What are the effects of rahu dasa?

The chart given by you does not show the position of earth. Earth is also a planet. Why its position is not given? The reason is that the chart is done following the most unscientific notion that the sun, moon, planets and even all the stars revolve round the earth. Therefore, all calculations including Dasha, antardasha etc. and position of stars and planets are on the basis of the discarded incorrect notion.
