Continuous Rotation around Y in either direction?

I’ve seen rotation questions asked occasionally over the years and this is usually the default answer:

transform.Rotate(0,6.0*rotationsPerMinute*Time.deltaTime,0);

But how would one modify this to allow continuous rotation in the opposite direction? This code rotates clockwise (if looking top-down).

transform.Rotate(0,-6.0rotationsPerMinuteTime.deltaTime,0);
