Which Axis is north?

For simplicities sake I can see why you would use +X as north, 0.0 degrees Yaw is on the +X axis. In the real world that means East but I guess in the end it doesn’t really matter much, this question was so I could set up a compass using my characters yaw rotation, which I have already done. It’s easy for me to change the letters , I already have the range values for each direction, all they do is set a string variable to whatever letter I assign them
