Bus. & Prof. Code, § 19414.5

(a) “Racing days” are days on which a licensed racing association or fair is authorized by the board to conduct horse racing.

(b) “Racing weeks” are seven consecutive days during which a licensed racing association or fair is authorized by the board to conduct horse racing for a minimum of five racing days. The board, however, upon joint petition of the association or fair and the organization representing horsemen participating in the meeting of that association or fair, may authorize the conduct of horse racing for less than five racing days. Fractional racing weeks of four days or less may be authorized by the board at the beginning and end of any horse racing meeting. Fractional weeks may also be authorized during weeks containing holidays and during periods of overlap with thoroughbred meetings and fairs if the total number of weeks authorized by the board in any calendar year for each breed does not exceed the maximum annual allocation of racing weeks provided for in Article 6 (commencing with Section 19530). If a licensed racing association holds a split meeting, each part of the split meeting shall be deemed a horse racing meeting solely for the purposes of authorizing fractional racing weeks.
