Expiration date is the last day (in the case of American-style) or the only day (in the case of European-style) on which an option may be exercised. For stock options, this date is the Saturday immediately following the third Friday of the expiration month; brokerage firms may set an earlier deadline for notification of an option holder's intention to exercise. If Friday is a holiday, the last trading day will be the preceding Thursday.
