Reporting a wrong result

If a calculator gives an answer you think is wrong, please send the page address and the values you entered. The easiest way is to press "Copy link" on the tool and paste that link into your email, since it holds your dates and settings. For holiday questions, tell us the country and the official source you are comparing against.

Suggesting a tool or a country

Tell us what you were trying to work out and where the existing tools fell short. Requests for public holidays in more countries or regions are especially welcome.

What to expect

We read every message and usually reply within a few working days. Corrections are tested before they go live.
