Expiration Date Calculator
Calculate expiration dates for food, medicine, cosmetics and other products. Determine shelf life based on production date and product type.
Step 1: Product Information
Expiration Guidelines
Unopened products generally last longer. Once opened, exposure to air, light, and bacteria reduces shelf life. Always check manufacturer guidelines for specific products.
Step 2: Shelf Life & Storage
Storage Impact
Refrigeration extends shelf life by 2-3x for perishables. Freezing can extend it by 6-12x. Always store according to manufacturer instructions.

Expiration Calculation Formula
Expiry Date = Production Date + Shelf Life × Storage Factor
For opened products: Expiry Date = Opening Date + (Shelf Life × Opened Factor). Storage conditions significantly impact actual shelf life.
