Expiration Calculator

Tool Guide

Introduction to the Online Shelf Life Calculator

The Online Shelf Life Calculator can quickly calculate whether food, medicine, cosmetics, health supplements, and other products have expired, supporting calculation of the expiration date and remaining days by three shelf-life units: day, month, and year.

After entering the production date and shelf life, the system automatically determines the "not expired / expires today / expired" status, helping you manage household daily necessities and warehouse inventory more efficiently.

It is suitable for household stockpile management, supermarket inventory counting, medicine expiration verification, and other scenarios. Note that the production date cannot be later than today.

How to Use the Shelf Life Calculator to Check Whether Food Has Expired

Step 1: Enter the production date, either by selecting it with the date picker or entering it manually.

Step 2: Enter the shelf-life duration and select the unit (day, month, year).

Step 3: Click "Start Calculation," and the system automatically generates the expiration date and status result.

Step 4: View whether it has expired and the remaining days, for subsequent use or handling decisions.
