Wisconsin’s 24-hour meeting notice rule: the 2-hour floor and the Sundays that do not count
Twenty-four hours of public notice before every meeting, a 2-hour absolute floor reserved for genuine good cause, and a counting rule that strikes Sundays and legal holidays from the clock. Here is how the rule works, where the notice has to go, and the places it catches offices off guard.
- The core rule
- Public notice of every meeting at least 24 hours before it starts (Wis. Stat. 19.84(3))
- The floor
- Shorter notice only when 24 hours is impossible or impractical for good cause, and never less than 2 hours (19.84(3))
- The counting quirk
- Sundays and legal holidays are excluded when computing the 24 hours (990.001(4)(a); DOJ OML Guide p. 19)
- Where it goes
- To the public, to news media that filed a written request, and to the official newspaper; public posting in 3 public places, or 1 public place plus the body’s website, or paid publication (19.84(1)(b))
- Per-meeting notice
- Separate notice for each meeting, reasonably proximate to the meeting date; no evergreen annual posting (19.84(4))
- Subject matter
- Time, date, place, and subject matter, including any contemplated closed session, in a form reasonably likely to apprise the public and news media (19.84(2))
The core rule: 24 hours, with a 2-hour floor
The Wisconsin Open Meetings Law states the timing rule in a single sentence. Public notice of every meeting of a governmental body “shall be given at least 24 hours prior to the commencement of such meeting unless for good cause such notice is impossible or impractical, in which case shorter notice may be given, but in no case may the notice be provided less than 2 hours in advance of the meeting” (Wis. Stat. 19.84(3)).
Read that carefully: the 2-hour floor is not an option a body picks when 24 hours is inconvenient. It is the absolute minimum for a situation where good cause makes the full notice impossible or impractical, and the DOJ’s guidance is that even then, notice should go out as soon as possible, not at hour two (Open Meetings Law Compliance Guide, March 2025, p. 18).
Good cause is undefined, so treat it as narrow
What counts as good cause? Nobody can tell you precisely, because no Wisconsin court decisions or Attorney General opinions discuss what constitutes good cause to provide less than 24-hour notice (OML Guide, March 2025, pp. 18-19). The guide fills the gap with two pieces of direction: the provision, like every provision of the Open Meetings Law, must be construed in favor of giving the public the fullest and most complete information compatible with the conduct of governmental business, and if there is any doubt whether good cause exists, the body should provide the full 24-hour notice.
The practical posture for an office: default to 24 hours every time, reserve the shortened window for the situations where the full notice genuinely cannot be given, and when you do shorten it, write down the reason at the time. If the notice is ever challenged, the record of why 24 hours was impossible or impractical is what the decision was made on, and the person defending it will be glad it exists. Notice defects are also the kind of violation that puts individual members personally on the hook; see our guide to personal fines under the Wisconsin Open Meetings Law.
The counting quirk: Sundays and holidays do not count
Here is the detail that catches offices that think of the rule as “post it the day before.” Wisconsin’s general time-computation statute provides that when a statutory period is expressed in hours, “the whole of Sunday and of any legal holiday, from midnight to midnight, shall be excluded” (Wis. Stat. 990.001(4)(a)). The 24-hour notice period is expressed in hours, so Sundays and legal holidays contribute nothing to the count.
The DOJ’s Open Meetings Law Compliance Guide applies this directly, with an example worth memorizing (March 2025, p. 19): posting notice of a Monday meeting on the preceding Sunday is inadequate, but posting that notice on the preceding Saturday would suffice, as long as the posting location is open to the public on Saturdays. Note the asymmetry: Saturdays count toward the 24 hours; Sundays and holidays do not. A body that posts Sunday afternoon for a Monday evening meeting gets credit for none of the Sunday hours; only the hours after midnight on Monday count, and they cannot reach 24. And a legal holiday falling between posting and meeting strikes another full day from the clock, so a meeting the day after a holiday generally needs its notice up before the holiday begins.
Where the notice has to go
Notice is a communication from the body’s chief presiding officer (or designee) to three audiences (Wis. Stat. 19.84(1)(b)): the public, those news media who have filed a written request for such notice, and the official newspaper designated under ch. 985, or, if none exists, a news medium likely to give notice in the area.
For the public leg, the statute gives three methods, and the body uses one of them:
- Posting the notice in at least 3 public places likely to give notice to persons affected (19.84(1)(b)1.);
- Posting in at least one public place likely to give notice to persons affected plus placing the notice electronically on the body’s Internet site (19.84(1)(b)2.); or
- Paid publication in a news medium likely to give notice to persons affected (19.84(1)(b)3.).
The second method is the modern compliance path for most offices: one physical posting plus the website replaces the errand of maintaining three physical posting locations. Two cautions ride along. The website never stands alone; it counts only paired with at least one physical public place. And the website posting satisfies the public leg only; the media-request and official-newspaper communications are separate obligations that still have to happen.
Every meeting gets its own notice
Wisconsin requires separate public notice for each meeting, given “at a time and date reasonably proximate to the time and date of the meeting” (Wis. Stat. 19.84(4)). The DOJ guide draws the practical line: a single notice listing all the meetings a body plans to hold over a given week, month, or year does not comply with the notice requirements (OML Guide, March 2025, p. 19). There is no evergreen annual posting in Wisconsin; the January notice that covers the whole year does not exist here.
This is the sharpest contrast with Wisconsin’s neighbor: Indiana lets a governing body notice its regular meetings once per year and ride that posting all year. A clerk moving between the two states, or a board member who read about the Indiana shortcut, should not import it; see our guide to the Indiana Open Door Law notice requirements for how differently that regime works.
The agenda standard: reasonably likely to apprise
Timing is only half the notice. Every public notice must set forth the time, date, place and subject matter of the meeting, “in such form as is reasonably likely to apprise members of the public and the news media thereof” (Wis. Stat. 19.84(2)). The Wisconsin Supreme Court gave that standard its teeth in State ex rel. Buswell v. Tomah Area School District, 2007 WI 71: a closed-session notice for “consideration and/or action concerning employment/negotiations with district personnel” was held vague, misleading, and legally insufficient where the school board tentatively approved a collective bargaining agreement with the teachers’ union (OML Guide, March 2025, p. 15). Sufficiency depends on the circumstances, weighing the burden of more detailed notice, the public interest in the subject, and whether the action is non-routine.
The DOJ’s rule of thumb for drafting: ask whether a person interested in a specific subject would be aware, upon reading the notice, that the subject might be discussed (p. 17). Purely generic designations such as “old business,” “new business,” or “miscellaneous business” identify no particular subjects at all and are insufficient standing alone. One mercy in the standard: sufficiency is judged on what the person posting the notice knew at the time it was posted, not on what the meeting turned out to cover. A subject that genuinely surfaced later does not retroactively poison the notice; a subject the drafter knew about and buried under a generic heading does.
The same subsection carries one more requirement that offices miss: the notice must include the subject matter “intended for consideration at any contemplated closed session” (19.84(2)). A closed session the presiding officer already contemplates at posting time belongs on the public notice, with its subject matter stated. What happens once the body actually convenes and votes to close is its own set of rules; see our guide to Wisconsin’s closed session rules.

A one-paragraph checklist
Count 24 hours backward from the meeting’s start time, then strike every Sunday and legal holiday from the count and move the posting deadline earlier to cover what you struck. Post in 3 public places, or 1 public place plus the body’s website, or by paid publication, and send the notice to every media outlet with a written request on file and to the official newspaper. Give every meeting its own notice, reasonably proximate to its date; never rely on a season or year of meetings posted at once. Name the subjects specifically enough that an interested person would know their issue might come up, including any closed session you already contemplate. And treat the 2-hour floor as what it is: a genuine-emergency provision with no case law defining it, used rarely, documented when used, and never a substitute for planning the full 24 hours.

Common questions
Do weekends count toward the 24-hour notice period in Wisconsin?
Saturdays count; Sundays and legal holidays do not. Wis. Stat. 990.001(4)(a) provides that when a statutory time period is expressed in hours, the whole of Sunday and of any legal holiday, from midnight to midnight, is excluded. The DOJ Open Meetings Law Compliance Guide (March 2025, p. 19) applies this directly: posting notice of a Monday meeting on the preceding Sunday is inadequate, but posting on the preceding Saturday would suffice, as long as the posting location is open to the public on Saturdays.
Can we post one notice covering all our meetings for the year?
No. Wis. Stat. 19.84(4) requires separate public notice for each meeting, given at a time and date reasonably proximate to the meeting. The DOJ guide (p. 19) is explicit that a single notice listing all the meetings a body plans to hold over a given week, month, or year does not comply with the notice requirements of the Open Meetings Law.
Is posting the notice on our website enough by itself?
No. Under Wis. Stat. 19.84(1)(b), a website posting counts only when paired with posting in at least one public place likely to give notice to persons affected. The alternatives are posting in at least 3 public places, or paid publication in a news medium. Whichever method is used, the notice must also go to news media that have filed a written request and to the official newspaper (or, if none exists, to a news medium likely to give notice in the area).
What counts as good cause to give less than 24 hours of notice?
Nobody knows precisely. Per the DOJ Open Meetings Law Compliance Guide (March 2025, pp. 18-19), no Wisconsin court decisions or Attorney General opinions discuss what constitutes good cause to provide less than 24-hour notice. The guide advises that if good cause exists, notice should be given as soon as possible and never less than 2 hours before the meeting, and that if there is any doubt whether good cause exists, the body should provide the full 24 hours.
How specific does the meeting notice have to be about subject matter?
Reasonably likely to apprise the public and the news media (Wis. Stat. 19.84(2)), judged case by case under State ex rel. Buswell v. Tomah Area School District, 2007 WI 71. The DOJ guide offers a rule of thumb: would a person interested in a specific subject be aware, upon reading the notice, that the subject might be discussed? Purely generic designations such as miscellaneous business identify no particular subjects at all and are insufficient. Sufficiency is judged on what the person posting the notice knew at the time of posting.
