Using this website
By accessing or using Universal Age Calculator, you agree to use the website in accordance with these Terms of Use. If you do not agree with these terms, you should not use the website.
The website is provided as a general-purpose online utility. No account or subscription is currently required to use the core calculator.
The information produced by this website is for general informational use and should not be treated as professional, legal, medical, financial, religious or other specialist advice.

Age calculator results
The calculator determines age by comparing the birth date you enter with the current date available to your browser. It is designed to account for ordinary differences in month lengths and leap years when presenting completed years, months and days.
Results can be affected by the accuracy of the date you enter, the date and time settings on your device, browser behaviour, and software limitations. You are responsible for checking a result before relying on it for any official or consequential purpose.
For legal eligibility, identity verification, employment, education, immigration, insurance, benefits, medical care, or other formal decisions, use the method and documentation required by the relevant authority rather than relying solely on this tool.
Hijri and calendar conversions
The site can present a Hijri birth date using calendar functionality available in the visitor's browser. Calendar conversions may differ from dates used by a particular country, community, mosque, authority, printed calendar, or observation method.
The Islamic calendar can be determined through calculated systems, local conventions, or lunar observation. For religious observance or an official date, consult the calendar or authority you normally follow.
For religious observance or official dates, use the calendar or authority you normally follow.
Western and Chinese zodiac information
Western star signs, Chinese zodiac animals, elements, and personality descriptions are included as cultural and entertainment-oriented information. Personality descriptions are general traditional associations and are not scientific assessments of an individual.
The Chinese zodiac year is determined using the browser's Chinese calendar support where available, which helps account for the fact that the Chinese zodiac year does not begin on January 1.
The optional “Are you Muslim?” setting changes presentation for a specific Chinese zodiac result. It does not change the underlying year or element calculation.
The calculator presents these results for context and entertainment, not as verified personality analysis.
Lifetime statistics and estimates
Values such as total days, hours, minutes and seconds are mathematical time calculations based on the selected date and the current time. Other features, including estimated heartbeats, breaths and sleep time, use broad assumptions for illustrative and entertainment purposes.
Those estimates are not measurements of your body, health, sleep or medical history and should not be interpreted as medical information.
Downloaded age cards and copied results
The website allows you to download an age card and copy a summary of your results. These outputs reflect the information produced by the calculator at the time they are created.
You may use your generated age card for ordinary personal and non-misleading sharing. A generated card is not an identity document, certificate, official record, proof of age, or verification issued by an authority.
You are responsible for deciding where you share downloaded or copied results. Once you share a file or text outside this website, the privacy and retention practices of the receiving service or person may apply.
Generated cards are personal summaries — not proof of age, identity documents, certificates or official records.

You must not present calculator outputs as forged official records or use the site to facilitate fraud, impersonation, or other unlawful conduct.

Availability and changes to the tool
We may update, improve, remove, replace, or temporarily suspend features as the website develops. We do not guarantee that every feature will always be available, uninterrupted, error-free, or compatible with every browser or device.
Features may also change as browser standards, calendar support, hosting infrastructure, or third-party services change.
Third-party services and external links
The live website currently relies on third-party infrastructure, including Cloudflare Pages, to deliver the service. Those providers operate under their own terms and policies.
If the website links to external resources in the future, those sites are independent from Universal Age Calculator. We are not responsible for the content, availability, security, or practices of independent third-party websites.
No warranties
The website and its results are provided on an “as is” and “as available” basis. While reasonable effort is made to build a useful and accurate calculator, no guarantee is made that every result, conversion, description, estimate, feature or piece of content will be complete, error-free, current, or suitable for a particular purpose.
You should independently verify information when accuracy is important to a decision, obligation, deadline, or official record.
This is especially important for deadlines, obligations, official records and consequential decisions.
Limitation of liability
To the extent permitted by applicable law, Universal Age Calculator and its operator will not be responsible for indirect, incidental, special, consequential, or similar losses arising from use of, inability to use, or reliance on the website or its outputs.
Nothing in these terms is intended to exclude or limit liability that cannot lawfully be excluded or limited.
Changes to these Terms of Use
These terms may be updated as the website grows, particularly if new calculators, user accounts, analytics, advertising, paid features, APIs, or other services are introduced.
When the terms are updated, the “Last updated” date at the top of this page will be revised. Your continued use of the website after an updated version becomes effective means the current terms apply to that use.
