From sundown on Monday, April 28 to nightfall on Tuesday, April 29, 2098. 27 Nisan 5858 · יום השואה Yom HaZikaron laShoah ve-laG'vurah (Hebrew: יום הזיכרון לשואה ולגבורה, lit. 'Holocaust and Heroism Remembrance Day'), known colloquially in Israel and abroad as Yom HaShoah (Hebrew: יום השואה, Yiddish: יום השואה) and in English as Holocaust Remembrance Day, or Holocaust Day, is Israel's day of commemoration for the approximately six million Jews murdered in the Holocaust by Nazi Germany and its allies, and for the Jewish resistance in that period. In Israel, it is a national memorial day, and several Jewish communities around the world observe it as well. The first official commemorations took place in 1951, and the observance of the day was anchored in a law passed by the Knesset in 1959. It is held on the 27th of Nisan (which falls in April or May), unless the 27th would be adjacent to the Jewish Sabbath, in which case the date is shifted by a day.
