Yom HaShoah, also known as Holocaust Remembrance Day, is observed on the 27th of Nisan in the Jewish calendar, with this year's observance beginning at sunset on April 13 and ending at sunset on April 14. It is a day for Jews worldwide to reflect on the suffering of their ancestors during the Holocaust, during which approximately 11 million people were killed, including 6 million Jews. The day was officially recognized by the Israeli parliament in 1951 to honor the victims and educate future generations about the Holocaust. Customs include lighting special candles adorned with the Star of David, visiting synagogues for recitations, and sharing stories of heroism. At 10 am, sirens sound for two minutes, during which all activities pause to remember the atrocities. The observance emphasizes Jewish resilience and the importance of remembering this tragic part of history.
