Discrete time views values of variables as occurring at distinct, separate "points in time", or equivalently as being unchanged throughout each non-zero region of time ("time period")—that is, time is viewed as a discrete variable.Thus a non-time variable jumps from one value to another as time moves from one time period to the next. Age is commonly measured in years, which would make it a discrete variable. Think of it like this: If that number in the variable can keep counting, then its a continuous variable.
