Yom HaShoah

Yom Hazikaron laShoah ve-laG'vurah Hebrew: יום הזיכרון לשואה ולגבורה‎, ('Holocaust and Heroism Remembrance Day'), known in Israel and abroad as Yom HaShoah (יום השואה)  is observed as Israel's day of commemoration for the approximately six million Jews who perished in the Holocaust as a result of the actions carried out by Nazi Germany and its collaborators, and for the Jewish resistance in that period. In Israel, it is a national memorial day. 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 (falls in April or May), unless the 27th would be adjacent to Shabbat in which case the date is shifted by a day.
