Ohio Rev. Code Ann. § 3769.07
Except as otherwise provided in this section, no permit shall be issued under sections 3769.01 to 3769.14 of the Revised Code, authorizing the conduct of a live racing program for thoroughbred horses and quarter horses at any place, track, or enclosure except between the hours of twelve noon and seven p.m., for running horse-racing meetings, except that on special events days running horse-racing meetings may begin at nine a.m. by application to the state racing commission and except that the seven p.m. time may be extended to eight p.m. on a Sunday or holiday by application to the commission, and no permit shall be issued under those sections authorizing the conduct of a live racing program for harness horses at any place, track, or enclosure except between the hours of twelve noon and twelve midnight for light harness horse-racing meetings. The seven p.m. and eight p.m. closing times described in this section shall upon application to the commission be extended to nine p.m. for any running horse-racing meeting conducted between the fifteenth day of May and the fifteenth day of September at a track that is located more than twenty-five miles from a track located in this state where a light harness horse-racing meeting, other than a light harness horse-racing meeting at a county fair or independent fair, is being conducted and that is located less than twenty-five miles from a track located outside this state. A permit issued for horse racing at a county fair shall authorize live horse racing to begin at nine a.m. No permit shall be granted for the holding or conducting of a horse-racing meeting after the tenth day of December in any calendar year, except for racing at winterized tracks. "Winterized track" means a track with enclosed club house or grandstand, all-weather racing track, heated facilities for jockeys or drivers, backstretch facilities that are properly prepared for winter racing, and adequate snow removal equipment available. No permit shall be issued for more than an aggregate of fifty-six racing days in any one calendar year, except that an additional five days of racing may be approved by the commission upon application by a permit holder and except that an additional thirty days of racing may be granted for racing at any time after the fifteenth day of October and prior to the fifteenth day of March to a permit holder who has a winterized facility, but no more than thirty such additional days may be issued at any one track or enclosure. No more than an aggregate of fifty-six racing days shall be issued in any one calendar year for any one race track, place, or enclosure, except for the additional five days of racing for each permit holder which may be approved by the commission pursuant to this section, except as provided in sections 3769.071 and 3769.13 of the Revised Code, except for racing days granted as a result of a winterized facility, and except that the commission may issue a second permit for a maximum of fifty-six racing days for any one track, place, or enclosure, if the commission determines that the issuance of such second permit is not against the public interest. No such second permit shall be issued:
