Usually when Jewish people speak of something being on Jewish time, they are joking and they mean it's going to be late. There is also a Jewish time--a sense of months and even of days--that is part of Jewish religion and spirituality. Passover, like all Jewish holidays, starts and ends at sundown, and is tied to the phases of the sun and the moon. Passover always falls on the same date in the Jewish calendar. Like all Jewish holidays, Passover floats through the secular calendar. The Jewish calendar is set up to keep Jewish holidays at the same season of the year and the same phase of the moon; Passover will always begin on a full moon in the spring.
In many Reform Jewish communities, Passover is celebrated for seven days, not eight. In more traditional Jewish communities--including both Orthodox and Conservative communities--Passover is celebrated for eight days.
