About Expiry Date Calculator

The Expiry Date Calculator helps you determine when a product will expire based on its manufacturing or purchase date and shelf life duration. Whether you are tracking food freshness, medication validity, or any perishable item, this tool gives you the exact expiry date along with a real-time freshness status.

Choose from common product presets like milk, bread, or canned food for quick calculations, or enter a custom shelf life in days, weeks, months, years, or hours.

Frequently Asked Questions

What is an Expiry Date Calculator? expand_more
An Expiry Date Calculator computes the exact date when a product will expire by adding a shelf life duration to a start date. It shows the freshness status (Fresh, Warning, or Expired) and calculates remaining time in multiple units.
How does the warning period work? expand_more
When you enable the Set Warning Period option, you can specify a number of days before expiry to trigger a warning. If the current date falls within that warning window, the status changes from Fresh to Warning, alerting you to use the product soon.
What do the product presets do? expand_more
Product presets are quick-fill buttons for common items like Milk (7 days), Bread (5 days), Fresh Meat (3 days), and others. Clicking a preset automatically fills in the shelf life duration and unit so you only need to set the start date.
Can I calculate expiry for items measured in months or years? expand_more
Yes. The tool supports five duration units: Days, Weeks, Months, Years, and Hours. For medications or canned goods with long shelf lives, simply select Months or Years from the dropdown.
Is my data private? expand_more
Yes. All calculations happen locally in your browser using JavaScript. No product data or dates are transmitted to any server. The tool works fully offline once loaded.
