Terms of Service

1. Acceptance of Terms

Welcome to TimeDateStack (https://timedatestack.com/). By accessing, browsing, or using our calculators, date conversion tools, week number trackers, shift duration planners, and informational content, you agree to be bound by these Terms of Service ("Terms") and our Privacy Policy. If you do not agree with any part of these Terms, you must discontinue your use of our platform immediately.

2. Computational & Informational Disclaimer ("As-Is" Provision)

While TimeDateStack implements rigorous unit testing, standardized mathematical formulas (such as ISO-8601, Gregorian calendrical leap rules, Naegele's rule, and IANA timezone data), we make no warranties, representations, or guarantees of any kind, express or implied, regarding the completeness, accuracy, reliability, or fitness for a particular purpose of any computational result.

• Not Certified Payroll Software: Our payroll decimal conversions and shift calculators are estimation utilities. Employers and payroll managers must verify all timesheet summaries against official labor regulations (FLSA, state wage and hour laws) and certified accounting software (e.g., ADP, QuickBooks, Paychex).
• Not Medical Advice: Pregnancy due dates, trimester calculations, and conception estimates are approximations. They must never be used as a substitute for certified obstetric examinations, ultrasound diagnostics, or professional healthcare advice.
• Not Legal or Contractual Counsel: Business day counts, statute of limitations interval estimates, and contract performance timelines should be verified independently by licensed legal professionals.

3. Intellectual Property Rights

Unless otherwise indicated, the website design, layout, custom graphical elements, scripts, algorithms, codebases, and original written educational content on TimeDateStack are the exclusive property of TimeDateStack and are protected by applicable copyright, trademark, and intellectual property laws.

You are granted a limited, revocable, non-exclusive license to access and use TimeDateStack solely for personal, internal business, or educational evaluation. You may not republish, reproduce, duplicate, scrape, reverse-engineer, or commercially redistribute our software engines without express prior written consent.

4. Acceptable Use Policy

To the maximum extent permitted by applicable law, in no event shall TimeDateStack, its founders, engineers, contributors, or affiliates be liable for any direct, indirect, incidental, special, consequential, or punitive damages (including, but not limited to, loss of profits, business interruption, payroll calculation errors, missed contractual deadlines, or medical misjudgments) arising out of or in connection with your access to, use of, or inability to use the platform or any results generated thereby.

8. Governing Law & Severability

These Terms shall be governed by and construed in accordance with the laws of the applicable jurisdiction, without regard to its conflict of law provisions. If any provision of these Terms is deemed unlawful, void, or for any reason unenforceable, that provision shall be deemed severable and shall not affect the validity and enforceability of any remaining provisions.
