Only the first two and last two days of Passover are observed as full holy days, with restrictions on work and travel. However, many extended Jewish families gather for the holiday, and consequently some Jewish students may miss other days as well, and possibly the entire week of classes. Also note that some Jewish denominations (Orthodox and Conservative) observe the full eight days, while others (Reform and Reconstructionist) observe only seven days. Consequently, some Jews will still be observing Passover dietary restrictions on the eighth day, while others will not.
