Expiration refers to the moment when something legally, contractually, or practically comes to an end. It is commonly used for time-limited rights, contracts, or products, such as visas, licenses, subscriptions, or food items. After expiration, the previous conditions, permissions, or guarantees are no longer valid or enforceable, unless they are renewed or extended. In law and business, expiration dates define the final day on which an action can be taken or a right can be exercised. In everyday use, it also indicates when a product should no longer be used, usually for safety or quality reasons.
