Businesses and schools are open on Jerusalem Day, and are closed on Independence Day. Some synagogues add a special prayer on Independence Day. -- Purim is a religious occasion but is not written in the Torah itself. In Israel, there are public festivities everywhere, and schools are closed. Banks have a half-day, and businesses typically have paid leave. -- The festival of Hanukkah is a religious and festive occasion not written in the Torah itself, and is not a national holiday. Many businesses close early (around 3-4 p.m.). -- The Sabbath (every Saturday) is a day of rest on which most businesses in Israel, and banks, are closed. -- Rosh Chodesh (new month) is a Torah-occasion but not a day of rest or a holiday.

At one point during the morning service on Monday, Thursday, Saturday and holidays, the ark is opened in order to remove the Torah scroll and transport it to the table for public reading. At points during the services on some holidays, the ark is opened temporarily but the Torah is not removed. In either case, anyone in attendance at the service stands while the ark is open, as a gesture of respect toward the Torah. The prescribed prayers are sung or recited while the ark is open, then the Torah is removed if that's appropriate, then the ark is closed, and congregants return to their seats.
