The dates of 9 - 13 December 2020 were put forward for approval to the FEI Dressage Calendar Task Force by the German FN already on 8 April 2020, but they initially were rejected, stating that the event had to be an "outdoor" competition.

The FEI Dressage Calendar Task Force has now back paddled on its recommendations and agreed that the 9 - 13 December dates and the indoor setting are good for the 2020 World Championships to go.
