If you are asking how do you get a horse to age or grow older, you simply provide adequate nutrition (food, water), shelter and veterinary care and let nature take its course.
However, I suspect what you are asking is how do you determine the age of a horse. This is generally done through examination of the teeth, particularly the cutting surface of the lower incisors. For further information about how the different shapes of the teeth indicate age, please see the related link on this question.
