The Jewish High Holy Days are full-day observances that require fasting and avoiding all activity except religious observances. No school. No work. No recreational activities. And it's pretty well understood that many Jews who are not particulaly observant about Sabbath-keeping are very observant when it comes to the High Holy Days.

Exactly. These days (or Christmas) are the apt comparisons to the High Holy Days. Sundays and holy days of obligation are comparable to the Sabbath, about which see above.

True. But if are on a campus in a small town where there is only one mass a day, that could prove to be a problem. I just picked Catholic as one of several. There are other religions which have all day strict observances besides the Jews who observe High Holy Days. I'm just curious about how to deal with those as well.
