The Scientific and Cultural Facilities District supports cultural institutions in seven counties in Colorado, including more than 100 in Denver. The SCFD sales and tax of less than 1% helps fund free days at Denver museums and attractions. According to the SCFD annual report, the tax generated more than $47 million in revenue in 2013.

The Denver Art Museum holds free days the first Saturday of every month, while the Four Mile Historic Park holds free days the first Friday of every month. Other attractions hold free days throughout the year.  In 2015, the Denver Botanic Gardens will hold free days on Martin Luther King Jr. Day and Presidents Day, while the Denver Museum of Nature & Science will hold a free day on Earth Day.
