A Yahrzeit candle is a special candle lit in Jewish tradition to commemorate the anniversary of a loved one's death. The candle is typically lit at sunset and burns for 24 hours, symbolizing the soul's journey and the memory of the deceased. This practice is part of the broader observance of Yahrzeit, which is the Hebrew term for the anniversary of a person's passing. Families often recite the Kaddish, a prayer for the deceased, during this time to honor their memory and reflect on their life.
