About World Usability Day

World Usability Day is an international observance focused on making products, services and systems easier to access and use. It is held on the second Thursday of November.

The organization’s history places the first year in 2005. Its current site identifies Elizabeth Rosenzweig as founder and director and documents events for the 2026 edition.

Why World Usability Day matters

The day brings together user-experience, human-computer-interaction, accessibility, design, education and public-interest communities around practical usability.

It is not a certification that a particular product is accessible or usable; claims about a product or service should still be supported by appropriate testing and evidence.

History of World Usability Day

Elizabeth Rosenzweig’s account traces the idea to a 2004 conversation with Nigel Bevan while both were UPA outreach co-directors; she proposed an annual day and describes Bevan as a founding member of the first organizing committee.

World Usability Day’s archive says the observance started in November 2005. A 2010 organizer archive described it as an initiative of the Usability Professionals’ Association and identified Rosenzweig as founder and president.

The current organization says events have been held on the second Thursday in November since 2005. The date was November 12 in 2026 and is November 11 in 2027.
