Thanks for using Timeyard, the free, privacy-first converter between the Gregorian (Miladi) and Iranian Solar Hijri (Shamsi / Jalali) calendars. We are glad to hear from you, whether you have spotted a problem, have a question, or just want to share how you use the tool.

How to reach us

The best way to get in touch is by email:

• Email or form: [OWNER: contact email or form URL]

Note for the site owner: replace the placeholder above with a real email address or contact-form link before publishing this page.

What to include in a message

A little detail helps us respond more quickly and accurately. When you write, it is useful to mention:

• What you were trying to do (for example, converting a birthday or an official document date).
• The exact dates involved, in both calendars if you have them.
• What you expected to see and what actually happened.
• Your browser and device, if you are reporting something that looks like a bug.

Reporting a wrong conversion

Accuracy matters to us. Conversion runs entirely in your browser using the proven jalaali-js arithmetic and is cross-checked against your browser's built-in Persian calendar, so results should be reliable across the supported range (Jalali years 1–1700 and Gregorian years 622–2322). If you believe a date has been converted incorrectly, please send us both the input and the result you expected, and we will investigate. If you are unsure whether the result is right, the common mistakes guide and the FAQ may help first.

Feature ideas and feedback

We keep the tool deliberately simple and focused on doing one job well. Suggestions are still welcome — if there is something that would make converting dates easier for you, let us know and we will consider it.

Privacy of your message

The converter itself collects nothing and makes no network calls when you convert a date. However, any message you send us is, by nature, shared with us through the channel above. Please avoid including sensitive personal information in your message. To learn more about how the app handles data, see our privacy policy and cookies notice.
