International Congress Calendar

The International Congress Calendar is a calendar of events organized by non-profit international organizations, mainly those organizations which are included in the Yearbook of International Organizations. It has been published since 1960 by the Union of International Associations (UIA) and includes over 425,000 meetings. Over 15,000 new meetings are included every year.

It is one of the most comprehensive sources of information on future international meetings organized or sponsored by international organizations. All information is provided, or confirmed, by the organizations themselves.
