By using DateCalculatorFree, you agree to the following terms. If you do not agree, please do not use this site.
DateCalculatorFree provides free, browser-based tools for calculating date differences, adding or subtracting time from a date, calculating age, counting business days, and looking up weekday information. The service is provided "as is" for informational and convenience purposes.
While we take care to implement correct calendar arithmetic, DateCalculatorFree is provided without warranties of any kind, express or implied, regarding the accuracy, reliability, or completeness of any calculation. Results should not be treated as legal, financial, medical, contractual, or professional advice. For decisions with legal or financial consequences — contract deadlines, statutory notice periods, payroll, or immigration timelines, for example — verify results independently or consult a qualified professional.
You agree not to misuse the site, including by attempting to disrupt its operation, scraping it at a rate that degrades service for others, or using it to violate any applicable law.
The design, layout, and original text of this site are owned by DateCalculatorFree and may not be reproduced without permission. The underlying date-calculation logic uses standard, publicly documented calendar arithmetic.
This site may display third-party advertisements, including through Google AdSense, to support the cost of running the service. We are not responsible for the content of third-party advertisements.
To the fullest extent permitted by law, DateCalculatorFree and its operators will not be liable for any indirect, incidental, or consequential damages arising from your use of, or inability to use, this site or reliance on any calculation it produces.
We may revise these terms from time to time. Continued use of the site after changes are posted constitutes acceptance of the revised terms.
Questions about these terms can be sent via the contact page.
