Fat Thursday is a festive day celebrated in many cultures, particularly in Poland and other parts of Europe. It occurs on the last Thursday before Ash Wednesday, marking the beginning of Lent. On this day, people indulge in rich foods, especially sweet pastries like pączki, which are filled with jam or cream. The tradition of Fat Thursday allows people to enjoy a final day of feasting before the fasting period of Lent begins. Celebrations often include gatherings with family and friends, where delicious treats are shared, and the spirit of joy and indulgence is embraced before the more solemn days ahead.
