Corrections are the most useful thing you can send. If a rule here does not match the text of the rule as your court applies it, we want to know.

Report an incorrect rule
Email contact@courtdaycalculator.com with the rule page URL, the citation, and what the correct period should be. A pinpoint citation to the governing text lets a correction go out much faster.
Every rule page states whether its encoding has been checked against the official text. Where it has not, treat the numbers as a starting point and confirm them yourself.
Request a jurisdiction
The calculator currently covers 58 federal and California deadline periods. If you would use a different state or a specific local rule set, say which court and which deadlines matter most in your practice — that is what drives what gets added next.
Questions about the methodology
How the counting sequence works, what is modeled, and what is deliberately not modeled are all set out on the methodology page. If something there is unclear or looks wrong, that is also worth an email.
What we cannot help with
We cannot give legal advice, tell you whether a particular deadline applies to your case, or review your calculations for a live matter. Those questions belong with a licensed attorney in your jurisdiction.
