Reporting a wrong result
These are the messages we act on fastest. To let us reproduce it in one go, tell us which calculator you were on, the exact inputs you entered — including the holiday calendar and workweek selected — the date it returned, and the date you expected with the rule or statute you are counting against. A wrong result is usually either a holiday-calendar mismatch or a genuine bug in the counting, and those two details separate them immediately.
Suggesting a calculator or a holiday
Missing public holidays and regional observances are quick to add if you can point us at an authoritative source. New calculators are worth asking for too — the ones people request are generally the ones that get built, and the deadline rule you keep counting by hand is probably one other people count by hand as well.
