World Usability Day is celebrated every year on the second Thursday of November. The initiative to implement the holiday belongs to the Association of Usability Professionals (UPA), and the celebration of the holiday began in 2005.

The word Usability in translation means ease of use. For any project, ease of use, practicality and convenience are important, which is why usability specialists try to take into account all factors when creating a product for widespread mass use.

The essence of the World Usability Day is to draw public attention to the need to increase the ease of use of services and products that are necessary and important for society.
