Terms of Service
Last updated: August 14, 2026
These Terms of Service govern your use of wondersince.com and the WonderSince lifetime comparison experience.
About WonderSince
WonderSince provides informational and entertainment-focused comparisons based on information you provide, such as your birth date.
The service is designed to help you explore historical events, lifetime statistics, planetary time, calendar curiosities and other comparisons connected to the time you have been alive.
Eligibility and use
You may use WonderSince for lawful personal purposes. By using the service, you agree not to interfere with its operation, attempt unauthorized access, misuse the website, or use it in a way that violates applicable law.
Accuracy of results
Some WonderSince results are exact calculations, while others are historical counts, derived calculations or estimates based on assumptions, averages or third-party information.
Estimated comparisons are identified where appropriate and may include explanatory assumptions or source information.
Although WonderSince aims to provide accurate and well-researched comparisons, results may contain errors, rely on incomplete information, or become outdated over time.
Informational and entertainment purpose
WonderSince is intended for general informational and entertainment purposes.
Content and results should not be treated as medical, legal, financial, scientific or other professional advice.
Third-party sources and services
Some WonderSince comparisons use information from third-party sources. WonderSince aims to identify relevant sources where appropriate, but does not control the accuracy, availability or future changes of third-party information.
WonderSince may also link to or interact with third-party services, including Facebook, X and other sharing services. Those services are governed by their own terms and policies.
Sharing WonderSince results
WonderSince may allow you to share individual comparison results through third-party platforms or device sharing features.
Shared result URLs contain the comparison and its calculated result rather than your birth date. However, some results may still indirectly reveal information about your approximate age.
You are responsible for deciding whether you are comfortable making a particular result public.

The WonderSince name, branding, visual design, original website content and software are owned by or licensed to WonderSince, except for third-party materials that remain the property of their respective owners.
You may use the website and share generated WonderSince results for personal, non-commercial purposes. You may not falsely represent WonderSince content, branding or services as your own.

WonderSince may add, modify or remove features, comparisons, datasets or other parts of the service over time.
WonderSince does not guarantee that the website or any particular feature will always be available, uninterrupted or error-free.
Disclaimer of warranties
To the extent permitted by applicable law, WonderSince is provided on an "as is" and "as available" basis without guarantees that every result, source or feature will be complete, error-free or suitable for a particular purpose.
Limitation of liability
To the extent permitted by applicable law, WonderSince is not responsible for indirect, incidental or consequential loss arising from use of the service or reliance on its content.
Nothing in these Terms excludes or limits any liability or consumer right that cannot lawfully be excluded or limited.
