I'm not sure what you mean by TRUE and FALSE but you can most likely just test it directly:

Auto_Tog = self.AutoCheckRaw.get_active()
if AddDay_Tog:
    do so and so.

In the context of Boolean operations, and also when expressions are used by control flow statements, the following values are interpreted as false: None, numeric zero of all types, empty sequences (strings, tuples and lists), and empty mappings (dictionaries). All other values are interpreted as true.

So any reasonable values for TRUE and FALSE will work fine.
