The annual anniversary of the death of a person is called the Yarzheit and is traditionally observed based on the Hebrew calendar. Chesed v’Emet sends a reminder in the mail a few weeks before the Yarzheit. The Yarzheit is observed by lighting a twenty-four hour candle the evening before the day of the Yarzheit. Most people recite the Kaddish and take a few moments of introspection and thought. Most congregations recite the name of the deceased whose Yarzheit is being observed during the Shabbat services closest to the date.
