The weekend in Israel is Friday and Saturday. On Friday everything seems to shut down around noon and they don't reopen until after sundown on Saturday. The grocery store was packed yesterday morning as everyone was getting what they needed before the weekend started. The taxis don't run unless the company is owned by Muslims. Even the city buses stop running. The parking lot to the mall is blocked off. Shabbat is truly a holy day of rest very different from how we treat Sunday in America. There used to be blue laws in America where restaurants and other businesses would be closed on Sunday but the only business I know of that is still closed on Sundays is Chick-fil-a. The only blue law still on the books I'm aware of is you can't buy alcohol on Sunday before noon.
On Shabbat some Jewish sects refrain from any work at all on Sabbath and that includes using electronics even turning on and off lights. The elevators at the hotel are set to stop on every floor on Saturday so no button pushing is required. In the rooms themselves there is a Shabbat clock that guests may use. Pressing this button will turn off all the lights in the room except for the bathroom light and desk lamp at 11pm and will turn them back on an hour before Shabbat ends. I've noticed few cars going by on the road than other days of the week. The restaurants in the hotel have restricted menus today if they are serving at all. I think the menu restrictions have something to do with Kosher food laws but I don't know much about those yet.
I will also have to get used to the idea that Sunday is going to be the new Monday for me. Once school starts I will be attending classes on Sunday's which is going to feel very strange.
