Food Storage Shelf-Life 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

  • Use-by date = storage date plus selected shelf-life days. Reminder date subtracts reminder lead days from use-by date.

Test cases

Default input regression check

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

Inputs

  • Storage Date: 2026-09-23
  • Food Type: Leftovers
  • Custom Shelf Life: 4 days
  • Reminder Lead Time: 1 days

Expected outputs

  • Estimated Use-By Date: 2026-09-27
  • Reminder Date: 2026-09-26
  • Shelf-Life Days Used: 4 days
  • Safety Note: When in doubt, throw it out. This reminder does not determine whether food is safe.

Known limitations

  • This page documents the checked-in calculator logic and does not certify results for every real-world edge case.
  • Use the result as a planning estimate unless the calculator page states a stricter purpose.

Assumptions

  • All prices, rates, package sizes, and recipe values are user-entered unless clearly labeled as a general planning default.
  • Calculations run locally in your browser and do not store food, nutrition, household, or budget details.
  • Use official cold-storage guidance, keep refrigerators at safe temperatures, and discard food when safety is uncertain.

Unit handling

  • Storage Date accepts calendar dates.
  • Food Type accepts one of the configured options.
  • Custom Shelf Life accepts values in days.
  • Reminder Lead Time accepts values in days.
  • Shelf-Life Days Used is displayed in days.

Rounding rules

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