There is, however, a small minority of Jews who do not celebrate Yom Ha'atzmaut at all. Known in Israel as Charedim, or Ultra-Orthodox Jews, these Jews believe that the modern State of Israel was established prematurely without God's blessing. As a result, they refrain as much as possible from matters of the state. For everyone else in Israel, the national holiday is a welcome day off. Businesses and schools close.
Most people take a field trip or go on a picnic, while some just relax.
Religious Jews add extra prayers into the services. If 5 Iyar falls out on a Friday or Shabbat, Yom Ha'atzmaut is moved up to a Thursday, to prevent any celebrations leading to desecration of the Shabbat. But that still won't prevent you from getting head-bopped.
