Accuracy Disclaimer and Limitation of Liability
IMPORTANT: While we design our calculators to provide accurate results using industry-standard algorithms and rigorous testing, DateCalcPro.com makes NO WARRANTIES, EXPRESS OR IMPLIED, regarding the accuracy, reliability, completeness, or timeliness of calculation results. Our calculators are provided for general planning and informational purposes only. You should not rely solely on our calculators for critical legal, financial, medical, contractual, or other important decisions. For matters involving legal deadlines, financial calculations, compliance requirements, medical dosing, or any scenario where errors could result in significant consequences, you must verify all calculations with qualified professionals, official documentation, and authoritative sources. Different jurisdictions, organizations, and contexts may have specific calculation methods, rounding rules, or date/time conventions that our general-purpose calculators cannot account for. You assume full responsibility for verifying the accuracy and appropriateness of all calculation results for your specific use case.

Some jurisdictions do not allow the limitation or exclusion of liability for incidental or consequential damages, so the above limitations may not apply to you. In such jurisdictions, our liability shall be limited to the maximum extent permitted by law.
