Truant’s Day is observed in Poland on March 21, marking the arrival of spring. This unofficial holiday celebrates students who enjoy truancy, allowing them to skip classes and enjoy the first warm days of the season. The tradition has become widespread, with students historically leaving notes for their teachers to inform them of their plans to celebrate the spring equinox. Nowadays, teachers often permit students to miss classes and may organize various events in honor of the day. Similar celebrations occur in the USA and Canada, where it is known as Senior Skip Day or Beach Day, although the specific dates vary by school.
