. An early ultrasound is the most accurate way to confirm dating, and a qualified clinician sets the official due date used for your care. Always consult your clinician for decisions about your pregnancy and health.

No warranty

The site is provided “as is” without warranties of any kind, express or implied, including accuracy, fitness for a particular purpose, or availability. We work to keep the calculations correct and test them, but we do not guarantee that every result is error-free.

Limitation of liability

To the fullest extent permitted by law, DueDateCalculator.ai and its operators are not liable for any decision made, or action taken, in reliance on the information or estimates provided by this site.

Acceptable use

Please use the site for personal, lawful purposes. Do not attempt to disrupt, misuse, or reverse-engineer the service in harmful ways.

Changes

We may update these terms; continued use after an update means you accept the revised terms. Questions? Contact us.
