No corporation shall be licensed to conduct thoroughbred horse racing with pari-mutuel wagering for more than 100 days in any calendar year. The Commission shall approve and specify the dates and hours during which the corporation may conduct such racing. Where a race program is cancelled under § 163.341 (relating to duties of stewards) before the completion of a numerical majority of the races scheduled to be raced on such program, that racing day shall not be computed as within the 100 days limitation.
