Combine the result of the CDO operators mergetime and daymean. Here is an example: 

cdo daymean -mergetime 'file??Z' result
The assumed file names in this example are: file00Z file06Z file12Z and file18Z.
Read section "operator chaining" (https://code.zmaw.de/projects/cdo/embedded/1.6.3/cdo.html#x1-90001.2.3) for more information about wildcards in filenames.
