Non-const variables cannot be initialized at module-scope. If you don't 
need to modify the aa, declaring it immutable should allow the 
initialization to work. Otherwise, you can initialize it using a static 
module constructor.

int[string] dayNumbers;

static this()
{
    dayNumbers = ...;
}

void main() {...}
