Reporting a wrong answer
Wrong answers are the most useful thing you can send. Please include:
- The page address, or a share link from the calculator.
- The dates and number you entered.
- The holiday set (US Federal, Banks, Stock market or None) and any advanced options you changed.
- The answer DayMath gave and the answer you expected.
- If you can, where your expected answer comes from, such as a bank notice, an agency calendar or a contract.
Confirmed errors are fixed in the rules, covered by a new test, and listed in the methodology changelog.
Other questions
Suggestions for new calculators, a holiday set you need, or anything else: the same address works. DayMath cannot give legal, financial or HR advice about a specific deadline.
