Threeven

Twenty-seven is a threeven number.

Are there terms in use anywhere for numbers equal to 0 mod 3, 1 mod 3 and 2 mod 3? I need to refer to these properties and would rather use established names than invent my own. (If I do have to invent names, what do you suggest? First thing off the top of my head is "even", "surodd" and "subodd". Maybe if the use of "even" was judged confusing, "threeven" would be a cute coinage)

It just seems utterly obvious to me, along the lines of people thinking 2 is cool because it's the only "even prime" (people do this). Three is the only "threeven" prime! Five is the only "fiveven" prime! It's just a restatement of the definition.
