There’s a lot of controversy over Yom haShoah as a date. One of the key issues is this: traditionally, the ways Jews mourn communal tragedies is through establishing a fast day. It’s forbidden to fast during the month of Nisan. It’s hard to pick any specific date to commemorate a tragedy as enormous as the Shoah, but one which seems appropriate to me would be 16 Marḥeshvan, the anniversary of Kristallnacht, the November Pogrom. This piyyut is a seliḥah for Kristallnacht, to be recited on 16 Marḥeshvan (or 15 Marḥeshvan on years like 5782 where the sixteenth falls on a Thursday). . . .

Pearl Benisch… remembers Passover in the Bergen-Belsen concentration camp in Germany in the spring of 1945, just days before her liberation. . . .

A Torah reading (divided into three aliyot) and a Haftarah reading to be recited for days commemorating genocides such as (but not limited to) the Holocaust. . . .

The most traumatic event in recent Jewish history is the Holocaust. At this time, the survivors of the camps are aging, and in the lifespan of people alive today it is likely that the last survivor will die. We say we must never forget what happened during the Holocaust, but if we think of it as a tragedy that happened to our ancestors we will forget. But it has been 3000 years since the Exodus from Egypt, and the Haggadah keeps its history vivid and alive. We are taught that in each and every generation we are to think of ourselves as having been slaves in Egypt. May it be that just as we never forgot the wonders of the Exodus, so too we never forget the horrors of the Holocaust, and continue to strive that such horrors may never happen again until all live in freedom and peace. . . .
