The Sabbath, known to the Jewish people as Shabbat in Hebrew and Shabbos in Yiddish observe it from Friday at sunset to Saturday. Shabbat is officially over when you can see 3 stars in the sky and at that time there is a Havdalah ceremony to seperate the Sabbath from the rest of the week. A Jewish day is always sundown to sundown.
Good Friday is the day on which we remember Jesus being crucified. In the Gospels, Jesus was crucified on the day before the Sabbath (which was Saturday) to rise on the third day afterwards (on the Sunday). Therefore as Jesus was crucified on a Friday, the day on which we remember the crucifixion, is always a Friday.
Wednesday is almost always cheapest, followed by Thursday, Tuesday and Sunday. Monday, Friday and Saturday are usually the most expensive.

Jews worship the sabbath from Friday eve to Saturday eve. Christians worship the Sabbath on Sunday. I am not sure about non-Christians, or non-Jews.
