About Global Accessibility Awareness Day
Global Accessibility Awareness Day (GAAD) is observed on the third Thursday of May to encourage people to talk, think and learn about digital access and inclusion for people with disabilities. In 2026, that date is May 21.
GAAD focuses on digital experiences such as websites, software and mobile products. The goal is awareness and better practice, not a one-day compliance certificate.
Why Global Accessibility Awareness Day matters
GAAD asks people who create, influence, fund or use technology to consider whether digital products can be used by people with different disabilities and access needs.
Accessibility work is stronger when people with disabilities are included in the process rather than treated only as subjects of testing. Personal disability information should be handled respectfully and privately.
History of Global Accessibility Awareness Day
Joe Devon wrote the blog post that inspired the idea, and Jennison Asuncion contacted him after discovering it. Official GAAD Foundation material says the two launched Global Accessibility Awareness Day in 2012.
In 2021, on GAAD’s tenth anniversary, Devon and Asuncion launched the GAAD Foundation to push digital accessibility further into technology and product-development culture.

How to Observe Global Accessibility Awareness Day
Try using a website or product with only a keyboard and note where focus, navigation or controls become difficult.
Review images, video, forms and interactive controls for meaningful text alternatives, captions, labels and clear error handling.
Include people with disabilities in accessibility research and testing with appropriate consent, compensation and privacy safeguards.
Use recognized accessibility standards and qualified evaluation methods when compliance matters; a single automated scan, checklist or GAAD activity does not by itself prove WCAG or legal compliance.
