Your animal does not change; what changes is the year around it. 2030 carries the number 5 (from 2 + 0 + 3 + 0), which sets the tone the Horse is operating inside.
Those born in the Year of the Horse are energetic, free-spirited and sociable. This makes them reliable company, natural problem-solvers and people others instinctively trust.
The useful version of a year forecast is a list of things to watch rather than a set of predictions to wait for.
