so when do we move back and forth? is it an annual thing or do we just do it all the time?

We do it all the time yearly, because the earth's orbit is elliptical, not circular. The perihelion (closest) occurs in early January and the aphelion(furthest) occurs in July.

This cycle further fluctuates because the other planets, namely Jupiter and Saturn, tug on the Earth's orbit. This cycle has many factors, but is roughly 100,000 years.
