International Museum Day is on Tuesday, May 18, 2027, and it falls on May 18 every year. It’s a worldwide celebration of museums, from major art galleries to small-town history rooms. Many museums mark the day with special events, tours and activities.
When Is International Museum Day?
It’s on or around May 18 each year. Some museums hold events over the nearest weekend, so check your local museum’s calendar.
Who Started International Museum Day?
The International Council of Museums (ICOM) established it in 1977. ICOM is a nongovernmental organization founded in 1946 with formal ties to UNESCO.
ICOM’s stated aim for the day is “to encourage public awareness of the role of museums in the development of society.” Each year, ICOM chooses a theme tied to a challenge museums face, from sustainability to community connection. Museums around the world plan programs around it.
How big has it grown?
In 2011, nearly 30,000 museums in more than 120 countries took part, a record at the time, according to ICOM. ICOM itself links more than 30,000 museum professionals worldwide, with representatives from 137 countries and territories.
Participation ranges widely. A national museum might host late-night openings and concerts, while a village heritage room might simply open its doors for free and offer tea. Both count, and both are part of the point.
What Is the Purpose of the Day?
To highlight what museums do beyond displaying objects. They preserve history, support research, teach students and give communities a place to gather and learn.
The day also encourages people who rarely visit museums to give them a try. Small and local museums, in particular, use it to reach new visitors.
Museums depend on that support. Visitors, members, volunteers and donors all help keep collections cared for and doors open.
For families, the day is an easy entry point. Many museums plan hands-on activities, story times and trails designed for children, which can turn a first visit into a lifelong habit.

- Visit a local museum: look beyond the big names to historical societies, science centers, nature centers, historic homes and university galleries.
- Check for free entry: some museums offer free or reduced admission on the day; confirm before you go.
- Take a guided tour: docents often share stories you won’t find on the labels, and they welcome questions from curious visitors of every age.
- Explore online: many museums post digital collections, virtual tours and recorded talks.
- Bring kids: try a scavenger hunt through a gallery, or a children’s activity day.
- Volunteer or join: becoming a member or volunteer gives ongoing support.
- Share your favorite: post a photo of a favorite object and tag the museum, if photography is allowed.
