This was the first German Chmps since the war. It would take German tennis years to recover, as many countries banned Germans from entering their tournaments until later in the decade. It is also likely that few non-Germans entered the 1920 championships.
The German Chmps was played around the middle of August and in Hamburg in the 1920s (just as before WWI). I would put it to the week finishing at Aug 15.
There were smaller events in Berlin in the spring, around Eastern (just as before WWI).
The German tournaments continued to be played in around the same time-slot as before WWI.
