"Custom" refers to a traditional practice or behavior that is widely accepted within a particular group or society. These practices can include rituals, celebrations, or everyday habits that help define a community's identity. For example, the New Year's Eve celebrations in many cultures often involve unique customs, such as fireworks or special meals, that bring people together. Customs can also vary significantly from one region to another, reflecting the diverse beliefs and values of different cultures. For instance, the wedding customs in India differ greatly from those in Western countries, showcasing the rich tapestry of human traditions and the importance of cultural heritage.
