You can change a enum at runtime my altering the class at runtime before you load it. You can either compile an altered enum at runtime and load it or you can use byte code manipulation to alter it.

In short, include all the enums you need and you should never need to add to them at runtime. e.g. if there are only seven days in a weeks, include all of them at compile time.
