Shelf Life Calculator

Enter any two values among the Manufacture Date, Expiration Date, or Shelf Life (in days). The calculator will determine the missing value based on the input.

The Shelf Life Calculator is designed to compute the duration a product remains usable, its manufacture date, or its expiration date. This tool is essential for industries like food, pharmaceuticals, and manufacturing to ensure product quality and compliance. It simplifies date-based calculations and eliminates guesswork.

Formula

Shelf Life (Days): $\text{Shelf Life} = \text{Expiration Date} – \text{Manufacture Date}$
Expiration Date: $\text{Expiration Date} = \text{Manufacture Date} + \text{Shelf Life}$
Manufacture Date: $\text{Manufacture Date} = \text{Expiration Date} – \text{Shelf Life}$

Variable	Description	Unit
Manufacture Date	The date the product was produced	mm/dd/yyyy
Expiration Date	The date the product expires	mm/dd/yyyy
Shelf Life	Duration between manufacture and expiration	Days

Solved Calculations

Example 1:
Calculate Shelf Life given:

Manufacture Date: 01/01/2025
Expiration Date: 01/31/2025

Input	Value
Manufacture Date	01/01/2025
Expiration Date	01/31/2025
Shelf Life	$31 – 1 = 30 \, \tex$

Example 2:
Calculate Expiration Date given:

Manufacture Date: 01/01/2025
Shelf Life: 60 days

Input	Value
Manufacture Date	01/01/2025
Shelf Life	60 days
Expiration Date	$01/01/2025 + 60 \, \text{days}$
