Tomorrow may be one of the best days of the year to visit a museum, because you can get into so many museums for free.

More than 1,200 museums nationwide are participating in Smithosonian Magazine’s “Museum Day Live!” promotion on Saturday, which allows anyone to print off a special museum day ticket or display the ticket on a phone and get into a participating museum for free.

A Museum Day Live! ticket will allow one person and a guest free admission, excluding additional costs such as parking or any premium activities.

Six museums in the Bluegrass region are participating, including three local ones: Perryville Battlefield in Perryville, the McDowell House Museum in Danville and William Whitley State Historic Site in Crab Orchard.

• Perryville Battlefield State Historic Site Museum, 1825 Battlefield Road, Perryville tells the story of Kentucky’s largest and deadliest Civil War battle. Museum Day Live! Museum Day hours are 9 a.m.-5 p.m. This venue accepts Museum Day Live! tickets displayed on smartphone screens.

• McDowell House Museum, 125 S. Second St., Danville, is the house where famous physician Ephraim McDowell lived and where it is believed McDowell performed a surgery to remove a 22.5-pound abdominal tumor from a woman who previously believed she was pregnant. It was the first surgery of its type done successfully in the world. Museum Day hours are 10 a.m.-12 p.m. and 1-4 p.m. No new tours start after 3:30 p.m. Smartphone-screen tickets are accepted.
