It means International Day for Persons With Disabilities.
It takes place on the December 3rd every year.
The annual observance of the International Day of Disabled Persons was proclaimed in 1992 by United Nations General Assembly resolution 47/3. It aims to promote the rights and well-being of persons with disabilities in all spheres of society and development, and to increase awareness of the situation of persons with disabilities in every aspect of political, social, economic and cultural life.
We wanted to hold the Accessibility Fair on the same day as International Day for Persons With Disabilities, but it is too cold and dark by December to have an enjoyable outdoor event. We hope to have good weather for the event as there is no rain date. Please check local forecasts and dress appropriately.
