The 2021 OIDFA Congress in Tartu, Estonia has been cancelled. The anticipated dates were July 30-August 1, 2021 for the Congress, July 26-29 for workshops, and August 2-5 for tours. This follows the cancellation of the 2020 Congress in the same location. All of this due to the continuing pandemic situation.

The next Congress will be in Hamburg from August 4-6, 2023, with classes scheduled before and tours after the Congress dates.
