Why a planet changes house
Your birth chart gives each planet a house by its sign. The Chalit chart draws the houses by degree instead. When the two disagree, the planet's results show in the Chalit house.
Forward
It sits past the boundary of the next house, later in the zodiac, so it is read there.
Backward
It sits before the boundary of its own house, earlier in the zodiac, so it is read in the house before.
