All licenses issued under this title shall be valid for a period of 2 years, unless it is specifically stated in this title or by the Commissioner to be for a shorter period of time, or unless the license shall be cancelled, revoked or suspended by the Commissioner, or unless the license shall be surrendered by the licensee, or unless the license shall expire. The Commissioner shall determine the precise dates of the validity of a license issued under this title.
