Using public calculators
Results are informational estimates. Verify contracts, legal deadlines and official holidays independently.
Holiday data limitations
Holiday datasets show their published coverage status. Missing official holidays are not guessed; check official sources for critical deadlines.
Personal date estimates
Personal date tools are not medical advice. Do not rely on cycle estimates for contraception, and seek professional care when needed.
Accounts and saved information
Registered users are responsible for protecting their login credentials and using the service lawfully.
Email and billing
Paid checkout remains in test mode; live card payments are not offered in this release. Email reminders are optional and depend on the site owner configuring a working email service and scheduled task. Delivery is not guaranteed; do not rely on reminders as your only source for critical medical, legal or travel deadlines.
