Please let Perl help you and add the following two lines to the top of your script:
use strict; use warnings;
With that, Perl will tell you that you are trying to use a variable named 2023-01-01, which isn't really allowed in your current configuration of strict.
Most likely, you wanted to print a value from %HoH:
print $HoH{"2023-01-01"}{"00:00"}; #I couldn't see the value
