Contract Renewal Notice Calculator accuracy and testing

This page documents how Calwarden builds trust for this calculator: source notes, regression-style default tests, limitations, assumptions, unit handling, rounding, and visible change history.

Formula source

  • Estimated latest notice date = renewal date minus the user-entered notice period, using calendar days or weekend-skipping business days.

Test cases

Default input regression check

Generated from the checked-in default inputs and calculate function.

Inputs

  • Renewal Date: 2026-09-23
  • Notice Period: 60 days
  • Counting Method: Calendar days

Expected outputs

  • Estimated Latest Notice Date: 2026-07-25

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

  • Renewal Date accepts calendar dates.
  • Notice Period accepts values in days.
  • Counting Method accepts one of the configured options.

Rounding rules

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