Time is relative to the point of view of the observer. Regardless of your respective definition of a “year”, you are traveling through time in the physical universe, as measured by one or more monitoring systems devised by man to track the motion of particles through space. Here is a short list of definitions of the word “year”.

The galactic year, also known as a cosmic year, is the duration of time required for the Solar System to orbit once around the center of the Milky Way Galaxy. Estimates of the length of one orbit range from 225 to 250 million “terrestrial” years. Solar System is traveling at an average speed of 828,000 km/h (230 km/s) or 514,000 mph (143 mi/s),which is about one 1300th of the speed of light. If you could travel at that speed in a jet aircraft along the equator, you would go all the way around the world in approximately 2 minutes and 54 seconds. Even at this speed, it still takes the solar system 230 million years to orbit the center of the Milky Way Galaxy one time. Hang on and enjoy the ride!
