In this paper, I have defined and explained a new simultaneity method for accelerated observers in special relativity, which I call Fontenot's simultaneity method. And I have derived an equation I call Fontenot's equation, which makes it easy to determine current age at a distance. My method focuses on determining by how much a distant person (she) ages during the transit of images (which show her age) that she transmits to an observer who sometimes accelerates. Unlike in the well-known "co-moving inertial frames" (CMIF) simultaneity method, in my simultaneity method, the accelerating traveler (he) in the twin paradox does not conclude that the home twin (she) instantaneously gets older (or younger) during the traveler's instantaneous turnaround. Instead, he concludes that, after his instantaneous turnaround, she ages faster than he does, at a linear finite rate, for a well-defined number of years, and then she ages more slowly than he does for the last portion of the return trip.
