Usually, when physical scientists use the concept of polarity, it is to describe things like electric charge (+ and -), intrinsic spin, parity (left-right), chirality, etc. However, all these do not cover entirely a complete set of directional properties and degrees of freedom. A complete set for degrees of freedom would be 8. The above polarities at the most only have 2 while chromodynamics for color charges have 3 distinct polarities say red, green and blue. Time has two polarities: past and future or two degrees of freedom but we seem restricted to only one degree of these leaving the past into the future as unidirectional linear translation. Time is really angular that is it has no motion but only orientation.
