Word Choice – ‘Time-limited’ vs. ‘Time-restricted’ vs. ‘Temporary’: Understanding the Differences

In this particular case you could use dichotomy or division, since you are distinguishing between only two possibilities. (It's not actually that simple in real life, but this is English.SE not Biology.SE).

The best general antonym I can think of is (discrete) set, but you would almost never use it in the same way. You would usually use some more specific term for whatever you were talking about, which would be in turn definable as a set.

Context has a lot to do with how 'every' and 'any' will be understood, but essentially 'every' means all the instances and 'any' means one of the instances.

"I rarely have access to WiFi and don't want to use up my data so I saved your picture to my phone. I want to be able to look at it any time I look at my phone."

"You are so darn cute that I saved your picture to my phone and made it my wallpaper. I want to be able to look at it every time I look at my phone."

In the first example 'any' refers to one of many instances in which I examine my phone. In the second example 'every' refers to all of the instances in which I look at my phone. The context of both just makes the reference little more evident.
