Terms and Conditions

Last updated: 30 July 2026

1. Agreement to these terms

These Terms and Conditions govern your use of Whats My Age, available at whatsmyage.online (the "Site"). By accessing or using the Site you agree to be bound by these terms. If you do not agree with them, please stop using the Site.

These terms should be read together with the Privacy Policy and the Disclaimer, which form part of them.

2. What the Site provides

The Site provides free online calculators that perform calendar and date arithmetic, together with written material explaining the conventions behind that arithmetic.

The calculators run in your own browser. No registration, payment or account is required, and no submission of data to us is involved in using them.

The Site is provided for general information and personal use. It is not a professional service and does not create any advisory, consultative or fiduciary relationship between you and the operator.

3. No professional advice and no warranty of accuracy

The Site is provided on an "as is" and "as available" basis. To the fullest extent permitted by law, all warranties, conditions and representations, whether express or implied, statutory or otherwise, are excluded, including any implied warranties of merchantability, fitness for a particular purpose, accuracy and non-infringement.

In particular, no warranty is given that:

  • the Site will be available without interruption or error;
  • any result, figure, date or statement on the Site is accurate, complete or current;
  • the conventions used by any calculator match those required by your contract, jurisdiction, employer or institution;
  • the Site or its content is free of defects.

Nothing on the Site constitutes legal, medical, veterinary, financial, tax or other professional advice. The Disclaimer sets this out in full and you should read it before relying on any result.

4. Your responsibility for how results are used

You are solely responsible for any decision you take on the basis of information obtained from the Site, and for verifying anything that matters against an authoritative source.

Where a calculation has consequences, a legal deadline, a notice period, a medical date, an age threshold, a payment schedule, you must confirm it against the governing document, rule or professional advice before acting on it.

5. Permitted and prohibited use

You may use the Site freely for personal, educational and ordinary business purposes, including using a calculator result in your own work.

You must not:

  • use automated means to access the Site in a way that imposes an unreasonable load on it, or to scrape or copy its content at scale;
  • attempt to gain unauthorised access to the Site, its hosting infrastructure or any related system;
  • introduce malicious code, or interfere with the operation or security of the Site;
  • remove, obscure, block or interfere with advertising, notices or attribution on the Site, or frame the Site so as to do so;
  • republish substantial portions of the Site's written content as your own, or present it as your work;
  • use the Site for any unlawful purpose or in breach of any applicable law.

6. Intellectual property

Unless otherwise stated, the written content, page design, layout, graphics, code and the arrangement of the Site are owned by the operator and protected by copyright and other applicable rights.

You may quote short extracts for review, comment, teaching or news reporting, provided the extract is attributed to Whats My Age and accompanied by a link to the page it came from.

You may not reproduce, republish, translate, redistribute or create derivative works from substantial parts of the Site's written content without prior written permission.

The results a calculator produces from data you enter are yours to use however you wish. There is no claim over your figures.

Facts, dates, formulas and mathematical methods are not owned by anybody. What is protected is the specific expression on these pages.

If you believe material on this Site infringes your rights, use the Contact Us form identifying the material and the basis of your claim, and it will be reviewed promptly.

7. Advertising

The Site displays third-party advertising, which is how it is funded. Advertisements are selected and served by the advertising network, not by the operator.

The appearance of an advertisement is not an endorsement, recommendation or verification of the advertiser, its products, its services or any claim it makes. Any dealing you have with an advertiser is solely between you and them, and the operator accepts no responsibility for it.

What advertising means for cookies and data is described in the Privacy Policy.

9. Limitation of liability

To the fullest extent permitted by applicable law, the operator shall not be liable for any indirect, incidental, special, consequential, punitive or exemplary damages, or for any loss of profit, revenue, data, goodwill or opportunity, arising out of or in connection with your use of, or inability to use, the Site, whether based in contract, tort (including negligence), strict liability or otherwise, and whether or not the operator was advised of the possibility of such damage.

Without limiting the above, the operator is not liable for any loss arising from reliance on a calculation, a date, a threshold, a convention or a statement published on the Site.

Nothing in these terms excludes or limits any liability that cannot lawfully be excluded or limited, including liability for death or personal injury caused by negligence, or for fraud or fraudulent misrepresentation. Some jurisdictions do not allow certain exclusions, so parts of this section may not apply to you; the remainder continues to apply.

10. Availability and changes to the Site

The Site is offered free of charge and is provided without any guarantee of continued availability. The operator may add, change, suspend, restrict or withdraw any calculator, page or feature at any time, with or without notice, and is under no obligation to maintain any particular tool.

Content is revised from time to time as conventions, rules and sources change. Pages that are materially updated carry a revision date.

11. Changes to these terms

These terms may be updated. The current version is always the one published on this page, with the date of the last revision shown at the top. Continuing to use the Site after a change takes effect constitutes acceptance of the revised terms.

12. Severability and entire agreement

If any provision of these terms is found to be unenforceable or invalid, that provision shall be limited or removed to the minimum extent necessary, and the remaining provisions shall remain in full force and effect.

A failure to enforce any provision is not a waiver of the right to enforce it later.

These terms, together with the Privacy Policy and the Disclaimer, constitute the entire agreement between you and the operator regarding your use of the Site.

13. Governing law

These terms are governed by the laws applicable in the operator's place of residence, without regard to conflict-of-law principles. Where consumer protection law in your own country of residence grants you rights that cannot be contracted out of, those rights are unaffected by this section.
