In Israel they are held on a Tuesday, which is a mandatory holiday for almost everyone, and there's free public transportation anywhere if you need it in order to vote, which is cool (also, most parties would arrange for transport if you call ahead and say you need help and are planing on voting for them). If held on the weekend it would not allow Sabbath observers to vote. Not sure why Tuesday was picked specifically. Turnout is not that great in recent years though, usually around 60-70%.
