Compiling and disseminating information and data on the meetings and events organized by international organizations has been one of the UIA's core activities since 1907. This vast resource of information is published in the International Congress Calendar.
Covering meetings from 1851 to 2025, our database includes over 370,000 meetings and events, over 10,000 of which are future international meetings organized or sponsored by Intergovernmental Organizations (IGOs) and International Nongovernmental Organizations (INGOs) working worldwide. Also included are national meetings with a large international participation.
Types of Access
The Calendar is available in 4 print or PDF volumes annually, and as an online database.
