Quick answer. Pick the state, the kind of notice and the date it was served. You'll see the earliest date the state's rule allows, the rule it comes from and the official source. For example, an Iowa landlord's month-to-month notice served Tuesday, November 10, 2026 with rent due on the 1st can name Friday, January 1, 2027 at the earliest. Confirm with the statute; local rules may add requirements.
Work out the date
Pick a state, a notice type and a date.
How the date is counted
Calendar days are counted from the day after service. "One month" is counted to the same date next month. Where the statute says the notice must name a rental date (Arizona, Iowa, Kentucky, Ohio and others) the date moves to the next rent due day; where it must end with a rental period (Florida, North Carolina, Utah, Wisconsin and others) it moves to the last day of a period. Minnesota and West Virginia count one full rental period, and Delaware counts 60 days from the first of the next month. Entry notices are counted in hours from the time the notice is given (9:00 a.m. if you leave the time blank).
Late fee limits have no date, so they're in the notice periods table with every other rule. The calculator covers state law only; 0 jurisdictions couldn't be confirmed from an official page, and the result says where to check.
Organizer information checked November 2026 against the official pages linked for each state; a few facts from vetted secondary sources, marked, not legal advice and not a legal notice form. It doesn't decide what applies to a particular lease or notice: city and county ordinances (including just-cause and rent-control rules), the lease, how the notice is served and later amendments can change the answer. Where a fact isn't confirmed from official text, the page says so and names where to check. Anything entered in the calculator stays in your browser.
Common questions
What date does the calculator give?
The earliest date the state's rule allows, counted from the day the notice was served: the earliest end of a month-to-month tenancy, the earliest date a rent increase can start, the last day of a pay-or-quit period, or the earliest entry time. Where a state requires the end date to fall on a rent day or the last day of a rental period, it moves the date forward to the next one.
Is the day the notice is served counted?
No. The count starts the day after service, which is how the Montana court instructions describe it and how most notice periods are read. A state may count differently, and mailing can add days (Kansas adds two for a mailed pay-or-quit notice; Montana's court packet says a mailed notice starts on the 3rd day). Check the statute.
What if the last day falls on a weekend or holiday?
The calculator shows the date the count reaches. Business-day rules (California, Florida, Georgia and Utah for unpaid rent) skip weekends and federal holidays; a state or court holiday in the window adds a day.
Why are there two or three dates for some states?
Some rules depend on the situation: how long the tenant has lived there (California, New York, Oregon, Vermont), the size of the rent increase (California, Maine), the tenant's age (Rhode Island), or which notice the landlord chooses (Oregon, Wisconsin). The result shows each.
Does this make my notice valid?
No. A notice usually has to follow the state's wording and service rules, and local rules can add requirements. The calculator is an organizer: confirm with the statute and your local code, and ask an attorney about a dispute.
