Yom HaShoah is one of the most important events in the Hebrew calendar. Paying tribute to those who have been killed in the course of Holocaust, lots of memorial events take place all over the country. However, the highlight moment occurs at 10 AM on the day of Yom HaShoah. Dozens of air-raid sirens sound to divert everybody from the routine and pray for the victims of Nazi regime. The event ranks amongst the most important ones of the country and having heard the siren everyone stops and stands still no matter what s/he was doing before. The remembrance day is a truly impressive event, as there are no indifferent to the memory of fallen ones. It's definitely not the best time to have fun in Israel, as all places of public entertainment are closed and all the nation mourns for the victims of the Holocaust. So, please, be respectful and spend the day as the locals do.
