How this calculator works
The calculator adds or subtracts the entered notice period using the selected counting method.
Estimated Move-Out or Notice Date = start date plus or minus the entered day count, using the selected calendar-day or business-day method and optional weekend adjustment.
Inputs explained
Start date
The date the clock starts, such as notice, purchase, discovery, denial, renewal, or filing period date.
Counting rule
Use the rule from the contract, court rule, statute, plan document, agency notice, or policy.
Weekend or closure adjustment
Some rules move dates that land on weekends or closures, while others do not. Choose the rule you need verified.
Understanding your results
This is a planning estimate only. It does not decide rights, obligations, eligibility, jurisdiction, tolling, service rules, holidays, court closures, or legal compliance.
