Boy's Day (Dzień Chłopaka) is observed in Poland every September 30. This informal holiday is particularly popular among high school and university students as a way for boys to receive small gifts, such as chocolates, souvenirs, and greeting cards. The holiday likely originated to complement Women's Day on March 8, ensuring that boys also have a day to receive presents and greetings from girls. On this day, girls often take the opportunity to express their feelings towards boys they like. Special events may be organized at schools to celebrate the occasion. The popularity of Boy's Day has been increasing, aided by promotion through media and social networking sites, leading to a trend of commercialization similar to other informal holidays.
