Terms of Use
Last updated 30 September 2026.
About these terms
CalculationTime (calculationtime.com) is run by William Turner, Coffs Harbour, New South Wales, Australia. By using the website you agree to these terms. If you do not agree, please do not use the site.
General information, not advice
The calculators, results, articles and examples are for general information and education. They are estimates based on the inputs and assumptions shown on each page. They are not financial, investment, tax, legal, medical, engineering or other professional advice, and they do not take your personal circumstances into account.
Before making a decision that matters, such as a loan, an investment, a tax return, a building job or a health choice, check the result with a qualified professional. Health calculators are not a diagnosis and do not replace a doctor.
Accuracy
We work hard to make every calculator correct, and each one shows its formula so you can check it. Rates, laws, standards and tax rules change, and mistakes can happen, so we cannot promise that every result is complete, current or error-free. If you find an error, please tell us and we will fix it.
Liability
The website is provided free and “as is”. To the extent the law allows, we are not liable for any loss or damage arising from your use of the site or reliance on its results. Nothing in these terms excludes rights you have under the Australian Consumer Law that cannot lawfully be excluded.
Content and clock designs
The website’s text, code, graphics and calculator layouts belong to CalculationTime. The clock face designs, including the Southern Cross clock hand, are designs of Sidereal Clocks and are used with permission. You may use the calculators and print or copy results for your own personal, study or work use. Please do not copy, republish or sell the site or its designs without permission. Use of the public API and embeds is also subject to the terms on the developer pages.
Links to other sites
Source notes and references link to other websites. We are not responsible for their content, accuracy or privacy practices.
Governing law and changes
These terms are governed by the laws of New South Wales, Australia. We may update them from time to time; the date at the top shows when they last changed.
