Remaining Shelf Life
Formula:RSL = Math.ceil((expirationDate - currentDate) / (1000 * 60 * 60 * 24))
Understanding the Remaining Shelf Life Calculator
This calculator determines the remaining shelf life of a product based on the current date and the product's expiration date. It calculates the difference in days between the current date and the expiration date and rounds the number up to the nearest whole number since part of a day is considered as a full day for product expiration purposes.
The formula RSL represents the Remaining Shelf Life in days, currentDate is today's date or the date of calculation, and expirationDate is the date when the product expires. This calculator assumes a day is composed of 24 hours, an hour of 60 minutes, and a minute of 60 seconds, thereby making the calculation in milliseconds (1000 milliseconds in a second).
Data Validation
It ensures that both dates are valid and that the expiration date has not passed. It will return an error message if any date is invalid or if the product has already expired.
Practical Applications
It can be used in various industries, particularly in food and pharmaceuticals, to manage inventory and avoid selling expired products. It's also useful for consumers checking how much time they have to use a product before it expires.
