1. What is Shelf Life Calculation?

Shelf Life Calculation determines the duration between production date and expiration date of a product. It helps in quality control, inventory management, and ensuring product safety for consumption or use.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• Expiration Date — The date when the product expires or becomes unsafe
• Production Date — The date when the product was manufactured

Explanation: The calculation provides the number of days between production and expiration dates, representing the product's usable lifespan.

3. Importance of Shelf Life Calculation

Details: Accurate shelf life calculation is crucial for product quality assurance, inventory rotation (FIFO), regulatory compliance, and consumer safety across various industries including food, pharmaceuticals, and cosmetics.

4. Using the Calculator

Tips: Enter the production date and expiration date in the format YYYY-MM-DD. Ensure the expiration date is after the production date for valid results.

5. Frequently Asked Questions (FAQ)

Q1: What units does the calculator use?
A: The calculator provides results in days, which is the standard unit for shelf life measurement.

Q2: Can I calculate shelf life for multiple products?
A: This calculator calculates one product at a time. For multiple products, you would need to perform separate calculations.

Q3: What if the expiration date is before production date?
A: The calculator will return an error message as this represents an invalid scenario where a product expires before it's produced.

Q4: Does this account for leap years?
A: Yes, the date calculation automatically accounts for leap years and varying month lengths.

Q5: Can I use this for regulatory compliance?
A: While this provides accurate date calculations, always consult specific regulatory guidelines for your industry regarding shelf life documentation requirements.
