Terms of Use
Last updated: July 23, 2026
By using DateSpan ("the site"), you agree to these terms. If you do not agree, please do not use the site.
Informational use only
DateSpan provides free calculators that perform calendar and date arithmetic. The results are provided for general informational purposes only. They are not professional, clinical, legal, financial, or medical advice, and they are not a substitute for the official procedures of any test manual, contract, statute, or institution. In particular, a chronological age produced here should be verified against the instructions in the relevant assessment manual before it is used to score or report a test.
No warranty
The site and its tools are provided "as is" and "as available," without warranties of any kind, whether express or implied, including but not limited to accuracy, fitness for a particular purpose, and non-infringement. While we test our calculators carefully and aim for correctness, we do not warrant that they are error-free, uninterrupted, or suitable for any specific use. You are responsible for verifying any result before relying on it.
Limitation of liability
To the fullest extent permitted by law, DateSpan and its operators will not be liable for any direct, indirect, incidental, consequential, or special damages arising from your use of, or inability to use, the site or its tools — including any decision made in reliance on a calculated result. Your sole remedy for dissatisfaction with the site is to stop using it.
Acceptable use
- Do not use the site for any unlawful purpose or in any way that could damage, disable, or impair it.
- Do not attempt to gain unauthorised access to the site, its servers, or any connected systems.
- Do not scrape, republish, or resell the site's content or code in a way that competes with or misrepresents it.
Intellectual property
The site's text, design, and original code are the property of DateSpan and are protected by applicable law. You may use the calculators for your personal or professional work and may link to any page. You may not copy substantial portions of the content for republication without permission.
Third-party links and advertising
The site displays advertising through Google AdSense and may link to third-party websites. We are not responsible for the content, products, or practices of third parties, including advertisers and linked sites. Your interactions with them are governed by their own terms and policies.

Changes
We may update these terms from time to time. Changes take effect when posted, and we will revise the "last updated" date above. Your continued use of the site after a change constitutes acceptance of the updated terms.
