Contact Us
We would love to hear from you — whether you have found a bug, want to suggest a new calculator, have a question about how one of our tools works, or need to reach us about advertising or partnerships.
The fastest way to reach us is by email:
We aim to reply to every message within 2–3 business days.
What to Include
- Bug reports: tell us which tool you were using, the dates you entered, the result you got and the result you expected, plus your device and browser.
- Feature requests: describe the calculator or option you would like to see — many of our tools started as visitor suggestions.
- Content corrections: if you spot an error in one of our blog articles, include a link to the page and the correction.
A Note on Privacy
Contacting us is entirely optional and any information you include in an email is used only to answer your message. Remember that the calculators themselves never transmit the dates you enter — everything is computed in your own browser. Read more in our Privacy Policy.
