Three orbits of Saturn clearly get one to old age at 88.38 years. One orbit of Uranus does, too, at 84.01. Seven of Jupiter get one to 84.02 years. One orbit of Jupiter is enough to get one through the twelve numbered grades of public school in the US. One orbit of Saturn is enough to get from birth to completing the preliminaries for careers in medicine or law. Uranus? Most people do not live long enough to survive a full orbit.

Neptune? I can't see any natural cycle that matches or approaches the time of its orbit.

Small correction to be made - One Jupiter orbit is 11.862 years, and one "Jupiter saeculum" is actually 83.034 years.
