Terms of Use
Last updated: 14 November 2026.
Using the site
Date Tools is free to use. By using the site, you agree to these terms. If you do not agree, please do not use the site.
What the calculators are for
The calculators provide general information only. They are not legal, financial, medical or other professional advice, and they should not be relied on for decisions where an exact date has legal or financial consequences — for example, court deadlines or contract dates. Please verify important dates from an independent source.
Accuracy
We take reasonable care to keep the calculators correct, and each tool page shows a worked example so the method can be checked. Even so, the site is provided "as is", without any warranty that the results are error-free. If you find a mistake, please report it through the Contact page.
Content
The text and code on this site are original to Date Tools. You are welcome to link to any page. Please do not copy the site's content in bulk or present it as your own work.
Availability
The site may change or become unavailable at any time, without notice. We are not liable for any loss arising from the use of, or inability to use, the site.
Changes to these terms
If these terms change, the "Last updated" date at the top of this page will change too. The current version is always the one published on this page.
