meaning - Is this mathematical explanation of "except" and "other than" right?



This question is derived from this one.


Assume "not including" and "including" have two mutually exclusive meanings. It is impossible "not including" and "including" at the same time.


The Oxford dict gives this example of except.



They work every day except Sunday



In the form of set (math), we have 2 sets in there



  • on set_1 = {Monday, Tuesday, Wednesday, Thursday, Friday, Saturday} they work

  • on set_2 = {Sunday} they don't work



set_1 is not including Sunday, this is what "except" does mean, "other than" has the same meaning. Is my understanding right?
