Moving houses with clashing zodiac sign

I am looking to move houses between last week of February to early March. However, upon checking, the only date that doesn't have an evil direction on West (where our new house faces) clashes with my sister's zodiac sign. March 22, the next auspicious date, is already too late for us. Will it be better to choose a date with evil direction? Or can I negate the effects of the clash?
