Moon - 27.3 days -
spends approx. 2.5 days in each sign

(Remember these are approximate because of the possibility of turning retrograde)

Venus - 224.5 days, spends approx. .8 months in each sign

Mars - 22 months, spends approx. 1.7 months in each sign

Jupiter - 12 years, spends approx. 1 year in each sign

Saturn - 28.9 years, spends approx. 2.5 years in each sign

Uranus - 84 years, spends approx. 7 years in each sign

Neptune 165 years, spends approx. 14 years in each sign

Pluto - 248 years, spends approx. 25 years in each sign

and then, of course, the Sun takes 365.24 days to return, spending approx. 1 month in each sign.

I'm not really sure what you are asking about doing charts 3-6 years apart, but the outer planets will be in close proximity to each other because they move the slowest.

Oh, and Chiron has an orbit of 50.7 years.
