During Halloween, candy consumption reaches its peak. Every October 31, children dress up in various costumes and go door to door asking for candy, forming the tradition of "trick or treat". This custom not only allows children to enjoy a rich candy feast, but also adds a festive atmosphere to families and communities. During Halloween, businesses launch various themed candies, such as pumpkin-shaped chocolate and black candies, to attract consumers' attention and boost sales.

Christmas is also the peak season for candy consumption. Candy canes, chocolates, and various holiday-themed candies have become must-haves for family gatherings and holiday celebrations. Many families place candies under the Christmas tree as gifts, symbolizing the spirit of sharing and reunion. In addition, during Christmas, many places will hold candy-making activities, where family members participate together to enhance family ties and friendships.

Candy also plays an important role in other cultures. For example, during the Chinese New Year, candy and cakes are an integral part of the celebration. People prepare a variety of candies that symbolize sweetness and good luck and share them with friends and family to convey blessings. In Mexico's "Day of the Dead," candy skeletons and candy skulls are traditional foods for the festival, symbolizing remembrance and respect for deceased loved ones.

The role of candy is not limited to traditional festivals, and modern celebrations are increasingly incorporating candy elements. Customized candy has become a popular choice for weddings, birthday parties and corporate events, where consumers can design unique candies according to their preferences, adding to the fun of celebration.
