Terms of Use شرایط استفاده

These terms apply to your use of Timeyard, a free online tool for converting dates between the Gregorian calendar and the Iranian Solar Hijri (Shamsi or Jalali) calendar. By using the site, you agree to the terms below. If you do not agree with them, please do not use the tool.

Owner and legal review: this page is written in plain English to describe how the tool actually works. It is general information, not legal advice, and it requires review by the site owner and a qualified lawyer before it is relied upon. A few details below use sensible defaults (the operating name and the governing jurisdiction) that the site owner should confirm before publication.

What the tool is

Timeyard is an informational date converter. It runs entirely in your browser, performs its conversions locally with no server and no network call for the conversion itself, and can work offline after your first visit. There is no account, no sign-in, and nothing to buy. It is provided free of charge for personal and everyday reference use.

Acceptable use

You may use the converter for any lawful purpose, including converting birthdays, document dates, and historical dates. In return, you agree not to:

• use the tool for any unlawful purpose or in breach of any applicable law or regulation;
• attempt to disrupt, overload, or interfere with the site, its hosting, or its availability to others;
• attempt to gain unauthorised access to any part of the site or its underlying systems;
• misrepresent the tool as your own product, or imply that the maintainer endorses your use of it; or
• remove, obscure, or alter any notices on the site.

You are responsible for the dates you enter and for how you use the results.

Accuracy and disclaimer

We take accuracy seriously. Conversions are computed with a well-established calendar method and are cross-checked against your browser's built-in Persian calendar, and the tool covers Jalali years 1 to 1700 and Gregorian years 622 to 2322. You can read more about the method and its limits in our guides on leap years, the Persian months, and common conversion mistakes.

Even so, the tool is provided "as is" and results are offered for general information only. For any critical or official purpose (legal documents, immigration or visa paperwork, contracts, medical records, or anything where a wrong date has consequences) you should verify the converted date independently against an authoritative source. We do not guarantee that every result is correct for your particular use, and you should not treat the output as an official or certified conversion.

No warranty

To the fullest extent permitted by law, the site and its content are provided without warranties of any kind, whether express or implied. We do not warrant that the tool will be uninterrupted, error-free, available at all times, free of harmful components, or fit for any particular purpose. Your use of the tool is at your own risk.

Limitation of liability

To the fullest extent permitted by law, the maintainer of this site will not be liable for any loss or damage arising from your use of, or inability to use, the tool or from reliance on any result it produces, including any indirect, incidental, or consequential loss. This does not limit any liability that cannot be excluded under applicable law. (Site owner: confirm the wording of this clause with a lawyer for your jurisdiction.)

Intellectual property

The design, text, and code of this site belong to the site owner unless stated otherwise, and third-party open-source components remain the property of their respective authors under their own licences. You may use the converter and read these pages for your own reference, but you may not copy substantial parts of the site's content or code, or reproduce or republish them, without permission, except as the relevant open-source licences allow. The project is published as Timeyard, with its open-source components remaining under their respective licences. (Site owner: confirm the copyright holder and any licence under which the code is released.)

Advertising and analytics

To support the free tool, the site may show advertising and use privacy-respecting analytics, which load third-party scripts and may set cookies, and only where you have given any required consent. These are separate from the date conversion, which always runs locally in your browser and is never sent to a third party. How that works, and your choices, are described in our Privacy Policy and Cookie Policy.

Links to other sites

This site may link to external pages we do not control. We are not responsible for the content, accuracy, or practices of any third-party site, and a link does not imply our endorsement of it.

Changes to these terms

We may update these terms from time to time, for example to reflect changes to the tool or to the law. The current version always applies and is the one published on this page. Please check back occasionally; continued use of the site after a change means you accept the updated terms.

Governing law

These terms, and any dispute arising from them or from your use of the site, are governed by the laws of England & Wales, and the courts of England & Wales will have responsibility for any such dispute, except where applicable law gives you rights to bring proceedings elsewhere. (Site owner: confirm the governing jurisdiction for your situation.) Nothing in these terms affects your statutory rights as a consumer.

Contact

If you have a question about these terms, please use the details on our Contact page. You can also learn more about the project or return to the date converter.

This page is a plain-English template describing the tool honestly. It is not a guarantee of compliance with any specific law and must be reviewed by the site owner and a qualified legal adviser before it is relied upon.
