Public Meeting Notice Date Calculator
Work backward from a meeting date using calendar days, business days or hours to estimate a latest notice-posting time under user-entered rules.
Estimate a public meeting notice deadline
Work backward from the meeting time using the notice period and counting method required by your rule or policy.
What the public meeting notice calculator does
The tool performs date arithmetic based entirely on the notice period and counting method you enter. It can subtract hours, calendar days, or Monday-through-Friday business days with a custom holiday list.
Why the legal rule is not hard-coded
Open-meeting and public-notice requirements vary widely by jurisdiction and meeting type. Some rules count full calendar days; others specify hours, business days, posting locations, websites or special emergency procedures.
Verify the counting convention
Whether the meeting day or posting day is included can change a legal deadline. This calculator uses a simple “work backward by the entered interval” convention and therefore should be checked against the exact wording that governs your organization.
Keep evidence of posting
Where required, retain the notice, timestamp, posting location and any publication or website record. Calculating a deadline is only one part of compliance.
Verify the legal counting convention before publishing
Public-notice laws can define “days,” “hours,” weekends, holidays, emergency meetings and posting locations differently by jurisdiction. Some rules count backward from the meeting time; others impose a minimum continuous posting period. Use the calculator only after entering the governing interval and calendar assumptions, then verify the result against the current statute, regulation, policy or counsel guidance that applies to the specific public body.
