Your animal does not change; what changes is the year around it. 2036 carries the number 11 (from 2 + 0 + 3 + 6), 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.
A year reading is about conditions, not Fate. The question is what 2036 makes easier and harder for the way the Horse already works.
