Mourning customs are rituals and practices that people observe after the death of a loved one. These customs can vary widely across different cultures and religions, often reflecting beliefs about life, death, and the afterlife. Common practices include wearing black clothing, holding memorial services, and observing periods of silence or reflection. In many cultures, mourning customs also involve specific timeframes, such as shiva in Judaism, where family members mourn for seven days. Other traditions may include creating altars or offering food to honor the deceased. These customs help individuals and communities process grief and remember those who have passed away.
