Days to Expiration Calculator

Historical Background

Days to expiration calculations are widely used across various fields, including food safety, stock markets, and legal contracts. Knowing how long an item, asset, or agreement has until expiration helps ensure timely action to avoid losses, waste, or penalties.

Calculation Formula

The number of days until expiration can be calculated by subtracting the current date from the expiration date, where the formula is:

\[ \text{Days to Expiration} = \text{Expiration Date} - \text{Current Date} \]

Example Calculation

If today is September 1, 2024, and a product's expiration date is September 20, 2024, the calculation would be:

\[ \text{Days to Expiration} = \text{September 20, 2024} - \text{September 1, 2024} = 19 \text{ days} \]
