Yom Hazikaron, the Israeli Memorial Day, began on Tuesday night at sundown. It begins with the sounding of the siren 8:00PM – the most noticeable feature of the day. The siren is heard throughout the country twice, during which the entire nation observes a two-minute “standstill” of all traffic and daily activities.
