Warranty Claim Deadline Calculator accuracy and testing

Formula source

• Estimated claim deadline = warranty start date plus the user-entered warranty period in months, minus the optional user-entered claim notice window.

Test cases

Known limitations

• Planning estimate/date math only; not legal advice, not an official court, agency, landlord, business, or warranty determination. Verify the lease, contract, statute, warranty terms, notices, and counsel before relying on any date or amount. Calculations run locally in your browser for privacy. The calculator does not evaluate service methods, holidays, tolling, waiver, local ordinances, lease riders, contract amendments, notice delivery proof, habitability issues, warranty exclusions, or dispute facts.

Assumptions

• All defaults are editable examples, not authoritative legal rules.
• The calculator uses the dates, periods, rates, and caps entered by the user.
• No jurisdiction-specific statute, lease rule, rent cap, deposit rule, or warranty rule is applied automatically.
• Inputs are processed locally in the browser and are not stored by Calwarden.

Unit handling

• Warranty Start Date accepts calendar dates.
• Warranty Period accepts values in months.
• Claim Notice Window accepts values in days.

Rounding rules

• Number displays use up to 2 decimal places in the calculator UI.
• Input precision follows configured step values where provided.
