How to report an error in a calculation or get in touch.

Reporting a wrong answer

This is the message we most want to receive. A date calculator that is quietly wrong is worse than no calculator at all, so a correction gets looked at before anything else.

The most useful report contains four things: the page address, exactly what you entered, the answer the page gave, and the answer you expected. If the disagreement is with another calculator, say which — most disagreements turn out to be a counting convention rather than a bug, and knowing which convention the other tool used usually settles it in a sentence. Either way we will say what we found.

How to get in touch

Email [email protected]. It reaches Prioton, the publisher of Datereckon, and it is the only route in — there is no form, no ticket queue and no chat widget. One person reads it; expect a reply within a few days.

Other reasons to write

  • A calculator we are missing. Especially if you can say what you were trying to work out and where you ended up looking instead.
  • A convention we have not documented. If your industry counts days in a way the methodology page does not cover, we would like to know.
  • A holiday date that looks wrong. Some of them are estimates by nature — see where our holiday dates come from — but a wrong computed date is a bug.

What not to write about

We do not accept guest posts, link exchanges, sponsored content or paid placements, and we do not add outbound links in return for anything. The answer is no; please do not follow up.

We also cannot tell you what your deadline is. See the terms of use — the arithmetic is ours, the rule that governs your deadline is not.
