Shelf life calculation determines the remaining time until a product expires or becomes unusable. It's calculated as the difference between the expiration date and the current date, typically measured in days.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• Expiration Date — The date when the product expires or becomes unusable
• Current Date — Today's date or the date of calculation
• Shelf Life — Remaining days until expiration (negative values indicate expired)

Explanation: The calculation provides the number of days remaining before a product reaches its expiration date.

3. Importance of Shelf Life Calculation

Details: Accurate shelf life calculation is crucial for inventory management, product quality control, consumer safety, and regulatory compliance in various industries including food, pharmaceuticals, and cosmetics.
