👉 Expire dates are important in accounting and finance. They represent a specific date when an asset, such as a stock or bond, must be sold or exchanged for cash. An expiration date is also known as a maturity date. For example, if a company's stock has a 6-month expiration date, it means that the investor can sell the stock at any time up to six months from now, but cannot exchange the shares for cash until the expiration date.
